Add the tinytools repository as a vendor submodule tracking its main branch for shared tooling. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Update the tinytools submodule to a newer revision to incorporate its latest changes. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add the path dependency so the crate can share the tool trait with hosts while keeping execution context types in the harness. This remains path-only until tinytools is published. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Re-export tool name and context detail rendering from `tinytools` instead of maintaining duplicate implementations in the harness. This keeps rendering behavior consistent across hosts and avoids divergent prefix handling. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Implement the tinytools context trait for the harness execution context, allowing tools to access workspace, policy, thread, and output limit information without depending on harness internals. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Vendors tinytools at vendor/tinytools and depends on it, so the harness and a host application name the same tool types rather than structural twins with hand-written conversions between them. Two changes fall out: humanize_tool_name / context_detail_from_args and ContextDetailOptions move down into tinytools and are re-exported here. Naming a tool for a human is not harness work, and the duplicated prefix list was already carrying a comment warning that two copies is how one silently stops stripping a prefix the other does. ToolExecutionContext gains a tinytools::ToolRunContext impl. tinytools cannot name this type -- this crate depends on it, so an edge back would be a cycle -- and a tool still needs its isolated workspace root. The trait exposes only what a tool reads: the workspace root and policy id, the thread id, and the turn output budget. The run id, event sink, cancellation token and streaming flag stay internal, because a tool that wanted them would be reaching into the run rather than doing its job. Co-authored-by: Medulla <medulla@tinyhumans.ai>
Move workspace descriptors and sandbox modes into tinytools so they share the tool vocabulary and types. Keep harness-specific violation reporting in a free enforcement function while preserving fail-closed path validation. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
ToolExecutionContext now returns the complete workspace descriptor through the updated tinytools context interface, preserving access to workspace root and policy data. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Update workspace enforcement coverage to call the shared helper while preserving assertions for allowed and blocked paths. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Both are tool vocabulary -- the descriptor's own docs describe it as telling a tool which filesystem root it may touch -- so they move down beside the ToolRunContext trait that reads them, and are re-exported here at their historical paths. No caller outside this crate changes. WorkspaceIsolation stays: preparing and tearing down a worktree is harness work and returns this crate's Result. So does the fail-closed path gate, which needs an EventSink and this crate's error type; it becomes the free function enforce_workspace_path, because an inherent method on a now-foreign type is not allowed. Its only two callers were this crate's own tests. Co-authored-by: Medulla <medulla@tinyhumans.ai>

📝 WalkthroughWalkthroughThe harness now uses shared tool and workspace vocabulary from the vendored Changestinytools integration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The refactor makes the release workflow unsafe because repository-controlled build commands can access a write-capable token, and releases will fail because the new path-only tinytools dependency cannot be packaged for publication yet. Merge should be blocked until the workflow credentials and publication path are corrected; a documentation example also needs a missing import. Poem

actions/checkout v7 persist-credentials default README credentials local git config
💡 Result:
In actions/checkout v7, the persist-credentials input defaults to true [1][2]. When enabled, this setting configures the authentication token (or SSH key) in the local git configuration of the checked-out repository [1][3]. This allows your workflow scripts to perform authenticated Git commands, such as pushing changes or fetching submodules, without additional manual setup [1][2]. Key points regarding this behavior include: * Mechanism: The action modifies the local git configuration to include the necessary credentials [1][3]. To enhance security in recent versions, credentials are persisted to a separate file (e.g., using includeIf) to avoid exposing them directly in standard configuration locations [4][5]. * Cleanup: The action performs a post-job cleanup step to remove these credentials, ensuring they do not persist after the workflow job completes [1][2]. * Security Considerations: If you do not require authenticated git operations within your workflow, you can opt out of this behavior by setting persist-credentials to false [1][2]. * Documentation: The official README for actions/checkout v7 confirms that persist-credentials is true by default and that it is used to configure tokens or SSH keys in the local git config [1][2].

Disable checkout credentials before running repository code. actions/checkout@v7 persists the GitHub token by default. This job grants contents: write and runs Cargo commands before pushing. A compromised build script can access the token. Set persist-credentials: false, then provide a least-privilege token only to the push step, as in .github/workflows/ci.yml.

Real finding, but declining it in this PR — flagging rather than silently ignoring, and I would support it as its own change.
The concern is accurate: release.yml grants contents: write, actions/checkout@v7 persists the token by default, and Cargo commands run before the push — so a compromised build script could reach the token.
Two reasons it does not belong here:
- It is pre-existing. That checkout predates this PR; my only edit to the file was adding
submodules: recursive, which the new path dependency requires. The exposure is unchanged by this branch in either direction. - The suggested fix is not a one-liner, and getting it wrong breaks releases. This job actually pushes —
git push origin "HEAD:${GITHUB_REF_NAME}"andgit push origin "${RELEASE_TAG}"at lines 126-127. Settingpersist-credentials: falsewithout first wiring a least-privilege token into those two steps breaks every release, and it would break on aworkflow_dispatchthat nobody runs on a PR — so CI here would stay green while the next release failed. Your own label agrees it is a heavy lift.
Doing that blind, in a PR about tool-type vocabulary, trades a theoretical token exposure for a real chance of a broken release. It deserves its own PR where the token wiring can actually be exercised.
Leaving this thread open rather than resolving it, so it stays visible as accepted-but-deferred instead of disappearing.

@senamakel, understood. The finding is valid, but it is outside this PR’s scope and needs release-path validation.
I will keep the thread open. Would you like me to create a GitHub follow-up issue for the credential isolation change?

The sibling wiki entry declares no branch, so this repository's own convention is to omit it -- the line was copied from openhuman, which is a different repository with a different convention. It also has no effect here. A branch is read only by 'git submodule update --remote', and nothing in this repository runs that: CI uses actions/checkout with submodules: recursive, which checks out the gitlink commit. The pin is, and always was, the gitlink. Co-authored-by: Medulla <medulla@tinyhumans.ai>

tinytoolsatvendor/tinytoolsand takes the tool vocabulary from it instead of declaring a parallel copy.The point is type identity, not tidiness.
tinyagents' tool types and OpenHuman's were structural twins with a hand-written seam between them. Now a tool implemented againsttinytools::Tooland the trait this harness runs a loop over are the same trait — a host implements a tool once and both sides accept it, with nothing at the boundary to get subtly wrong.What moved down, and why each one
humanize_tool_name,context_detail_from_args,ContextDetailOptions— naming a tool for a human is not harness work. The duplicated prefix list was already carrying a comment in this repo warning that two copies is how one silently stops stripping a prefix the other does; that comment is now unnecessary rather than aspirational.WorkspaceDescriptor,SandboxMode— the descriptor's own doc comment describes it as telling a tool which filesystem root it may touch, which is tool vocabulary by its own account. Both are re-exported here at their historical paths, so no caller outside this crate changes.What deliberately stayed
WorkspaceIsolation— preparing and tearing down a worktree is harness work and returns this crate'sResult.WorkspaceDescriptor::allows()(lexical, pure) moved;enforce()needs anEventSinkand this crate's error type, so it stays. It becomes the free functionenforce_workspace_path, because an inherent method on a now-foreign type is not allowed. Its only two callers were this crate's own tests.ToolSchema/ToolCall/ this crate's ownToolResult/ToolPolicy/ToolTimeout. These are the model-facing dialect vocabulary and are a different concern from the host-facing tool surface. They are untouched. The name collisions between the twoToolResults and the twoToolTimeouts are a deliberate boundary, not drift.ToolExecutionContextnow implementstinytools::ToolRunContextThis is the load-bearing piece.
tinytoolscannot nameToolExecutionContext— this crate depends ontinytools, so an edge back would be a cycle — and a tool still needs its isolated workspace root.The trait exposes only what a tool reads: the workspace descriptor, the thread id, and the turn output budget. The run id, event sink, cancellation token and streaming flag stay internal, because a tool that wanted them would be reaching into the run rather than doing its job.
The width was measured, not guessed: across the 44 OpenHuman files touching this type, the only fields read were
.workspace(24 sites),.thread_id(1) and.max_turn_output_tokens(1).workspace()needs no conversion —WorkspaceDescriptoristinytools' type now, so the field is already the right one.Verification

This crate can no longer be published to crates.io while its
tinytoolsdependency is path-only. Nothing breaks today — OpenHuman patches this crate to a local checkout and has since #1061 — but publishingtinytoolsis now a prerequisite for publishingtinyagents, andtinytoolshas no release workflow yet. Recorded in that repository'sAGENTS.md.Clone with
