Hardware Context Protocol (hc.v0) --------------------------------- Splits device integration along what can be known. HardwareContext describes what an agent must know to command a device safely -- quantities, units, operating envelopes, interlocks, settling time, reversibility -- and is fixed by physics rather than by any wire protocol. HardwareTransport is a six-method contract for how a command reaches the device, and can be swapped freely. Two kind->factory seams (providers/, transports/) make supporting another southbound standard a module plus a table row; an architecture contract test keeps upstream standard concepts out of the domain model so that stays true. - Eight generic tools, count independent of device count (progressive disclosure). Writes split by effect class so each reaches its own ActionKind instead of a generic fallback. - Envelope-derived hardline denials: out of range, unsatisfied or unevaluable interlock, undeclared envelope, unverified context, effect-class mismatch. Rate limiting is a retryable refusal, not a hardline: the same command becomes valid after waiting. - Physical writes declare effect_scope=external, so a failed command is not replayed and its side-effect verdict reaches the next turn. Re-running an aspirate dispenses twice; an error is not proof that nothing happened. - Grant identity is device:channel@envelope-band. One consent covers the band, and widening the declared envelope invalidates the narrower grant it was given under. - Sampling keeps raw readings out of SignalBuffer (capacity 50); only envelope-derived events cross into the interaction signal pipeline. - Raw samples persist as session-scoped, sensitive, non-syncable, TTL-bounded cache artifacts; downsampled windows go to instrument.duckdb. - Physical outcomes compute a numeric, envelope-normalised delta with no model call and land in ExperienceStore, so an optimisation performed once becomes a starting point rather than an experiment to repeat. Off by default. With hardware disabled the plugin exposes no tools and the risk classifier is the unmodified default, leaving the tool index byte-identical. MCP approval bypass (security) ------------------------------ MCP tool schemas carried no x_leapflow metadata and the handler was a bare passthrough, so third-party server code ran with this agent's privileges with no risk classification, no consent, and no audit record -- the only sensitive capability in the process reachable without the orchestrator. - ActionKind.MCP_TOOL, assessed on provenance rather than on the description the server wrote about itself. - The handler routes through ApprovalOrchestrator, resolved per call so the daemon-side gate applies. Fails closed on absence and on exception. - readOnlyHint is honoured where present; its absence is not a safety claim, so unannotated servers stay gated. - Descriptions matching prompt-injection patterns are refused registration rather than logged, because they are injected verbatim into the tool index. - mcp.approval_mode: mutating_only (default) | always | off. Reviewer note: security/actions.py, security/risk.py, cli/context.py and the two config modules carry hunks from both concerns, so splitting at hunk granularity risked a non-building intermediate commit. The security-module surface worth reviewing on its own is the six new ActionKind values, ActionDescriptor.device() and .mcp_tool(), and the two _normalize_detail branches -- together they define the grant contract for both domains. Config: mcp.approval_mode plus 11 hardware.* keys, all discoverable through leap config and all restart-required. Tests: 2708 passed, 2 skipped, 1 xfailed (+142); journeys 7 passed with cassette fingerprints unchanged; ruff clean on new and modified files. --- src/leapflow/cli/context.py | 248 ++- src/leapflow/config.py | 87 ++ src/leapflow/config_service.py | 60 +- src/leapflow/daemon/approval_coordinator.py | 7 + src/leapflow/hardware/__init__.py | 86 ++ src/leapflow/hardware/context.py | 586 ++++++++ src/leapflow/hardware/outcome.py | 385 +++++ src/leapflow/hardware/plugin.py | 116 ++ src/leapflow/hardware/providers/__init__.py | 113 ++ .../hardware/providers/yaml_provider.py | 128 ++ src/leapflow/hardware/reading_store.py | 406 +++++ src/leapflow/hardware/reference.py | 224 +++ src/leapflow/hardware/registry.py | 789 ++++++++++ src/leapflow/hardware/risk.py | 276 ++++ src/leapflow/hardware/stream.py | 501 +++++++ src/leapflow/hardware/tools.py | 824 ++++++++++ src/leapflow/hardware/transport.py | 203 +++ src/leapflow/hardware/transports/__init__.py | 93 ++ src/leapflow/hardware/transports/mock.py | 225 +++ .../hardware/transports/python_callable.py | 77 + src/leapflow/layout.py | 39 + src/leapflow/platform/mcp_manager.py | 62 +- src/leapflow/plugins/tool_plugins/__init__.py | 5 + src/leapflow/security/__init__.py | 10 +- src/leapflow/security/actions.py | 166 ++ src/leapflow/security/risk.py | 81 +- tests/test_architecture_contracts.py | 86 ++ tests/test_hardware_context.py | 686 +++++++++ tests/test_hardware_governance.py | 1336 +++++++++++++++++ tests/test_hardware_outcome.py | 673 +++++++++ tests/test_hardware_reading_store.py | 513 +++++++ tests/test_hardware_stream.py | 509 +++++++ tests/test_hardware_transport_contract.py | 240 +++ tests/test_mcp_governance.py | 430 ++++++ 34 files changed, 10263 insertions(+), 7 deletions(-) create mode 100644 src/leapflow/hardware/__init__.py create mode 100644 src/leapflow/hardware/context.py create mode 100644 src/leapflow/hardware/outcome.py create mode 100644 src/leapflow/hardware/plugin.py create mode 100644 src/leapflow/hardware/providers/__init__.py create mode 100644 src/leapflow/hardware/providers/yaml_provider.py create mode 100644 src/leapflow/hardware/reading_store.py create mode 100644 src/leapflow/hardware/reference.py create mode 100644 src/leapflow/hardware/registry.py create mode 100644 src/leapflow/hardware/risk.py create mode 100644 src/leapflow/hardware/stream.py create mode 100644 src/leapflow/hardware/tools.py create mode 100644 src/leapflow/hardware/transport.py create mode 100644 src/leapflow/hardware/transports/__init__.py create mode 100644 src/leapflow/hardware/transports/mock.py create mode 100644 src/leapflow/hardware/transports/python_callable.py create mode 100644 tests/test_hardware_context.py create mode 100644 tests/test_hardware_governance.py create mode 100644 tests/test_hardware_outcome.py create mode 100644 tests/test_hardware_reading_store.py create mode 100644 tests/test_hardware_stream.py create mode 100644 tests/test_hardware_transport_contract.py create mode 100644 tests/test_mcp_governance.py diff --git a/src/leapflow/cli/context.py b/src/leapflow/cli/context.py index b33ce39..1df692d 100644 --- a/src/leapflow/cli/context.py +++ b/src/leapflow/cli/context.py @@ -68,6 +68,16 @@ logger = logging.getLogger(__name__) +_MCP_THREAT_BLOCK_SEVERITY = 0.8 +"""Severity at or above which an MCP tool description is refused registration. + +Set where the classic injection patterns sit ("ignore all previous instructions", "your +new instructions are") rather than lower, because a tool description is *supposed* to +contain imperative language about what the tool does.

Clock domains and sampling -------------------------- Reading carried one timestamp taken from time.monotonic() and persisted it as a wall-clock instant, so stored history was unreadable across restarts and could not be compared with any other subsystem. Split into observed_at (wall) and monotonic_at (per-boot), mirroring the convention SystemEvent already declared. - Sampling schedules against a deadline instead of sleeping a fixed interval, so a slow read no longer accumulates drift; missed slots are counted, not hidden. - Persistence moved off the sampling path via asyncio.to_thread. - Per-kind event pacing, so a paced rate_exceeded cannot hide a first-time threshold_exceeded behind it. - Threshold hysteresis derived from the declared envelope quantization rather than a new knob: a value hovering on a bound no longer emits a breach per sample. Breach uses the human's limit exactly; recovery uses the margin. - Per-device I/O mutex. An interleaved read and write on one bus lands a command on the wrong channel, and that outcome is indistinguishable from success. Reachability precedes consent ----------------------------- registry.transport() ran after approval, so commanding a device that was never reachable produced a prompt, a consent, and only then the failure. Asking somebody to authorise an undeliverable command is how people learn to click through prompts -- and the prompt they learn to dismiss guards the commands that can be delivered. The check probes rather than only opens, because transport() caches: a session that died is handed back without open() running again, which is the common failure for a server-backed device. A dead transport is dropped so the refusal cannot outlive the outage. hw_estop is deliberately exempt: refusing to attempt a stop is worse than attempting one that fails. MCP transport ------------- transports/mcp.py is the second southbound implementation and therefore the first real test of the seam's claim. Measured: one new module, one lookup row, and sixteen lines in cli/context.py to install the client resolver -- with zero lines changed in the domain model. The third file is specific to MCP being already present in the process as a control plane; a self-contained standard would not need it. Everything device-specific is declared: tool names, argument names, the response key holding the value. No name matching and no fallback chain, because a guess that lands on the wrong tool is a physical action nobody authorised and nothing downstream can detect it. A failed write reports UNKNOWN unless the server says otherwise -- the MCP client turns a timeout into an ordinary error reply, so a failure genuinely cannot distinguish "never sent" from "sent, no answer". The conformance suite hardcoded _TRANSPORT_CASES[0] for its two most consequential cases -- an error is not proof that nothing happened, and "cannot stop" must be declared -- so every transport after the first was covered by fourteen cases and silently exempt from those two. Now parameterised per case. Storage governance ------------------ reading_windows had no retention, no index, and no way to remove the rows whose timebase was unusable. Retention runs on the write path, so the only process that grows the table is the one that trims it. Raw files roll at a byte cap and are re-indexed per append: CacheManager records the size it finds at registration, so a file indexed once and appended to for hours was accounted at its first few kilobytes with a TTL counting down from the first sample. LeapBoard --------- New hardware lens: device inventory, channel traces, envelope conformance, sampling health, learned command outcomes, storage state. Two panels deliberately expose problems rather than hiding them -- observed-versus-declared rate makes sampling drift visible, and unpersisted-window count makes a locked database visible, since a database that cannot be opened otherwise looks exactly like an idle bench. - capability lens rendered nothing: its producer set only evidence, never payload, which is what the template binds to. Four tables also used a mapping repeat and a node-level bind, both of which render_node ignores. Correct headings over zero rows, with nothing reporting a fault. - Board i18n covered only the two original lenses. Five of seven shipped English in every language -- capability 0 of 31 strings, hardware 14 of 44 -- while the i18n test checked signal keys and stayed green. 100 strings x 5 locales added, with coverage now asserted per template and per locale. - /board gained completion for its second token. It accepts a reserved verb or a lens name in the same position and offered neither, so both were reachable only by reading the source. Physical learning ----------------- predicted_effect was always "reach ", so the residual measured the device and could never improve: a valve that always ran eight percent low reported the same error on its thousandth command as its first. Outcomes now carry a second residual measured against a prediction derived from prior observations, which is the only one a learning loop can drive down. No LLM call -- the physical predictor is the command plus a learned bias, clamped to a quarter of the declared span. The calibration is per session and says so. Concurrency ----------- Seven stores captured holder.connection in __init__, permanently binding the root connection and defeating the per-thread cursor mechanism entirely. Two threads then reached DuckDB concurrently and the daemon hung before answering its first status call -- 37% of runs, reproduced against HEAD. Now resolved per call. daemon.status also read the watch store inline on the event loop; that read is now serialized off-loop. Execution policy ---------------- x_leapflow.risk_level carries seven values (a disclosure grading) while ToolSpec.RiskLevel has three (a side-effect classification). plugin_generate declared medium and was parsed as read_only, so the ledger deduplicated it, it ran freely in parallel, and no side-effect gate applied. An explicit no-effect claim now outranks a substring guess about the name; exactly one built-in tool changes behaviour. Also: PluginHealthProducer registered (its docstring claimed it already was), interval watch dedup keys fixed, sync_fixtures --check no longer fails on corpus growth, AGENTS.md gains the plugin and extension rules. Verified: 2799 passed, 55 regression, 7 journeys, i18n coverage complete at 7 templates x 5 locales. Static analysis unchanged from baseline. --- AGENTS.md | 41 +- src/leapflow/cli/commands/interactive.py | 18 + src/leapflow/cli/context.py | 59 +- src/leapflow/cli/tui_app/app.py | 12 +- src/leapflow/cli/tui_app/input.py | 59 +- src/leapflow/config.py | 14 + src/leapflow/config_service.py | 12 + src/leapflow/daemon/monitor_coordinator.py | 109 +++- src/leapflow/daemon/service.py | 6 +- src/leapflow/dashboard/service.py | 81 ++- src/leapflow/dashboard/static/app.js | 85 ++- .../dashboard/templates/capability.yaml | 84 ++- .../dashboard/templates/hardware.yaml | 183 ++++++ src/leapflow/domain/events.py | 10 + src/leapflow/hardware/context.py | 57 +- .../hardware/observability/__init__.py | 36 ++ src/leapflow/hardware/observability/digest.py | 383 +++++++++++ .../hardware/observability/producer.py | 165 +++++ src/leapflow/hardware/observability/series.py | 287 +++++++++ src/leapflow/hardware/outcome.py | 156 ++++- src/leapflow/hardware/reading_store.py | 305 ++++++++- src/leapflow/hardware/registry.py | 107 +++- src/leapflow/hardware/stream.py | 274 ++++++-- src/leapflow/hardware/tools.py | 132 +++- src/leapflow/hardware/transport.py | 28 +- src/leapflow/hardware/transports/__init__.py | 1 + src/leapflow/hardware/transports/mcp.py | 373 +++++++++++ src/leapflow/hardware/transports/mock.py | 2 - src/leapflow/monitor/__init__.py | 2 + .../monitor/capability_adaptation_producer.py | 9 + src/leapflow/monitor/finding_store.py | 14 +- .../monitor/plugin_health_producer.py | 7 +- src/leapflow/platform/event_bus.py | 6 +- src/leapflow/platform/normalizer.py | 9 +- src/leapflow/scheduler/store.py | 14 +- src/leapflow/storage/connection.py | 16 + src/leapflow/storage/conversation_store.py | 12 +- src/leapflow/storage/evolution_store.py | 12 +- src/leapflow/storage/session_store.py | 12 +- src/leapflow/storage/skill_library.py | 12 +- src/leapflow/storage/trajectory_store.py | 16 +- src/leapflow/storage/write_buffer.py | 19 +- src/leapflow/tools/name_resolver.py | 73 ++- ...sette-model-99a5ae1bc0719c4d.cassette.json | 75 +++ ...sette-model-fffcdbe5759f5a6b.cassette.json | 71 +++ .../llm_responses/response_shapes.json | 3 +- tests/regression/test_provider_shape_drift.py | 29 +- tests/test_architecture_contracts.py | 86 ++- tests/test_daemon_event_loop_blocking.py | 82 +++ tests/test_dashboard_domains.py | 99 ++- tests/test_dashboard_i18n_static.py | 100 +++ tests/test_dashboard_sdui.py | 70 +++ tests/test_dashboard_watch_rpc.py | 2 +- tests/test_hardware_context.py | 68 ++ tests/test_hardware_governance.py | 348 +++++++++- tests/test_hardware_observability.py | 592 ++++++++++++++++++ tests/test_hardware_outcome.py | 172 +++++ tests/test_hardware_reading_store.py | 389 +++++++++++- tests/test_hardware_signal_path.py | 254 ++++++++ tests/test_hardware_stream.py | 199 +++++- tests/test_hardware_transport_contract.py | 395 +++++++++++- tests/test_journey_harness.py | 51 ++ tests/test_memory_and_storage.py | 2 +- tests/test_monitor_subsystem.py | 99 +++ tests/test_slash_command_router.py | 70 +++ tools/sync_fixtures.py | 29 +- 66 files changed, 6225 insertions(+), 372 deletions(-) create mode 100644 src/leapflow/dashboard/templates/hardware.yaml create mode 100644 src/leapflow/hardware/observability/__init__.py create mode 100644 src/leapflow/hardware/observability/digest.py create mode 100644 src/leapflow/hardware/observability/producer.py create mode 100644 src/leapflow/hardware/observability/series.py create mode 100644 src/leapflow/hardware/transports/mcp.py create mode 100644 tests/_fixtures/cassettes/r6_lifecycle/cassette-model-99a5ae1bc0719c4d.cassette.json create mode 100644 tests/_fixtures/cassettes/r6_lifecycle/cassette-model-fffcdbe5759f5a6b.cassette.json create mode 100644 tests/test_hardware_observability.py create mode 100644 tests/test_hardware_signal_path.py diff --git a/AGENTS.md b/AGENTS.md index e2090cc..acd6be6 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -8,13 +8,15 @@ This document is the LeapFlow engineering collaboration contract.

It is not only - **Budget-Constrained Recovery**: Turn-level deadlines, per-category limits, and a global recovery budget prevent infinite retry loops. Every recovery action has an explicit cost; exhaustion triggers a clean halt or user escalation. - **Recovery Strategy as Protocol**: Recovery strategies implement a `RecoveryStrategy` Protocol (`can_apply` + `decide`), registered by priority, composable, and extensible without modifying the coordinator. +## Plugin and Extension Rules + +The plugin subsystem is not a feature area — it is how the product is composed. Every capability the agent has, and every capability it can acquire at runtime, enters through it, so a mistake here changes what the agent is able to do rather than how well it does it. + +- **`leapflow.plugins` owns extension mechanics; `leapflow.tools` owns tool behaviour (MANDATORY)**: contracts (`protocol.py`), discovery/DI/assembly (`registry.py`), fiber lifecycle (`scoped_registry.py`), isolation (`sandbox/`), and distribution (`marketplace/`) live in the plugin package and nowhere else. The dependency direction is one-way and executable: plugin core must never import a tool module, and `tool_plugins/` is the single layer allowed to wrap one (`tests/test_architecture_contracts.py`). The relocated `leapflow.tools.{plugins,protocol,plugin_registry,scoped_registry,marketplace,sandbox}` paths must stay physically absent — a compatibility shim would split the registry's single source of truth and let two divergent registries coexist. +- **`ToolMetadata` is the single source of truth for a tool**: one declaration produces the provider schema, the handler mapping, and the PCD/capability metadata. `x_leapflow` is mandatory and must carry `category` and `risk_level`; a mutating tool declares `mutates_state` plus its approval/idempotency metadata; capability tags are declared, not inferred. Never hand-write a second schema, a parallel handler table, or a capability list beside it — the disclosure layer reads declared metadata first, and substring inference is a deprecated fallback that logs a warning. +- **Tool names are one global namespace, arbitrated first-wins and never silently**: the incumbent keeps the name and the challenger is recorded as a `CapabilityConflict` surfaced through `plugin_list`. Rejection is deliberately non-fatal so one colliding plugin cannot break assembly for every other plugin. Never overwrite a live handler or emit a duplicate schema to claim a name another plugin already owns. +- **Dependencies arrive late, through `bind_runtime`, and absence degrades rather than crashes**: plugins declare names in `dependencies` and receive matching services injected in provider→consumer topological order, independent of discovery order. A plugin module must not import a runtime service at module level, and must not perform I/O, network calls, or state mutation at import time — every module is required to be importable standalone. A handler whose dependency was never bound returns a structured refusal; it does not raise. +- **Lifecycle is a fiber, and cleanup is a scope (MANDATORY)**: every plugin instance lives under a `PluginFiber` (`PENDING → LOADING → ACTIVE → UNLOADING → DISPOSED`, with a `LOADING → FAILED → LOADING` retry path) whose `EffectScope` disposes registered effects LIFO, children before parents, idempotently and exception-safely. Anything a plugin registers process-globally — an interceptor on `registry.tool_pipeline`, an EventBus subscription, a background task — must be registered as an effect on that scope in the same change, or disable and reload leak it. Illegal transitions raise `IllegalStateTransition` instead of being silently corrected. +- **Hot-reload is safe because handlers are snapshotted per turn, not because reload is atomic**: each turn copies `dict(registry.tool_handlers)` at its start, so an in-flight turn finishes against the handlers it began with while `notify_mutation()`'s version bump invalidates the catalog cache for turns that start later. Reload re-imports through `importlib.util.spec_from_file_location` using the source path recorded as `__leapflow_plugin_path__` — never by mutating global `sys.path`, and never in a way that requires the plugin to be importable from the process's import path. +- **Plugin governance is cold-path (MANDATORY)**: fiber state, trust ledgers, usage statistics, health producers, advisors, proposal queues, and marketplace work must add no per-turn cost to the hot path. Trust is flushed to DuckDB only on level transitions (plus a final `atexit` flush), and usage samples stay in bounded deques. A governance feature that measurably slows an ordinary turn is a defect in the feature, not a cost to accept. +- **Plugin mutation is uniformly HIGH risk and never permanently granted**: any action whose `metadata.platform == "plugin_management"` is forced to `RiskLevel.HIGH` with `allow_permanent=False` in `security/risk.py` — defense-in-depth that holds even when caller metadata is wrong. Install, reload, rollback, enable, disable, and remove each build an `ActionDescriptor` and go through `ApprovalOrchestrator` per invocation. The single exemption is `plugin_reload` at `PRODUCTION` trust, which is earned evidence rather than a configured bypass. With no gate installed (in-process CLI binds none), every mutation is denied: code that can rewrite the agent's own composition must never be installable through an unguarded path. +- **Self-evolution is a governed pipeline, not a code-writing shortcut**: capability gap → proposal → generate → validate (syntax → structure → import/Protocol conformance) → compatibility assessment → approval → write → sandbox smoke → register at DRAFT → behavior tests → probation → trust accrual → verify, with quarantine and rollback as the failure path. An `INCOMPATIBLE` verdict is rejected before any file write; a failure at any later stage rolls back the fiber, the `sys.modules` entry, and the written file. Each next action comes from `AdaptiveEvolutionPolicy` reading structured requirement, risk, trust, and status — never from natural-language intent — and the autonomy level is configuration, so raising it is a deliberate operator decision rather than a code path. +- **Untrusted code is isolated before it is trusted**: `requires_sandbox` defaults to `True`; sandboxed plugins run in a subprocess over JSON-RPC with a bounded invoke timeout and receive no host-side runtime dependencies. Marketplace artifacts are verified by SHA-256 checksum and, when trusted pubkeys are configured, by Ed25519 signature over the canonical `name|version|entry_point|checksum_sha256` payload. Validation re-runs on the install path even for marketplace code that was already checked. +- **Plugins are process-global; sessions are not**: the registry is a daemon-wide singleton, so install, reload, disable, and remove change the capability set for every connected client at its next turn, and trust accrues from all of them. Any change to plugin state must be assessed against the concurrent-TUI contract — per-turn snapshots are the only isolation, and there is deliberately no per-workspace plugin set. +- **Self-capability answers come from the live registry, never from documentation**: when LeapFlow reports what it supports — plugins, self-evolution, hot reload, version management — the evidence is `plugin_list`'s live `capability_report` or an equivalent runtime registry read. If runtime introspection fails, state that the running state could not be verified; never infer a capability from README, design docs, or memory. +- **The plugin contract is published, so it changes with the code**: `docs/plugins/third_party_plugin_development.md` (interfaces, deployment, security model) and `docs/plugins/plugin_lifecycle_management.md` (lifecycle, governance matrix, enforcement status) are third-party-facing specifications whose tables state what the code does *today*. A change to a Protocol, a lifecycle transition, an approval rule, a config key, or an injectable dependency name updates them in the same change — and never promotes a roadmap entry to ENFORCED ahead of the wiring. + ## Path Tree, Configuration, and Secrets Rules - **Path tree is a product contract**: every LeapFlow-managed path must be declared by `PathLayout`, `ProfileLayout`, `CacheLayout`, or a child layout object.

For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **fixture_echo**(text) [capability_expand category: bridge]: Return the supplied text from a pre-built DSH package.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n\n## Recent Session Summary\n- [assistant] Installed the hermetic DSH plugin.\n- [user] Invoke fixture_echo with the text before restart.\n\n## Task Contract\n- Task ID: turn-2\n- Original user request: Invoke fixture_echo with the text before restart.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "Installed the hermetic DSH plugin." + }, + { + "role": "user", + "content": "Invoke fixture_echo with the text before restart.\nInvoke fixture_echo with the text before restart." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "fixture_echo" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"echo\": \"before restart\", \"execution_id\": \"\", \"idempotency_key\": \"\", \"execution_policy\": \"mutating_idempotent\", \"tool_call_id\": \"call_1\", \"execution_status\": \"completed\"}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **fixture_echo**(text) [capability_expand category: bridge]: Return the supplied text from a pre-built DSH package.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n\n## Recent Session Summary\n- [user] Invoke fixture_echo with the text after restart.\n\n## Task Contract\n- Task ID: turn-1\n- Original user request: Invoke fixture_echo with the text after restart.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "user", + "content": "Invoke fixture_echo with the text after restart.\nInvoke fixture_echo with the text after restart." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "fixture_echo" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"echo\": \"after restart\", \"execution_id\": \"\", \"idempotency_key\": \"\", \"execution_policy\": \"mutating_idempotent\", \"tool_call_id\": \"call_1\", \"execution_status\": \"completed\"}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

Envelope revisions, both driven by a falsified prediction --------------------------------------------------------- Two gaps were confirmed by experiment rather than by reasoning, and both changed what a stored delta means: - G-1 (E3-T0, ratio 100 where ~1 was predicted): bias is an absolute quantity and does not scale with the declared range, so span-normalisation made a tight-tolerance channel report a misleadingly small error. Envelope gains `tolerance`, and normalized_delta divides by it when declared. - G-2 (E2-T0, 95% convergence at 15s against a 2-tau budget of 10s, 12.3% residual): a single settling instant cannot describe an asymptotic approach. Envelope gains `settling_model` and `settling_tau_s`, with `effective_settling_s` giving 5*tau for first-order channels; record_command now waits on that rather than on a scalar. Both fields default to prior behaviour (`tolerance=0.0`, `settling_model="step"`), so hc.v0 declarations are unaffected and HC_VERSION does not move. The promotion threshold for hc.v1 is now met on evidence (four confirmed gaps across host, bench and driver classes), but bumping the version would force every existing declaration to be re-examined for an additive, optional change -- so the schema was extended instead. That call is worth a second look on review. New capability -------------- - Calibration: per-channel state, freshness and residual correction, with a store, a board section, and `leap hw` commands - Trust and readiness: a device that cannot be commanded is refused before a human is asked for consent, via `blocks_approval` -- prompting for permission to an action that will be denied teaches users to click through prompts - Replay and audit: device sessions can be replayed from recorded readings, and commands leave an audit trail - Transport discovery, an in-repo simulated transport, and a testing helper - r8_hardware journey with cassettes Security surface ---------------- `allow_permanent=False` is now enforced rather than advisory: the gate withholds session-wide bypass for actions whose risk forbids a permanent grant. Previously the flag was a suggestion no code checked. i18n ---- The calibration board section shipped eight English literals with no translation in any of the five non-English locales. `test_dashboard_i18n_static` caught it -- that test exists because five of seven boards once rendered English in every language while the older signal-key check stayed green. Tests: 3160 passed, 2 skipped, 1 xfailed (was 2708); journeys green including the new r8_hardware; ruff clean on new and modified files. --- .github/workflows/nightly-live.yaml | 217 +----

What "readiness" means in the Hardware Context Protocol + +A device is often unsafe or meaningless to command until it has completed an +initialization routine: a robot arm must be **homed** before its joints know +where they are; a depth camera must be **calibrated** before a captured frame +has any metric meaning. The Hardware Context Protocol (HCP) expresses this as a +**declared precondition on a writable channel**, not as procedural code and not +as a new field. + +The key architectural fact — enforced by +`tests/test_architecture_contracts.py` — is that `context.py` carries **no +transport, vendor, or upstream-standard concept**. Readiness is therefore +declared with the two primitives that already exist: + +- [`Envelope.requires_interlocks`](../../src/leapflow/hardware/context.py) — a + tuple of interlock ids that must hold before a write to that channel is + permitted. +- [`Interlock`](../../src/leapflow/hardware/context.py) — a deterministic + channel comparison (`channel_id` + `operator` + `value`) that points at a + **readiness channel** reporting whether the device has finished its init / + homing / calibration routine. + +There is **no** `DevicePhase`, `CalibrationState`, or `Procedure` type in the +current implementation. Readiness is nothing more than "a readable channel says +the device is ready, and a writable channel refuses to be commanded until it +does." + +--- + +## 2. How readiness is enforced (the write path) + +When a model calls `hw_actuate` / `hw_configure` / `hw_dispense`, the handler +`HardwareTools._write` (`src/leapflow/hardware/tools.py`) runs a fixed sequence +of feasibility checks **before** any approval prompt is shown, honoring the +platform rule that *feasibility precedes consent*: + +1. resolve device + channel, +2. channel is writable, +3. effect class matches the tool, +4. `hw_describe` was called first (when `require_describe_before_write`), +5. value lies inside the declared envelope, +6. rate limit (`max_rate`) is respected, +7. device is reachable, +8. **evaluate `requires_interlocks`** via `_failed_interlocks`, +9. build the `ActionDescriptor`, +10. (dry-run stops here — see §4), +11. **if any readiness interlock is unmet → hard stop `_not_ready`** (this + section), +12. approval gate, +13. execute against the transport. + +### 2.1 `not_ready` is a fail-closed hard stop + +If step 8 finds any unmet interlock, `_write` returns +`_not_ready(...)` **before consent is sought**. That refusal is built by the +single shared authority +[`build_readiness_failure`](../../src/leapflow/security/permission_failures.py), +so the engine and TUI report it identically. The payload is: + +```json +{ + "ok": false, + "device_id": "robot_arm_r1", + "channel_id": "joint_shoulder", + "failure_code": "not_ready", + "failure_class": "device_not_ready", + "blocks_approval": true, + "retryable": true, + "recoverability": "ready_state_required", + "error": "robot_arm_r1.joint_shoulder is not ready to command: 'homed' requires homed_state == True. Bring robot_arm_r1 to its declared ready state -- run its initialization / homing / calibration routine so every precondition above holds, confirm it by reading the source channel back, then re-issue the same command. No approval was requested because the command cannot succeed until the device is ready.", + "repair": { + "kind": "device_readiness", + "device_id": "robot_arm_r1", + "channel_id": "joint_shoulder", + "unmet": [ + { + "interlock_id": "homed", + "channel_id": "homed_state", + "operator": "eq", + "value": true, + "description": "The arm must complete homing before any joint is commanded.", + "declared": true + } + ] + }, + "side_effect_state": "none" +} +``` + +Properties that matter: + +- **`blocks_approval: true`** makes it a hard stop under + `is_permission_hard_stop_payload`: the turn surfaces the deterministic repair + instruction instead of giving the LLM another chance to retry or invent a way + around it. No approval prompt is ever shown. +- **`retryable: true`** because the *identical* command becomes feasible once + the preconditions hold — the fix is to make the device ready, not to change + the command. +- **`side_effect_state: "none"`** — nothing reached the device. +- The **`error`** prose and the machine-readable **`repair.unmet`** array carry + the same information, so both a human and an automated caller know exactly + which precondition failed and on which source channel to confirm it. + +### 2.2 Readiness fails closed on every uncertainty + +`_failed_interlocks` treats a missing interlock, an unreadable source channel, +or a source read that raises **all** as unsatisfied: "cannot check" and "not +satisfied" carry the same consequence. An interlock named on a channel's +`requires_interlocks` but absent from the device's `interlocks` list is reported +with `"declared": false`, because the repair differs (fix the declaration, not +the device). The risk classifier keeps its own interlock hardline as +defense-in-depth for any descriptor built outside this path. + +--- + +## 3. Authorizing calibration with `verified_by` + +Readiness (§2) answers "has the device finished its routine?" A separate +question is "does a human vouch for this device declaration at all?" — which is +what authorizes writes in the first place. That is +[`ContextProvenance.verified_by`](../../src/leapflow/hardware/context.py) and +the **V7 admission rule** in `registry.py`. + +- `ContextProvenance.is_verified` is simply `bool(verified_by.strip())`. +- Under the default policy `unverified_context_policy = "deny_write"` + (`HardwareSettings`), an **unverified** context has **every writable channel + demoted to read-only** at admission time (rule V7). A subsequent write then + fails with `channel_not_writable`, not `not_ready` — the two are distinct + causes. + +Verification is stored **out of band** from the declaration on purpose: the +person who confirms a device must not edit the file they are confirming, or the +confirmation would be self-attested. The YAML provider reads a sibling +`verified.json` mapping `device_id → verifier` and stamps +`provenance.verified_by` on load (`YamlContextProvider._apply_verification`). + +```json +// verified.json (sibling of the devices directory) +{ + "depth_cam_d1": "alice@lab (intrinsics+hand-eye checked 2026-08-30)" +} +``` + +For calibration-bearing devices this doubles as the **calibration +authorization**: a device whose captured data is only trustworthy after +calibration should ship **unverified**, so its writable channels stay demoted +until a human records — in `verified.json` — that calibration was performed and +checked. Set `verified_by` and the writable channels are admitted; leave it +empty and they are not. + +--- + +## 4. Previewing with `dry_run` + +Every write tool accepts `dry_run: true` +(`hw_actuate` / `hw_configure` / `hw_dispense`). A dry run executes **all** +feasibility checks in §2 (resolution, writability, effect class, describe, +envelope, rate, reachability, **and interlocks**), builds the approval +descriptor, and then **stops without seeking consent or touching the device**. +It is safe against an irreversible channel because nothing is written; the +result is a `WriteOutcome` with `preview: true` and `side_effect_state: "none"`. + +The returned `plan` reports the command that *would* be issued together with the +outcome of every pre-consent check — including readiness: + +```json +{ + "device_id": "robot_arm_r1", + "channel_id": "joint_shoulder", + "ok": false, + "side_effect_state": "none", + "preview": true, + "failure_code": "interlocks_unsatisfied", + "error": "Interlocks ['homed'] are not satisfied for robot_arm_r1.joint_shoulder, so the real command would be refused. Restore the interlock conditions before commanding it.", + "plan": { + "value_in_envelope": true, + "interlocks_satisfied": false, + "interlocks_failed": ["homed"] + } +} +``` + +`plan.ok` is `true` only when the value is inside the envelope **and** every +interlock holds — the same two conditions that would otherwise let it reach +approval. This makes `dry_run` the recommended way to confirm both intent and +readiness before committing an irreversible physical effect. + +> **Dispense note:** `effect=dispense` is treated as an irreversible external +> output regardless of the channel's `reversible` flag — a substance that has +> left the device cannot be un-dispensed. Consequently, dispense writes +> **never** receive session-level or profile-level reusable consent +> (`allow_permanent` is always `false`); each dispense command is confirmed +> individually. + +--- + +## 5. Complete examples + +Device declarations are YAML files whose structure mirrors +`HardwareContext.to_dict()` / `from_mapping`. `hc_version` must be `hc.v0`. +`Interlock.operator` is one of `eq` / `ne` / `lt` / `le` / `gt` / `ge` +(default `eq`); `value` defaults to `true`. + +### 5.1 Robot arm homing + +A `homed_state` readiness channel reports whether homing has completed; a motion +channel declares `requires_interlocks: [homed]`, so a joint cannot be commanded +until the arm is homed. + +```yaml +hc_version: hc.v0 +device_id: robot_arm_r1 +display_name: Bench robot arm R1 +vendor: ExampleRobotics +model: RA-6 +location: bench-3 +halt_supported: true +notes: >- + Six-axis arm.

Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-5\n- Original user request: Preview an actuate of bench_r8 setpoint to 55, dry run only.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "Read the setpoint channel." + }, + { + "role": "user", + "content": "Actuate the bench_r8 setpoint to 60.\nConfigure the bench_r8 homed channel to true to complete homing." + }, + { + "role": "assistant", + "content": "[Called: hw_configure]\nHomed the device; the readiness gate is now satisfied." + }, + { + "role": "user", + "content": "Preview an actuate of bench_r8 setpoint to 55, dry run only.\nPreview an actuate of bench_r8 setpoint to 55, dry run only." + } + ], + "tools": [ + "capability_expand", + "code_intel", + "code_search", + "config_get", + "config_list", + "env_info", + "file_find", + "file_list", + "file_read", + "git_query", + "hw_actuate", + "hw_configure", + "hw_describe", + "hw_dispense", + "hw_estop", + "hw_list", + "hw_read", + "hw_status", + "lint_check", + "memory_search", + "plugin_list", + "plugin_propose", + "plugin_status", + "plugin_versions", + "repo_map", + "research_note", + "schedule_reentry", + "session_list", + "skill_view", + "skills_list", + "terminal_list", + "terminal_read", + "test_run", + "text_search", + "time_get", + "web_fetch" + ] + }, + "responses": [ + { + "status": 200, + "content_type": "application/json", + "body": "{\"id\": \"chatcmpl-cassette\", \"object\": \"chat.completion\", \"model\": \"cassette-model\", \"choices\": [{\"index\": 0, \"message\": {\"role\": \"assistant\", \"content\": \"\", \"tool_calls\": [{\"id\": \"call_1\", \"type\": \"function\", \"function\": {\"name\": \"hw_actuate\", \"arguments\": \"{\\\"device_id\\\": \\\"bench_r8\\\", \\\"channel_id\\\": \\\"setpoint\\\", \\\"value\\\": 55.0, \\\"dry_run\\\": true}\"}}]}, \"finish_reason\": \"tool_calls\"}], \"usage\": {\"prompt_tokens\": 64, \"completion_tokens\": 16, \"total_tokens\": 80}}" + } + ] +} diff --git a/tests/_fixtures/cassettes/r8_hardware/cassette-model-583815519f06198e.cassette.json b/tests/_fixtures/cassettes/r8_hardware/cassette-model-583815519f06198e.cassette.json new file mode 100644 index 0000000..87335e0 --- /dev/null +++ b/tests/_fixtures/cassettes/r8_hardware/cassette-model-583815519f06198e.cassette.json @@ -0,0 +1,71 @@ +{ + "fingerprint": "583815519f06198e3d98103203ca443426028bfa182eb4a288a6cad41ae3ecac", + "note": "captured in seed mode", + "request": { + "model": "cassette-model", + "stream": false, + "messages": [ + { + "role": "system", + "content": "You are LeapFlow, an intelligent assistant that can both converse naturally and take real actions on the user's computer.\n\n## Capabilities\nThe tool index below lists **every** registered tool by name and a one-line summary — this is the complete\ncapability contract; nothing else exists. Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-2\n- Original user request: Read the current value of the setpoint channel on bench_r8.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "user", + "content": "List the connected hardware devices, then describe bench_r8 in full." + }, + { + "role": "assistant", + "content": "[Called: hw_list]\n[Called: hw_describe]\nDiscovered the simulated bench and read its channel limits." + }, + { + "role": "user", + "content": "Read the current value of the setpoint channel on bench_r8.\nRead the current value of the setpoint channel on bench_r8." + } + ], + "tools": [ + "capability_expand", + "code_intel", + "code_search", + "config_get", + "config_list", + "env_info", + "file_find", + "file_list", + "file_read", + "git_query", + "hw_actuate", + "hw_configure", + "hw_describe", + "hw_dispense", + "hw_estop", + "hw_list", + "hw_read", + "hw_status", + "lint_check", + "memory_search", + "plugin_list", + "plugin_propose", + "plugin_status", + "plugin_versions", + "repo_map", + "research_note", + "schedule_reentry", + "session_list", + "skill_view", + "skills_list", + "terminal_list", + "terminal_read", + "test_run", + "text_search", + "time_get", + "web_fetch" + ] + }, + "responses": [ + { + "status": 200, + "content_type": "application/json", + "body": "{\"id\": \"chatcmpl-cassette\", \"object\": \"chat.completion\", \"model\": \"cassette-model\", \"choices\": [{\"index\": 0, \"message\": {\"role\": \"assistant\", \"content\": \"\", \"tool_calls\": [{\"id\": \"call_1\", \"type\": \"function\", \"function\": {\"name\": \"hw_read\", \"arguments\": \"{\\\"device_id\\\": \\\"bench_r8\\\", \\\"channel_id\\\": \\\"setpoint\\\"}\"}}]}, \"finish_reason\": \"tool_calls\"}], \"usage\": {\"prompt_tokens\": 64, \"completion_tokens\": 16, \"total_tokens\": 80}}" + } + ] +} diff --git a/tests/_fixtures/cassettes/r8_hardware/cassette-model-6e8e063572cdc304.cassette.json b/tests/_fixtures/cassettes/r8_hardware/cassette-model-6e8e063572cdc304.cassette.json new file mode 100644 index 0000000..8931522 --- /dev/null +++ b/tests/_fixtures/cassettes/r8_hardware/cassette-model-6e8e063572cdc304.cassette.json @@ -0,0 +1,75 @@ +{ + "fingerprint": "6e8e063572cdc304eeeef7b549b8f1e08ee65f58a482c9f80a2a36181a52dd6a", + "note": "captured in seed mode", + "request": { + "model": "cassette-model", + "stream": false, + "messages": [ + { + "role": "system", + "content": "You are LeapFlow, an intelligent assistant that can both converse naturally and take real actions on the user's computer.\n\n## Capabilities\nThe tool index below lists **every** registered tool by name and a one-line summary — this is the complete\ncapability contract; nothing else exists. Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-4\n- Original user request: Configure the bench_r8 homed channel to true to complete homing.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "Discovered the simulated bench and read its channel limits." + }, + { + "role": "user", + "content": "Read the current value of the setpoint channel on bench_r8." + }, + { + "role": "assistant", + "content": "[Called: hw_read]\nRead the setpoint channel." + }, + { + "role": "user", + "content": "Actuate the bench_r8 setpoint to 60.\nConfigure the bench_r8 homed channel to true to complete homing.\nConfigure the bench_r8 homed channel to true to complete homing." + } + ], + "tools": [ + "capability_expand", + "code_intel", + "code_search", + "config_get", + "config_list", + "env_info", + "file_find", + "file_list", + "file_read", + "git_query", + "hw_actuate", + "hw_configure", + "hw_describe", + "hw_dispense", + "hw_estop", + "hw_list", + "hw_read", + "hw_status", + "lint_check", + "memory_search", + "plugin_list", + "plugin_propose", + "plugin_status", + "plugin_versions", + "repo_map", + "research_note", + "schedule_reentry", + "session_list", + "skill_view", + "skills_list", + "terminal_list", + "terminal_read", + "test_run", + "text_search", + "time_get", + "web_fetch" + ] + }, + "responses": [ + { + "status": 200, + "content_type": "application/json", + "body": "{\"id\": \"chatcmpl-cassette\", \"object\": \"chat.completion\", \"model\": \"cassette-model\", \"choices\": [{\"index\": 0, \"message\": {\"role\": \"assistant\", \"content\": \"\", \"tool_calls\": [{\"id\": \"call_1\", \"type\": \"function\", \"function\": {\"name\": \"hw_configure\", \"arguments\": \"{\\\"device_id\\\": \\\"bench_r8\\\", \\\"channel_id\\\": \\\"homed\\\", \\\"value\\\": true}\"}}]}, \"finish_reason\": \"tool_calls\"}], \"usage\": {\"prompt_tokens\": 64, \"completion_tokens\": 16, \"total_tokens\": 80}}" + } + ] +} diff --git a/tests/_fixtures/cassettes/r8_hardware/cassette-model-7bb12f60a94312b7.cassette.json b/tests/_fixtures/cassettes/r8_hardware/cassette-model-7bb12f60a94312b7.cassette.json new file mode 100644 index 0000000..fa29389 --- /dev/null +++ b/tests/_fixtures/cassettes/r8_hardware/cassette-model-7bb12f60a94312b7.cassette.json @@ -0,0 +1,87 @@ +{ + "fingerprint": "7bb12f60a94312b7e4956db0187e89ba1654d52a2e6956fb7e97171bf46c5121", + "note": "captured in seed mode", + "request": { + "model": "cassette-model", + "stream": false, + "messages": [ + { + "role": "system", + "content": "You are LeapFlow, an intelligent assistant that can both converse naturally and take real actions on the user's computer.\n\n## Capabilities\nThe tool index below lists **every** registered tool by name and a one-line summary — this is the complete\ncapability contract; nothing else exists. Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-2\n- Original user request: Read the current value of the setpoint channel on bench_r8.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "user", + "content": "List the connected hardware devices, then describe bench_r8 in full." + }, + { + "role": "assistant", + "content": "[Called: hw_list]\n[Called: hw_describe]\nDiscovered the simulated bench and read its channel limits." + }, + { + "role": "user", + "content": "Read the current value of the setpoint channel on bench_r8.\nRead the current value of the setpoint channel on bench_r8." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "hw_read" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"reading\": {\"device_id\": \"bench_r8\", \"channel_id\": \"setpoint\", \"value\": 50.0, \"quantity\": \"temperature\", \"unit\": \"C\", \"observed_at\": , \"sequence\": 1, \"quality\": \"ok\"}, \"execution_id\": \"\", \"idempotency_key\": \"\", \"execution_policy\": \"read_only\", \"tool_call_id\": \"call_1\", \"execution_status\": \"completed\"}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-6\n- Original user request: Actuate the bench_r8 setpoint to 65.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "[Called: hw_configure]\nHomed the device; the readiness gate is now satisfied." + }, + { + "role": "user", + "content": "Preview an actuate of bench_r8 setpoint to 55, dry run only." + }, + { + "role": "assistant", + "content": "[Called: hw_actuate]\nDry run confirmed the setpoint command is feasible after homing." + }, + { + "role": "user", + "content": "Actuate the bench_r8 setpoint to 65.\nActuate the bench_r8 setpoint to 65." + } + ], + "tools": [ + "capability_expand", + "code_intel", + "code_search", + "config_get", + "config_list", + "env_info", + "file_find", + "file_list", + "file_read", + "git_query", + "hw_actuate", + "hw_configure", + "hw_describe", + "hw_dispense", + "hw_estop", + "hw_list", + "hw_read", + "hw_status", + "lint_check", + "memory_search", + "plugin_list", + "plugin_propose", + "plugin_status", + "plugin_versions", + "repo_map", + "research_note", + "schedule_reentry", + "session_list", + "skill_view", + "skills_list", + "terminal_list", + "terminal_read", + "test_run", + "text_search", + "time_get", + "web_fetch" + ] + }, + "responses": [ + { + "status": 200, + "content_type": "application/json", + "body": "{\"id\": \"chatcmpl-cassette\", \"object\": \"chat.completion\", \"model\": \"cassette-model\", \"choices\": [{\"index\": 0, \"message\": {\"role\": \"assistant\", \"content\": \"\", \"tool_calls\": [{\"id\": \"call_1\", \"type\": \"function\", \"function\": {\"name\": \"hw_actuate\", \"arguments\": \"{\\\"device_id\\\": \\\"bench_r8\\\", \\\"channel_id\\\": \\\"setpoint\\\", \\\"value\\\": 65.0}\"}}]}, \"finish_reason\": \"tool_calls\"}], \"usage\": {\"prompt_tokens\": 64, \"completion_tokens\": 16, \"total_tokens\": 80}}" + } + ] +} diff --git a/tests/_fixtures/cassettes/r8_hardware/cassette-model-967bf7560b3aa81a.cassette.json b/tests/_fixtures/cassettes/r8_hardware/cassette-model-967bf7560b3aa81a.cassette.json new file mode 100644 index 0000000..4386f57 --- /dev/null +++ b/tests/_fixtures/cassettes/r8_hardware/cassette-model-967bf7560b3aa81a.cassette.json @@ -0,0 +1,91 @@ +{ + "fingerprint": "967bf7560b3aa81a69701dbd4c98fbf1995b397fb7faf6d92c2f779e9da7a0aa", + "note": "captured in seed mode", + "request": { + "model": "cassette-model", + "stream": false, + "messages": [ + { + "role": "system", + "content": "You are LeapFlow, an intelligent assistant that can both converse naturally and take real actions on the user's computer.\n\n## Capabilities\nThe tool index below lists **every** registered tool by name and a one-line summary — this is the complete\ncapability contract; nothing else exists.

Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-6\n- Original user request: Actuate the bench_r8 setpoint to 65.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "[Called: hw_configure]\nHomed the device; the readiness gate is now satisfied." + }, + { + "role": "user", + "content": "Preview an actuate of bench_r8 setpoint to 55, dry run only." + }, + { + "role": "assistant", + "content": "[Called: hw_actuate]\nDry run confirmed the setpoint command is feasible after homing." + }, + { + "role": "user", + "content": "Actuate the bench_r8 setpoint to 65.\nActuate the bench_r8 setpoint to 65." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "hw_actuate" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"device_id\": \"bench_r8\", \"channel_id\": \"setpoint\", \"side_effect_state\": \"committed\", \"settled\": true, \"execution_id\": \"\", \"idempotency_key\": \"\", \"execution_policy\": \"external_side_effect\", \"tool_call_id\": \"call_1\", \"execution_status\": \"completed\"}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-5\n- Original user request: Preview an actuate of bench_r8 setpoint to 55, dry run only.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "Read the setpoint channel." + }, + { + "role": "user", + "content": "Actuate the bench_r8 setpoint to 60.\nConfigure the bench_r8 homed channel to true to complete homing." + }, + { + "role": "assistant", + "content": "[Called: hw_configure]\nHomed the device; the readiness gate is now satisfied." + }, + { + "role": "user", + "content": "Preview an actuate of bench_r8 setpoint to 55, dry run only.\nPreview an actuate of bench_r8 setpoint to 55, dry run only." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "hw_actuate" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"kind\": \"\", \"truncated\": true, \"original_chars\": 888, \"budget_chars\": 819}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-4\n- Original user request: Configure the bench_r8 homed channel to true to complete homing.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "Discovered the simulated bench and read its channel limits." + }, + { + "role": "user", + "content": "Read the current value of the setpoint channel on bench_r8." + }, + { + "role": "assistant", + "content": "[Called: hw_read]\nRead the setpoint channel." + }, + { + "role": "user", + "content": "Actuate the bench_r8 setpoint to 60.\nConfigure the bench_r8 homed channel to true to complete homing.\nConfigure the bench_r8 homed channel to true to complete homing." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "hw_configure" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"device_id\": \"bench_r8\", \"channel_id\": \"homed\", \"side_effect_state\": \"committed\", \"settled\": true, \"execution_id\": \"\", \"idempotency_key\": \"\", \"execution_policy\": \"external_side_effect\", \"tool_call_id\": \"call_1\", \"execution_status\": \"completed\"}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n\n## Recent Session Summary\n- [user] List the connected hardware devices, then describe bench_r8 in full.\n\n## Task Contract\n- Task ID: turn-1\n- Original user request: List the connected hardware devices, then describe bench_r8 in full.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "user", + "content": "List the connected hardware devices, then describe bench_r8 in full.\nList the connected hardware devices, then describe bench_r8 in full." + } + ], + "tools": [ + "capability_expand", + "code_intel", + "code_search", + "config_get", + "config_list", + "env_info", + "file_find", + "file_list", + "file_read", + "git_query", + "hw_describe", + "hw_list", + "hw_read", + "hw_status", + "lint_check", + "memory_search", + "plugin_list", + "plugin_propose", + "plugin_status", + "plugin_versions", + "repo_map", + "research_note", + "schedule_reentry", + "session_list", + "skill_view", + "skills_list", + "terminal_list", + "terminal_read", + "test_run", + "text_search", + "time_get", + "web_fetch" + ] + }, + "responses": [ + { + "status": 200, + "content_type": "application/json", + "body": "{\"id\": \"chatcmpl-cassette\", \"object\": \"chat.completion\", \"model\": \"cassette-model\", \"choices\": [{\"index\": 0, \"message\": {\"role\": \"assistant\", \"content\": \"\", \"tool_calls\": [{\"id\": \"call_1\", \"type\": \"function\", \"function\": {\"name\": \"hw_list\", \"arguments\": \"{}\"}}]}, \"finish_reason\": \"tool_calls\"}], \"usage\": {\"prompt_tokens\": 64, \"completion_tokens\": 16, \"total_tokens\": 80}}" + } + ] +} diff --git a/tests/_fixtures/cassettes/r8_hardware/cassette-model-ce9d6cca477b8de6.cassette.json b/tests/_fixtures/cassettes/r8_hardware/cassette-model-ce9d6cca477b8de6.cassette.json new file mode 100644 index 0000000..3e4cbe8 --- /dev/null +++ b/tests/_fixtures/cassettes/r8_hardware/cassette-model-ce9d6cca477b8de6.cassette.json @@ -0,0 +1,87 @@ +{ + "fingerprint": "ce9d6cca477b8de60516f04ea88312c8ae79676f71f5068dc5079f8529a71b37", + "note": "captured in seed mode", + "request": { + "model": "cassette-model", + "stream": false, + "messages": [ + { + "role": "system", + "content": "You are LeapFlow, an intelligent assistant that can both converse naturally and take real actions on the user's computer.\n\n## Capabilities\nThe tool index below lists **every** registered tool by name and a one-line summary — this is the complete\ncapability contract; nothing else exists.

Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n\n## Recent Session Summary\n- [user] List the connected hardware devices, then describe bench_r8 in full.\n\n## Task Contract\n- Task ID: turn-1\n- Original user request: List the connected hardware devices, then describe bench_r8 in full.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "user", + "content": "List the connected hardware devices, then describe bench_r8 in full.\nList the connected hardware devices, then describe bench_r8 in full." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "hw_list" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"devices\": [{\"device_id\": \"bench_r8\", \"display_name\": \"R8 Simulated Bench\", \"location\": \"journey-lab\", \"channels\": 3, \"writable\": 2, \"streaming\": 1, \"quantities\": [\"state.homed\", \"temperature\"], \"verified\": true, \"halt_supported\": true}], \"count\": 1, \"hint\": \"Call hw_describe(device_id) for channel limits before commanding a device.\", \"execution_id\": \"\", \"idempotency_key\": \"\", \"execution_policy\": \"read_only\", \"tool_call_id\": \"call_1\", \"execution_status\": \"completed\"}", + "tool_result": true + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "hw_describe" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"kind\": \"\", \"truncated\": true, \"original_chars\": 846, \"budget_chars\": 819}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

Only a subset is directly callable this turn (via native tool calling,\nnot a JSON block in your reply). If you need a tool from the index that is not yet callable, call\n`capability_expand` with its category name first — the matching tools become callable immediately after.\nWhen the user asks what LeapFlow itself supports, whether it supports plugins, or which runtime capabilities\nare available, use the live capability evidence exposed by `plugin_list` before making capability claims; report\nconfiguration-dependent or unavailable capabilities as limitations instead of inferring from documentation.\n- **text_search**(text, pattern): Search for a regex pattern in text.\n- **text_replace**(text, old, new, count) [capability_expand category: write]: Replace occurrences of a substring in text.\n- **time_get**(): Get current date and time.\n- **env_info**(): Get system environment information (OS, Python version, cwd).\n- **skills_list**(query, category, source): List available learned skills. Use when user asks about capabilities or you need a specific skill.\n- **skill_view**(name): View the full content of a specific skill document.\n- **code_intel**(path, operation): Precise document symbols (outline) for a source file: classes, functions, and methods with line ranges. Python uses an exact AST parse; other languages use a keyword-prefix scan. Prefer over file_read mode=symbols for accurate navigation before editing. Read-only.\n- **repo_map**(path): Compact project orientation for a repository root: languages, detected test/lint commands, top-level structure, entry points, manifest, and VCS branch. Call this first when entering an unfamiliar codebase. Read-only.\n- **scm_sync**(action, cwd, remote, pull_ref, push_ref, timeout) [capability_expand category: scm]: Run a typed git SCM action. Use this instead of shell_run for git pull/push/status. For 'pull origin main then push', set action='pull_then_push', remote='origin', pull_ref='main', and omit push_ref so LeapFlow pushes the current local branch.\n- **git_query**(action, cwd, ref, path, staged, max_count, stat): Read-only structured git inspection: action=diff|log|status|branch|show. Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n## Task Contract\n- Task ID: turn-3\n- Original user request: Actuate the bench_r8 setpoint to 60.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "assistant", + "content": "[Called: hw_describe]\nDiscovered the simulated bench and read its channel limits." + }, + { + "role": "user", + "content": "Read the current value of the setpoint channel on bench_r8." + }, + { + "role": "assistant", + "content": "[Called: hw_read]\nRead the setpoint channel." + }, + { + "role": "user", + "content": "Actuate the bench_r8 setpoint to 60.\nActuate the bench_r8 setpoint to 60." + } + ], + "tools": [ + "capability_expand", + "code_intel", + "code_search", + "config_get", + "config_list", + "env_info", + "file_find", + "file_list", + "file_read", + "git_query", + "hw_actuate", + "hw_configure", + "hw_describe", + "hw_dispense", + "hw_estop", + "hw_list", + "hw_read", + "hw_status", + "lint_check", + "memory_search", + "plugin_list", + "plugin_propose", + "plugin_status", + "plugin_versions", + "repo_map", + "research_note", + "schedule_reentry", + "session_list", + "skill_view", + "skills_list", + "terminal_list", + "terminal_read", + "test_run", + "text_search", + "time_get", + "web_fetch" + ] + }, + "responses": [ + { + "status": 200, + "content_type": "application/json", + "body": "{\"id\": \"chatcmpl-cassette\", \"object\": \"chat.completion\", \"model\": \"cassette-model\", \"choices\": [{\"index\": 0, \"message\": {\"role\": \"assistant\", \"content\": \"\", \"tool_calls\": [{\"id\": \"call_1\", \"type\": \"function\", \"function\": {\"name\": \"hw_actuate\", \"arguments\": \"{\\\"device_id\\\": \\\"bench_r8\\\", \\\"channel_id\\\": \\\"setpoint\\\", \\\"value\\\": 60.0}\"}}]}, \"finish_reason\": \"tool_calls\"}], \"usage\": {\"prompt_tokens\": 64, \"completion_tokens\": 16, \"total_tokens\": 80}}" + } + ] +} diff --git a/tests/_fixtures/cassettes/r8_hardware/cassette-model-e8bdc4c32c5748e3.cassette.json b/tests/_fixtures/cassettes/r8_hardware/cassette-model-e8bdc4c32c5748e3.cassette.json new file mode 100644 index 0000000..4de2b01 --- /dev/null +++ b/tests/_fixtures/cassettes/r8_hardware/cassette-model-e8bdc4c32c5748e3.cassette.json @@ -0,0 +1,75 @@ +{ + "fingerprint": "e8bdc4c32c5748e3de7a0fc95b4ecb4c592894ab4d56d4f17160a050aedb8b67", + "note": "captured in seed mode", + "request": { + "model": "cassette-model", + "stream": false, + "messages": [ + { + "role": "system", + "content": "You are LeapFlow, an intelligent assistant that can both converse naturally and take real actions on the user's computer.\n\n## Capabilities\nThe tool index below lists **every** registered tool by name and a one-line summary — this is the complete\ncapability contract; nothing else exists.

Prefer over shell_run for reading repo state — output is clipped, redacted, and log/branch are parsed into structured fields. Use scm_sync for pull/push.\n- **git_write**(action, cwd, message, stage_all, name, ref, create) [capability_expand category: scm]: Mutating git actions: action=commit (message, stage_all), branch (create+switch), checkout (switch; create=true for -b). Approval-gated. Use scm_sync for pull/push and git_query for reads.\n- **test_run**(command, cwd, timeout): Run the project's test suite and return structured results (framework, passed/failed counts, failing tests). Auto-detects the runner (pytest/npm/go/cargo) or uses a configured/explicit command; executes via the governed shell. ok=true means the runner executed — see 'success' for pass/fail.\n- **lint_check**(command, cwd, timeout): Run the project's linter and return a structured clean/issue result. Auto-detects the linter (ruff/eslint/go vet/clippy) or uses a configured/explicit command; executes via the governed shell. ok=true means the linter ran — see 'clean'.\n- **file_list**(path, pattern, depth): List files and directories at a given path. Use depth=1 or depth=2 to get a recursive tree in one call instead of listing each sub-directory separately.\n- **file_read**(path, max_lines, start_line, max_chars, mode): Read text file content with adaptive context governance. For large or unfamiliar files, prefer mode='outline' or mode='symbols' first, then use mode='raw' with start_line/max_lines for the specific range you actually need. For LeapFlow's own settings, use config_list / config_get / config_set — its config files are outside the workspace and not readable here.\n- **file_write**(path, content, mode) [capability_expand category: write]: Write content to a file (overwrite or append).\n- **code_search**(pattern, patterns, path, glob, ignore_case, multiline, max_results, context_lines): Search file CONTENTS by regex pattern across a directory tree (ripgrep-backed). Requires a regex pattern. NOT for listing or browsing directory contents — use file_list for that. Prefer this over shell_run grep: faster, skips VCS/dependency/build dirs, and returns structured path:line:column matches. Batch related lookups into ONE call via `patterns` (OR-combined, single pass) instead of issuing several separate searches. Use file_read for the surrounding context of a hit.\n- **file_find**(glob, path, max_results): Find files by a recursive glob pattern under a base path (e.g. '**/test_*.py' or '*.md'). Prefer this over shell_run find; skips VCS/dependency/build dirs.\n- **edit_file**(path, edits, dry_run, diff) [capability_expand category: write]: Apply targeted, anchored search-replace edits to an EXISTING text file (use file_write to create/overwrite). Each edit is {original_text, new_text, replace_all?}; original_text must match exactly and uniquely (or set replace_all) — a non-unique or missing anchor is rejected so files are never corrupted. Set dry_run to preview. Alternatively pass a unified 'diff' to apply its hunks as anchored edits. Far cheaper and safer than rewriting a whole file.\n- **shell_run**(command, cwd, timeout) [capability_expand category: shell]: Execute a one-shot shell command with timeout protection. Runs in the active workspace; paths resolving outside it are refused. Reach for a structured tool first when one fits — web_fetch for anything over HTTP(S), git_query/scm_sync for git, code_search/file_find/file_read for the repo, config_get/config_set for LeapFlow's own settings — because those report typed results, while a failed shell command can only be diagnosed from its exit code and stderr. Every shell run counts as an external side effect, so a failure stops the rest of the batch and is not retried automatically.\n- **terminal_open**(command, cwd, shell) [capability_expand category: terminal]: Open a PERSISTENT shell session (REPL/dev server/watch), returning a session_id for terminal_send/read/close. Disabled unless tools.terminal_session_enabled is set. For one-shot commands use shell_run instead.\n- **terminal_send**(session_id, input, wait) [capability_expand category: terminal]: Send a line of input to a persistent terminal session and return output captured shortly after.\n- **terminal_read**(session_id, wait): Drain buffered output from a persistent terminal session (optionally waiting briefly first).\n- **terminal_close**(session_id) [capability_expand category: terminal]: Terminate a persistent terminal session and release its process group.\n- **terminal_list**(): List active persistent terminal sessions.\n- **config_list**(category, limit): List LeapFlow's own writable settings (model, provider, daemon, memory, perception, gateway, …) with current values. Use this to discover the exact key before changing anything. Optionally narrow by `category`. This is the only correct way to inspect LeapFlow configuration — never read config files from disk.\n- **config_get**(key): Read one LeapFlow setting by key (e.g. 'llm.model', 'daemon.log_level'), returning its current value, type, scopes, and whether a change needs a daemon restart. Never read LeapFlow config files from disk — use this.\n- **config_set**(key, value, scope) [capability_expand category: config]: Change one LeapFlow setting by key, e.g. switch the model with key='llm.model'. Values are validated and coerced; credentials are stored in the vault automatically. Call config_list or config_get first if unsure of the key. The result states whether a `leap daemon restart` is required. Never edit LeapFlow config files directly.\n- **web_fetch**(url, select, timeout, max_bytes): Read a URL over HTTP(S) and get back extracted, context-sized content: parsed JSON for API endpoints, readable text plus links for web pages. Use this for anything on the internet — prices, docs, releases, articles — instead of running curl through shell_run: it reports real HTTP status codes, retries rate limits on its own, and is a plain read so a retry is always safe. For JSON APIs pass `select` with a dotted path (e.g. 'chart.result.0.meta') to return just that part instead of the whole payload.\n- **memory_search**(query, limit): Search agent memory for relevant past experiences, observations, and facts.\n- **memory_add**(content, kind) [capability_expand category: write]: Store a new observation or insight in memory for future reference.\n- **research_note**(kind, text): Record a compact, structured note about the current task's state so it survives context compression on long / multi-step tasks. Use for durable findings, open questions still to resolve, decisions / excluded paths, and the immediate next step. One concise sentence per note.\n- **capability_expand**(category): Fetch the full callable schema for every tool in a capability category (e.g. 'hub', 'gateway', 'desktop', 'delegate', 'file', 'memory', 'skill'). The compact tool index always lists every registered tool by name and a one-line summary, but only a static low-risk subset is directly callable each turn. If you need a tool from the index that is not yet callable, call capability_expand with its category first; the matching tools become callable in this turn. Never invent a tool name — expand the category instead.\n- **delegate_task**(goal, context) [capability_expand category: delegate]: Delegate a complex sub-task to an isolated subagent. The subagent gets a fresh context and restricted tool access. Use when a task is self-contained and can be solved independently.\n- **schedule_reentry**(kind, reason, delay_seconds, event_match, max_reentries, deadline_seconds): Register a re-entry so this task can resume later from its current orientation (findings / open questions / next step). Use when work must pause and continue after a delay (kind=time) or when a matching platform event arrives (kind=event), instead of finishing now. The research-ledger state is carried over automatically.\n- **hub_push**(skill_name, visibility, version) [capability_expand category: hub]: Push a local skill to the ModelScope Hub for sharing or backup.\n- **hub_pull**(repo_id, version) [capability_expand category: hub]: Pull a skill from the ModelScope Hub to install locally.\n- **hub_search**(query) [capability_expand category: hub]: Search for skills on the Hub by keyword or description.\n- **hub_sync**(mode, dry_run) [capability_expand category: hub]: Preview or execute sync between local skills and Hub.\n- **platform_action**(platform, action, payload, backend_kind) [capability_expand category: gateway]: Execute an exact registered business action on an external platform through LeapFlow's App Connector layer. Actions must be copied from the App Connector Capability Index and are addressed as domain.operation, e.g. im.send_message or docs.create_markdown. All business fields (chat_id, text, query, etc.) MUST be placed inside `payload`, never at the top level. Example: {\"platform\":\"feishu\",\"action\":\"im.send_message\",\"payload\":{\"chat_id\":\"oc_xxx\",\"text\":\"hello\"}}. Do not invent action names, do not use management actions such as list/guide/connect/status here.\n- **platform_connect**(action, platform, credentials, options, checkpoint) [capability_expand category: gateway]: List, guide, connect, disconnect, remove, or check status for external platforms using the App Connector management namespace. Supports REST and CLI backends. Use this for management actions such as list/guide/preflight/connect/status; use platform_action only for exact registered business actions.\n- **gateway_send**(platform, chat_id, text, thread_id) [capability_expand category: gateway]: Send a message to a connected external platform (Feishu group, Telegram chat, DingTalk conversation, etc.). Requires the platform to be connected via gateway_connect first. Use gateway_connect with action='list' to see connected platforms and available chat IDs.\n- **gateway_connect**(action, platform, credentials, options) [capability_expand category: gateway]: Connect, configure, or manage external platform integrations (Feishu, DingTalk, Telegram, Slack, Discord, etc.). Conversational flow: 1) call 'guide' to get setup steps + required fields, 2) present the steps to the user and ask for ALL required credentials in a single message, 3) call 'connect' with the credentials. Goal: complete in 1–2 user turns. NEVER include credential values in your text response.\n- **plugin_list**(): List the live plugin registry and cross-subsystem capability evidence. Use this before answering questions about whether LeapFlow supports plugins, self-evolution, plugin installation, hot reload, versioning, or other runtime capabilities.\n- **plugin_status**(plugin_id): Get detailed status of a specific plugin: its declared category, runtime dependencies, contributed tools, and fiber lifecycle state.\n- **plugin_versions**(plugin_id): List recorded source versions and active pointer for a profile-scoped plugin.\n- **plugin_propose**(requested_capability, plugin_id, proposed_tools, test_cases, risk_level, evidence): Create a side-effect-free PluginProposal from explicit capability-gap evidence. Use this before plugin_generate when a missing capability should be reviewed. Does not call an LLM, write files, or install anything.\n- **assess_compatibility**(manifest, source_path) [capability_expand category: plugin_management]: Assess whether a foreign plugin manifest or real DSH source bundle is compatible with LeapFlow. A source bundle assessment is static: runtime_ready stays false until restricted Node discovery during plugin_install. Returns component-level verdicts and limitations.\n- **plugin_generate**(plugin_id, description, proposal_id) [capability_expand category: system]: Generate a new ToolPlugin from a natural-language capability description. The LLM produces code that conforms to the ToolPlugin Protocol; it is then rigorously validated (syntax, structure, import, protocol conformance). The isolated sandbox smoke test runs later, at install-time. Returns the validated code but DOES NOT install it — installation is a separate approval-gated step via plugin_install.\n- **plugin_install**(plugin_id, code, marketplace_name, source_path, proposal_id, version_label) [capability_expand category: system]: Install a plugin from exactly one source: validated Python code, the configured Python marketplace, or a real DSH source bundle. DSH bundles run restricted Node discovery before registration; only public host tools are installed and client UI limitations are reported. Writes profile-scoped state and mutates the process-global registry. REQUIRES APPROVAL.\n- **plugin_rollback**(plugin_id, version) [capability_expand category: system]: Rollback a profile-scoped plugin to a recorded source version and reload it. REQUIRES APPROVAL.\n- **plugin_reload**(plugin_id, version_label) [capability_expand category: system]: Hot-reload a plugin at runtime. Disposes the old plugin fiber, re-imports its module, and registers a fresh instance. Existing in-flight turns are unaffected (snapshot isolation). REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_disable**(plugin_id) [capability_expand category: system]: Disable a plugin by disposing its fiber, removing its tools from the runtime registry. Cannot disable self_management itself. REQUIRES APPROVAL — this is a self-modification action.\n- **plugin_remove**(plugin_id, delete_source) [capability_expand category: system]: Terminally remove a plugin: dispose its fiber, unregister its tools, remove reload metadata, and optionally delete its profile-scoped source file. Cannot remove self_management itself. REQUIRES APPROVAL.\n- **plugin_enable**(plugin_id) [capability_expand category: system]: Re-enable a previously disabled plugin by reloading its module and registering a fresh instance. REQUIRES APPROVAL.\n- **hw_list**(): List connected hardware devices with their channel counts and measured quantities. Start here; it does not include operating limits.\n- **hw_describe**(device_id): Return the full reference for one device: every channel, its unit, its operating envelope, rate limit, reversibility, and required interlocks, plus any prior outcomes recorded for its writable channels. Required before commanding a device.\n- **hw_read**(device_id, channel_id): Read the current value of one device channel. Has no physical effect.\n- **hw_status**(device_id): Report connection health, halt capability, and recent notable events (threshold excursions, lost samples, stalled channels) for one device.\n- **hw_configure**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Set a configuration value or setpoint on a channel declaring effect=configure. Setpoints often have inertia: the value may need time to stabilise.\n- **hw_actuate**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Command motion or output on a channel declaring effect=actuate. This moves physical hardware; a repeat from an unknown state is not a safe retry.\n- **hw_dispense**(device_id, channel_id, value, conditions, dry_run) [capability_expand category: hardware]: Consume an irreversible resource on a channel declaring effect=dispense. Running this twice dispenses twice; never repeat it after a failure without first verifying what already happened.\n- **hw_estop**(device_id) [capability_expand category: hardware]: Stop all motion and output on a device immediately. Never requires approval; use it whenever device behaviour is unexpected.\n- **session_search**(query, limit) [capability_expand category: unclassified]: Search past conversation sessions in the current workspace for relevant context.\n- **session_list**(limit): List recent conversation sessions in the current workspace with stable ids, titles, dates, and summaries. Use for browsing past tasks or when user asks to see history without specific search terms. No keywords needed — returns chronological list.\n- **session_detail**(session_id, limit, offset, include_inactive) [capability_expand category: unclassified]: Read a paginated persisted transcript for one past conversation session in the current workspace. Use after session_list or session_search returns a session_id.\n- **click**(element_index) [capability_expand category: desktop]: Click a UI element by its element_index (from the latest observe_ui snapshot)\n- **get_clipboard**() [capability_expand category: desktop]: Read current clipboard text content\n- **list_apps**(filter, running_only) [capability_expand category: desktop]: List available applications on this system. Use to discover correct bundle_id before switch_app.\n- **list_windows**() [capability_expand category: desktop]: List all top-level windows with pid, window_id, title, and per-window state (minimized, on-screen). Call this first to pick the pid and window_id that observe_ui and other window tools require.\n- **observe_ui**(pid, window_id, query) [capability_expand category: desktop]: Snapshot one window's actionable UI elements, each tagged with an element_index for click/right_click/read_text. Re-observe after actions — indices belong to one snapshot. Requires the window's pid and window_id from list_windows.\n- **open_url**(url, app_id) [capability_expand category: desktop]: Open a URL in the default or specified browser\n- **read_text**(element_index) [capability_expand category: desktop]: Read the text content of a specific UI element from the latest snapshot\n- **right_click**(element_index) [capability_expand category: desktop]: Right-click a UI element to open its context menu. Returns visible menu items.\n- **screenshot**(pid, window_id) [capability_expand category: desktop]: Capture a screenshot for visual verification. With pid + window_id captures that window (works across all displays); defaults to the last observed window, or the full desktop when no window has been observed.\n- **scroll**(element_index, direction, amount, pid, window_id) [capability_expand category: desktop]: Scroll a scrollable area of a window. Omit element_index to scroll the window's focused/page scroller; pass one to scroll an exact element from the latest snapshot.\n- **select_text**(element_index) [capability_expand category: desktop]: Select all text in a UI element (focus + select-all, for subsequent copy)\n- **set_clipboard**(text) [capability_expand category: desktop]: Write text to the clipboard\n- **shortcut**(keys) [capability_expand category: desktop]: Execute a keyboard shortcut\n- **switch_app**(app_id) [capability_expand category: desktop]: Switch to an app (launch if needed, activate, verify)\n- **type_text**(text) [capability_expand category: desktop]: Type text into the currently focused element\n- **wait**(seconds) [capability_expand category: desktop]: Wait for a specified duration before continuing\n- **wait_until**(condition, pid, window_id, timeout, poll_interval) [capability_expand category: desktop]: Wait until a UI condition is met (polls UI tree). Returns elements when found or on timeout.\n- **wait_until_stable**(timeout, poll_interval, pid, window_id) [capability_expand category: desktop]: Wait until the UI stops changing (element set stabilizes across polls).\n\n## App Connector Capability Index\nLeapFlow can onboard and manage external apps through `platform_connect` and execute exact registered business actions through `platform_action`.\nFor requests about connecting, setting up, configuring, enabling, or managing a supported app, use `platform_connect` first instead of generating SDK/Webhook sample code.\n`platform_connect.action` is the management namespace: list, guide, preflight, connect, disconnect, remove, status, events_start, events_stop, events_status.\n`platform_action.action` is only for exact registered platform business actions listed below, such as `im.send_message`; never use management actions like `list` or `guide` there.\nAll business fields MUST go inside `payload`; top-level keys are only `platform`, `action`, and `payload`.\nDo not invent platform IDs or platform action names. If the needed action is not listed, ask for discovery/clarification instead of guessing.\nUse `platform_connect` with `action='guide'` and the matching `platform` to start onboarding; use `action='list'` when the app is unclear.\nWhen a pending onboarding state is present, continue from that state with `platform_connect` instead of asking the user to restate the app.\nSupported apps:\n- `api_server`: API Server (OpenAI Compatible) (category=api; backend=adapter; platform_action actions=none registered)\n- `dingtalk`: 钉钉 (DingTalk) (category=im; backend=adapter; platform_action actions=none registered)\n- `feishu`: 飞书 (Feishu/Lark) (category=im; backend=cli)\n - `calendar.create_event` payload={summary*, start_time*, end_time*, attendees} [write/high]\n - `docs.create_markdown` payload={title*, markdown*, folder_token} [write/medium]\n - `drive.search` payload={query*, limit} [read/medium]\n - `im.add_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.download_resource` payload={message_id*, file_key*, type*} [read/low]\n - `im.get_messages` payload={message_ids*} [read/low]\n - `im.list_chats` payload={page_size} [read/low]\n - `im.list_messages` payload={chat_id*} [read/low]\n - `im.list_thread_messages` payload={thread*} [read/low]\n - `im.remove_reaction` payload={message_id*, emoji_type*} [write/low]\n - `im.reply_message` payload={message_id*, text*} [send/high]\n - `im.search_chats` payload={query*, page_size} [read/low]\n - `im.search_messages` payload={query*} [read/medium]\n - `im.send_message` payload={chat_id*, text*, thread_id} [send/high]\n - `im.update_card` payload={token*, card*} [write/medium]\n - `im.update_message` payload={message_id*, text*} [write/medium]\n - `mail.search_unread` payload={query, limit} [read/high]\n - `sheets.append_row` payload={spreadsheet_token*, sheet_id*, values*} [write/medium]\n - `task.create` payload={title*, description, due_time} [write/medium]\n- `telegram`: Telegram (category=social; backend=adapter; platform_action actions=none registered)\n- `webhook`: Webhook (Generic) (category=webhook; backend=adapter; platform_action actions=none registered)\n\n## Tool Usage\nTools are normally invoked through the native function-calling mechanism, not by writing JSON in your reply\ntext. Only if the provider signals that native function calling is unavailable for this turn, fall back to a\nsingle JSON code block: `{\"name\": \"tool_name\", \"arguments\": {\"key\": \"value\"}}` — use this fallback format\nonly, never both. Only call a tool whose exact name appears in the tool index above and is currently callable\n(or reachable via `capability_expand`). Never invent, rename, alias, or guess a tool name, platform ID, or\nplatform action from argument shape or wording — if the index does not list it, it does not exist.\n`platform_connect.action` (list/guide/preflight/connect/disconnect/remove/status/events_start/events_stop/\nevents_status) is the App Connector management namespace; `platform_action.action` only accepts exact\nregistered business actions such as `im.send_message` shown in the App Connector Capability Index — never mix\nthe two namespaces. If a tool call returns an unknown/unavailable result, use the returned suggestions or\navailable names for a single retry instead of trying further variations of the same guess.\n\n**Side-effect action rule** (`platform_action` with effect=send/write/execute):\n- Call each unique action+payload **exactly once**. Never include duplicates in the same turn.\n- Once the result returns `\"completed\": true`, that action is DONE for this task. Do NOT call it again\n in any subsequent turn — immediately summarize the result for the user instead.\n- The system enforces idempotency: duplicate calls are blocked and will not execute.\n- If the user explicitly requests sending/writing multiple times, use distinct payloads per call.\n\n**Resource identifier provenance rule**:\n- NEVER fabricate, guess, or infer resource identifiers (chat_id, message_id, file_key, user_id, etc.).\n Every resource ID used in a side-effect action MUST come from a successful API response in this session.\n- If a read/list action fails (e.g. authorization error), you do NOT have valid resource IDs.\n Report the failure to the user — do NOT attempt the dependent write/send action with a guessed ID.\n- When a tool result contains `\"llm_instruction\"`, follow it exactly.\n\n## Guidelines\n1. **Direct answers first**: If you already know the answer, respond directly without tools.\n2. **Avoid redundant tool calls**: Do not call the same tool with the same arguments more than once in the same user turn. When an existing tool result already answers the user's request, stop calling tools and answer directly.\n3. **Use tools proactively**: When the user asks about files, time, system state, or needs actions performed, use the appropriate tool.\n4. **Chain tools when needed**: You can call multiple tools in sequence (e.g., list files → read file → summarize).\n5. **Handle failures gracefully**: If a tool fails, explain what went wrong and suggest alternatives. If it failed because of an unknown tool/platform/action name, retry once with an exact name from the returned suggestions, then explain rather than keep guessing.\n6. **Summarize results naturally**: After tool execution, synthesize the results into a helpful answer rather than dumping raw output.\n7. **Stay conversational**: Maintain a natural, helpful tone. Acknowledge context from earlier in the conversation.\n8. **Recall past work**:\n - Broad queries (\"之前做了什么\", \"列出任务\"): answer from the \"Recent Task History\" section already in your context. If insufficient, call session_list.\n - Specific lookups (\"上次那个配置怎么改的\"): call session_search with relevant phrases (NOT single characters).\n - Do NOT call search tools repeatedly with keyword fragments. One well-phrased call is better than ten fragmented ones.\n\n## Coding & Verification\nWhen working with code, prefer the precise built-in tools over ad-hoc shell: use `repo_map` to orient in an\nunfamiliar project, `code_search`/`file_find` to locate and `code_intel` for symbols, `edit_file` (anchored\nsearch-replace, or a unified `diff`) to change files — never rewrite a whole file to change a few lines — and\n`git_query` to inspect diffs/log. After edits, check `syntax_ok` in the result and run `test_run`/`lint_check`\nbefore declaring the work done. Batch independent read-only calls (search/read/query) into a single turn — they\nrun in parallel.\n\n## Presentation Style\n1. **Polished Markdown only**: Format user-facing answers with clean Markdown headings, short paragraphs, and concise bullets. Use tables only when they improve comparison or scanning.\n2. **Terminal-friendly layout**: Keep lines readable in a TUI; avoid dense walls of text, deeply nested lists, oversized ASCII art, or heavy visual blocks.\n3. **Elegant emphasis**: Use bold text sparingly for key terms and conclusions. Avoid excessive emojis, decorative symbols, repeated separators, or visual noise.\n4. **Theme-safe colors**: Do not emit ANSI escape codes, HTML color tags, Rich markup, or hardcoded color names. Rely on the TUI theme to render Markdown professionally.\n5. **No leaked tool protocol**: Never show tool-call JSON, internal schemas, raw observations, tool result payloads, or hidden reasoning in the final answer unless the user explicitly asks for raw/debug output. Treat any prior `{\"name\": ..., \"arguments\": ...}` blocks and `Tool result (...)` messages as internal execution context only.\n6. **Professional closure**: End with a concise conclusion or next step when helpful; avoid rambling after the useful answer is complete.\n\nWhen finished with all tool calls, respond normally without a JSON block, tool-call transcript, or process log.\n\n\n## Recent Session Summary\n- [user] List the connected hardware devices, then describe bench_r8 in full.\n\n## Task Contract\n- Task ID: turn-1\n- Original user request: List the connected hardware devices, then describe bench_r8 in full.\n- Workspace root: \n- Allowed roots: \n- Treat relative project paths as relative to the workspace root; never infer `.` as the project root when a workspace root is provided.\n- Workspace boundary is enforced by tools: do not read, search, edit, or run commands against paths outside the allowed roots unless the user explicitly requests an external path and the tool/approval policy permits it.\n- LeapFlow workspace config is optional at `/.leapflow/config.yaml`; runtime config is loaded from `~/.leapflow/config/user.yaml` and `~/.leapflow/profiles//config/*.yaml`.\n- Preserve this task contract across summarization, compression, tool loops, and memory retrieval.\n" + }, + { + "role": "user", + "content": "List the connected hardware devices, then describe bench_r8 in full.\nList the connected hardware devices, then describe bench_r8 in full." + }, + { + "role": "assistant", + "content": "", + "tool_calls": [ + "hw_list" + ] + }, + { + "role": "tool", + "content": "{\"ok\": true, \"devices\": [{\"device_id\": \"bench_r8\", \"display_name\": \"R8 Simulated Bench\", \"location\": \"journey-lab\", \"channels\": 3, \"writable\": 2, \"streaming\": 1, \"quantities\": [\"state.homed\", \"temperature\"], \"verified\": true, \"halt_supported\": true}], \"count\": 1, \"hint\": \"Call hw_describe(device_id) for channel limits before commanding a device.\", \"execution_id\": \"\", \"idempotency_key\": \"\", \"execution_policy\": \"read_only\", \"tool_call_id\": \"call_1\", \"execution_status\": \"completed\"}", + "tool_result": true + }, + { + "role": "assistant", + "content": "Operation interrupted.

The claim this document makes + +**Adding a peripheral requires no board code.** A new device appears on LeapBoard with +live values, a trace, a preview and controls because every panel is derived from the +*declaration* — not from a per-device view, an icon table, or a type switch. + +That is a contract, and it is testable. The board asks two questions of each channel, +both answered by declared fields: + +| Declared | Board renders | +|---|---| +| `representation: scalar` + `sample_rate_hz > 0` | value, trend, sparkline, envelope band | +| `representation: state` | value as-is | +| `representation: frame` | **preview panel** (`MediaPreview`) | +| `direction: readwrite` / `write` | **control** whose widget comes from the envelope | +| `privacy: environment` / `personal` | consent notice, and the read is gated | + +Nothing consults `device_class`. It is a free-form grouping label used for section +headings and nothing else, deliberately not an enum: the moment a device *type* decides +what is permitted, every new peripheral needs a core edit and an unrecognised one gets a +wrong default. + +--- + +## 2. Adding a peripheral: five steps + +### 2.1 Implement a `HardwareContextProvider` + +```python +class MyScannerProvider: + kind = "my_scanner" + + def discover(self) -> tuple[HardwareContext, ...]: + ... +``` + +`discover()` **must not connect to a device**. Discovery has to work with the hardware +powered off, and it runs during daemon boot — so it must also not block. Two rules follow +that are easy to get wrong: + +- **No device I/O, and no slow subprocess.** Reading a mount table, a sysfs node or an + in-process counter is fine. Opening a camera is not: on macOS that raises a system + permission dialog, and a background process cannot explain why one appeared. +- **Enumerate metadata only.** `leapflow.hardware.media` lists AVFoundation inputs by + parsing ffmpeg's own `-list_devices` output precisely because it never opens one. + +### 2.2 Implement a `HardwareTransport` + +Six methods: `open`, `close`, `read`, `write`, `probe`, `halt`. See +`src/leapflow/hardware/transport.py`. + +If the device produces images, additionally satisfy `FrameTransport`: + +```python +async def read_frame( + self, channel_id: str, *, max_width: int = 0, quality: int = 0 +) -> FrameReading: ... +``` + +This is a **side protocol, not a seventh core method**. Capability is discovered with +`isinstance(transport, FrameTransport)`, so most drivers never grow a method they cannot +implement. A device declaring a `frame` channel whose transport does not satisfy it is +refused on first preview with `failure_code="transport_not_frame_capable"` — a named +degradation rather than an `AttributeError`. + +`FrameReading` is deliberately **not** a `Reading`. Readings are appended to raw NDJSON +segments and downsampled into DuckDB windows; a frame has no mean and no bound, and a few +hundred kilobytes per sample would turn the segment writer into a disk filler with a +schedule. + +### 2.3 Register both + +Three ways, in ascending order of independence: + +```python +# In-tree: one row in the factory table. +_PROVIDERS["my_scanner"] = "my_pkg.provider:build_provider" + +# From a plugin, scoped so a hot reload cannot leave a stale factory behind. +scope.effect(register_provider("my_scanner", "my_pkg.provider:build_provider")) +scope.effect(register_transport("my_rig", "my_pkg.driver:build_transport")) + +# Out-of-tree: `pip install` is enough. +[project.entry-points."leapflow.hardware.providers"] +my_scanner = "my_pkg.provider:build_provider" +[project.entry-points."leapflow.hardware.transports"] +my_rig = "my_pkg.driver:build_transport" +``` + +Built-in names win over entry points: an installed package must not be able to hijack +`yaml`, `host` or `media` and change where a profile's device knowledge comes from. + +### 2.4 Declare the channels + +```yaml +channels: + - channel_id: frame + direction: read + quantity: image_frame + representation: frame # -> preview panel + media_type: image/jpeg + privacy: environment # -> consent gate + sample_rate_hz: 2.0 # capture *ceiling*, not a sampling cadence + - channel_id: exposure_us + direction: readwrite + effect: configure # -> hw_configure owns it + unit: us + envelope: + declared: true # -> slider, min..max, step from quantization + min_value: 100.0 + max_value: 33000.0 + quantization: 100.0 + reversible: true +``` + +Two field semantics are load-bearing and non-obvious: + +- **`sample_rate_hz` on a media channel is a capture ceiling.** `Channel.is_streaming` + is false for media, so no sampling loop is built and nothing is written to the reading + store. The preview path reads it as the fastest it may ask the device for frames. +- **The envelope *is* the widget specification.** `allowed_values` → select; + `min_value` + `max_value` → slider stepped by `quantization`; neither → plain field. + +### 2.5 Nothing else + +`leap hw scan` (or the daemon's rediscovery interval) admits it, and it appears on the +fleet board grouped by `device_class`, with a device page carrying whatever its channels +declared. + +--- + +## 3. Privacy: why a read can need consent + +`HardwareEffect` classifies what a **write** changes. It cannot express the difference +between a thermometer and a webcam: both are `effect: read`, with no envelope and nothing +to actuate, and one of them discloses the room. + +`PrivacyTier` is the declared fact that can: + +| Tier | Meaning | Read is | +|---|---|---| +| `none` (default) | discloses nothing about the surroundings | free | +| `environment` | observes the space around the machine (camera, microphone) | gated, MEDIUM | +| `personal` | observes the person using it (screen, location) | gated, HIGH | + +Consequences, all enforced in code: + +- **`allow_permanent=False`.** A standing, unexpirable grant to observe somebody's room + is not consent — it is the absence of it. A session-scoped grant still spares them a + prompt per frame. +- **Refusal precedes the transport.** `HardwareTools._consent_for_read` returns before + `registry.transport()` is called, because opening the device is what raises the + platform dialog. A refused read must never get that far. +- **Fail closed, three ways.** No gate installed (the in-process CLI binds none), a gate + that raises, and a gate that denies all produce `failure_code="consent_required"` with + a message naming the next step. + +### 3.1 Where consent is actually given + +A browser cannot grant itself a camera *by asserting so* — but it can carry the question +and the answer. Both surfaces work, and they differ only in where the prompt appears: + +| Surface | Prompt appears | Use when | +|---|---|---| +| **The board page** | inline, inside the preview panel that made the request | you clicked *Start preview* and are looking at it | +| **`/board preview `** | in the TUI | you want the grant before opening a browser | + +Both reach the same gate. What makes the page a legitimate surface is structural, not a +relaxation: + +- The prompt is **raised by the daemon's approval chain**, not invented in JavaScript. It + arrives carrying the risk assessment and *the choices the policy allowed* — the page + renders those verbatim, so it cannot offer an "always allow" the policy withheld. +- The answer goes back through **`approval.resolve`**, so the grant, the audit record and + the decision semantics stay the orchestrator's. +- The prompt only exists because **this page made the request**. The person answering is + the person who clicked. + +The mechanism is `_APPROVAL_ROUTED_METHODS` in `daemon/server.py`. +`ApprovalCoordinator.request_approval` returns `deny` when no approval route is installed, +and the daemon installs one for `command.execute` and for the two device observations +(`hardware.frame`, `hardware.read`). A routed request delivers its prompt as an interleaved +`stream.chunk` notification on its own socket, which +`DaemonClient.request(on_stream_event=...)` forwards — the dashboard forwards it to the +browser hub, and the request **waits** for the answer. + +That waiting is the point: answering completes the very request that raised the prompt, so +there is no second round trip and no window where a grant exists but the picture does not. +An unanswered prompt cannot leak, because a routed request registers, denies-on-exit and +unregisters exactly as a slash command does. + +A local environment camera uses a **session consent family**, not a per-device prompt: +one consent covers its probe, the following MJPEG stream, and another local camera looking +at the same physical space. Camera and microphone remain separate families; personal, +remote and unknown device classes remain per-device. The action summary, risk assessment +and audit record still name the actual device/channel, so only reusable grant identity is +grouped. + +The page promotes **Allow for this session** as the primary choice. **Allow once** returns +exactly one still frame or one level sample; it deliberately does not open a continuous +stream, so it never turns a one-shot decision into ongoing observation. + +### 3.2 Screens + +Screen-capture devices are **not enumerated by default** (`hardware.media_screens`). A +platform that presents the display as just another video input would otherwise put +"stream this person's screen" on the board beside the webcam, one click away. + +--- + +## 4. Operating it from the TUI + +`/board` is the operator surface, and every verb below reads or requests — none of them +commands a device directly. + +| Command | Does | +|---|---| +| `/board hardware` | the fleet: every attached peripheral, grouped by class | +| `/board devices` | the same list as text in the TUI — no browser needed | +| `/board device ` | the **same** `hardware` lens, focused on one device | +| `/board preview [channel]` | establish consent (prompt appears here), then open the preview | +| `/board rescan` | re-run discovery after a hot-plug | + +There is one hardware lens, not two. `hardware` renders the fleet; naming a device renders +that device. They were separate templates and the split did not pay for itself — +`hardware` and `hardware_device` read as synonyms in the lens list, and the second was +never a different *way of looking*, only a different subject. + +`` accepts a **unique prefix**, matching how `/board stop` already resolves a watch +id: discovered ids are long (`camera_0_macbook_pro`) and an ambiguous prefix reports the +candidates rather than guessing. Deliberately no completion is offered for the id — it +would be captured when the TUI started and keep offering a device that has since been +unplugged. + +`/board rescan` is ungated because every provider in the default set enumerates +passively. A scanner that transmits or leaves the host would need its own gate, which is +exactly why those are not in the default set. + +--- + +## 5. Preview: shared, bounded, self-releasing + +Two shapes, one gate. A **frame** channel streams pictures; a privacy-gated **scalar** +channel is a live meter, which is how a microphone's input level is presented. Both are +continuous disclosures of the surroundings, both need consent, and both are useless as a +static table cell. `inventory._is_previewable` decides from the declared representation, so +a non-camera frame source and a non-microphone level source work without a new case. + +| Channel | Endpoint | Transport | +|---|---|---| +| `representation: frame` | `GET /api/media/stream` | MJPEG (`multipart/x-mixed-replace`) | +| privacy-gated scalar | `GET /api/media/level` | JSON, polled four times a second into a browser-local waveform | + +MJPEG because an `` renders it natively — no player, no codec, no decode path in +JavaScript. The level channel is polled instead: the value is a number, so there is no +response to hold open. The board draws its last 96 readings as a **browser-local waveform**; +values are never persisted as audio history. + +The client asks for one frame (or one reading) first. That probe is what surfaces a +refusal as text — an `` cannot report *why* it failed, because `onerror` carries no +body. If the person chooses **Allow once**, that probe is the complete result; choosing +**Allow for this session** starts the continuous stream without asking a second time. + +`PreviewBroker` (`src/leapflow/hardware/preview.py`) owns the one path where a device +stays claimed across requests. Three properties, each present because its absence is a +real failure: + +1. **Shared upstream.** Most devices admit a single reader, so two viewers of one camera + must not open it twice. Frames are captured once per channel and handed to whoever + asks. +2. **Profile-bounded work.** The page offers Economy (640px / 4fps / JPEG 60), Balanced + (960px / 8fps / JPEG 75, default) and Detail (1280px / 12fps / JPEG 85). The daemon + clamps every request against the channel declaration and `hardware.preview_*` ceilings; + a hand-edited URL cannot raise capture cost. Profile identity is part of the cached + frame key, so selecting Detail never shows a cached Economy frame. +3. **Self-releasing.** A browser tab closing is not an event the daemon can observe, so + the lease expires on **silence**: no frame requested within + `hardware.preview_idle_timeout_s` drops the transport, which is what actually powers + the camera down. + +The Preview selector is **not** a durable config editor. It records a browser-local +preference per device/channel and sends a bounded request for the next live preview; the +daemon is authoritative for every compute limit. The default balanced profile is chosen +to make a camera useful without spending Detail's CPU/bandwidth in every open board. + +The wire path is `MediaPreview` → `GET /api/media/stream` (MJPEG) → `hardware.frame` RPC +→ broker → `read_frame`. + +--- + +## 6.

There is deliberately no second write +path: the handler owns every feasibility check, the approval descriptor, the audit record +and the side-effect verdict, and a parallel implementation would be a second gate free to +disagree with the one that actually protects the device. + +The tool is chosen from the channel's **declared effect class**, never from the caller. +Letting the board name it would allow routing a motion command on an `actuate` channel +through `hw_configure` and getting the gentler classification. + +The board may carry an approval prompt raised by its own preview request and resolve it +through `approval.resolve`; the daemon still owns risk classification, policy, grants and +audit. The board cannot invent choices or approve an unrelated action. Device controls use +the same `hardware.write_request` path described above. + +--- + +## 7.
