+# pi-crew Development Notes
+
+This package is a Pi extension for team orchestration.
+
+## Rules
+
+- Keep `index.ts` minimal; register functionality from `src/extension/register.ts`.
+- Prefer small modules over large orchestrator files.
+- Do not copy source from SUL-licensed projects. `oh-my-openagent` is concept-only inspiration.
+- MIT sources such as `pi-subagents` and `oh-my-claudecode` may be adapted with attribution in `NOTICE.md`.
+- Avoid `any`; use `unknown` plus validation for tool/config inputs.
+- Avoid dynamic inline imports.
+- Do not hardcode global keybindings without user configurability.
+- Default execution uses child Pi workers. Keep it safe through runtime limits, depth guards, and explicit disable controls (`executeWorkers=false`, `runtime.mode=scaffold`, `PI_CREW_EXECUTE_WORKERS=0`, or `PI_TEAMS_EXECUTE_WORKERS=0`).
+- Worktree cleanup must preserve dirty worktrees unless `force` is explicitly set.
+- Management deletes must require `confirm: true`; referenced resources should be blocked unless `force: true`.
+- After code changes, run `npm test` from `pi-crew/` unless explicitly told not to.
+
+## Important commands
+
+```bash
+npm test
+```
+
+## Important paths
+
+- `src/extension/team-tool.ts` — main tool actions
+- `src/runtime/team-runner.ts` — workflow scheduler
+- `src/runtime/task-runner.ts` — task execution and artifacts
+- `src/state/` — durable state/event/artifact store
+- `src/worktree/` — worktree creation and cleanup
+- `agents/`, `teams/`, `workflows/` — builtin resources
