There is no static write-path declaration on packages or profiles (CL-6952 removed it — no shipped director ever set one). Instead, `agent-fleet.ts` tracks each running dispatch by cwd; a new mutating dispatch that lands on the same cwd as a live mutating peer (`pending_init`/`running`, and not a declared read-only `modelRole` of `explore`/`plan`/`review`/`test`) records at most one `concurrent-lane-overlap` entry per cwd wave in `intervention-log.ts` (class `conflict`). The wave flag clears when no live mutating writer remains for that cwd. Terminal-but-unsettled lanes (for example cancelled with `finishedAt` set while the run promise has not reached `finally`) are pruned from the map and do not warn. This is advisory only — it never blocks the spawn, since cwd overlap does not prove the two lanes touch the same files. -7.

The handler refuses names already attached at spawn or already loaded this session (short “already in context”; it does not dump the body again). Otherwise it calls `resolveSkillBody`, strips the frontmatter, and returns the body as the tool result. 2. **Operator** — `/` from `loadSkillCommands` sends the same SKILL.md body (plus typed args) to the primary as a user turn. Skills with `user-invocable: false` are omitted from the slash registry and remain `use_skill` only. Skywalker then follows the recipe. Which plugin skill directories are in scope is decided in `runner.ts` / `skillDirsFromEnabledPlugins`, which passes the enabled plugins' dirs to both `discoverSkills` (for the listing) and the `use_skill` tool (for resolution). Project-local `.agents`/`.claude`/`.codex/skills` are always searched. Slash-command registration is first-wins (built-ins, then plugins in discovery order), so a first-party `/implement` stays first-party if a marketplace plugin of the same slash name is also enabled. diff --git a/docs/IMPLEMENTATION.md b/docs/IMPLEMENTATION.md index d86233895..d12906cdf 100644 --- a/docs/IMPLEMENTATION.md +++ b/docs/IMPLEMENTATION.md @@ -168,7 +168,7 @@ Twenty packages under `src/agent/directors//` register in `DIRECTOR_REGISTRY **Codex tool proxies.** When the active provider is Codex (`isCodexProviderName`), `createAgentToolset` and `runSubAgent` mount `apply_patch`, `shell`, and `update_plan` stringTools from `createCodexToolProxies`, all forwarding through the same posix `ToolRunner` seam (`runTool`) so permission plugins still apply. `apply_patch` parses the Codex envelope and forwards each op (`write_file` / `delete_file` / `read_file`). `shell` — the native Codex name is `shell`, not `exec_command` — normalizes Codex's `command` (string or `["bash","-lc",script]`-style argv array), `workdir`, and `timeout_ms` onto `run_shell`'s `{command, cwd?, timeout?}` and is gated by `allowShellFromCapabilities` (mirrors `allowDeleteFromCapabilities` against `run_shell`). `update_plan` maps Codex's `plan: [{step, status}]` onto `manage_tasks(action: "create")`; `pending`/`in_progress`/`completed` map to `todo`/`doing`/`done` — `manage_tasks`'s `cancelled` status has no Codex equivalent and is never produced by this proxy. Primary strips `apply_patch` after mount (Corbits DIY stays on `write_file` / `edit_file` / `delete_file`); `shell` and `update_plan` stay on primary (same classification as `run_shell` / `manage_tasks`). Build and docs worker allowlists (`BUILD_TOOLS` / `DOCS_TOOLS`) include `apply_patch` so Codex workers keep the proxy after the capability filter. `CORE_TOOL_NAMES` does not list it. 6. There is no static write-path declaration on packages or profiles (CL-6952 removed it — no shipped director ever set one). Instead, `agent-fleet.ts` tracks each running dispatch by cwd; a new mutating dispatch that lands on the same cwd as a live mutating peer (`pending_init`/`running`, and not a declared read-only `modelRole` of `explore`/`plan`/`review`/`test`) records at most one `concurrent-lane-overlap` entry per cwd wave in `intervention-log.ts` (class `conflict`). The wave flag clears when no live mutating writer remains for that cwd. Terminal-but-unsettled lanes (for example cancelled with `finishedAt` set while the run promise has not reached `finally`) are pruned from the map and do not warn. This is advisory only — it never blocks the spawn, since cwd overlap does not prove the two lanes touch the same files. -7.
