Pi extension lifecycle and registration patterns. When NOT to use: single registration event (use direct API calls); for child worker lifecycle (use child-pi-spawning).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# pi-extension-lifecycle Use this skill when working on Pi extension registration or lifecycle behavior. ## Source patterns distilled - Pi core: `source/pi/packages/coding-agent/src/core/extensions/types.ts`, `loader.ts`, `runner.ts` - Pi examples: `source/pi/packages/coding-agent/examples/extensions/` - pi-crew extension entry: `src/extension/register.ts`, `src/extension/registration/*.ts` ## Rules - Register tools, commands, shortcuts, widgets, providers, and event handlers from the extension factory or lifecycle callbacks. - Tool definitions should use a TypeBox schema and an `execute(toolCallId, params, signal, onUpdate, ctx)` handler. - Use fresh `ExtensionContext`/`ExtensionCommandContext` after session replacement (`newSession`, `fork`, `switchSession`, `reload`). Do not retain old context references for later work. - For session-scoped work, derive session identity from `ctx.sessionManager.getSessionId()` and pass it into pi-crew `TeamContext`. - Prefer small registration modules under `src/extension/registration/`; keep `index.ts` minimal. - Clean up intervals, event subscriptions, child processes, and watchers on session switch/shutdown. …

How to install
mdr add baphuongna/pi-crew/pi-extension-lifecycle@sha256:d56136641106f94aThe line at the top of this page pins the label git:20260911.c97bc57, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
