| -------------------------- | --------------------------------------------------------------------------------- |

| Scripts                    | [package.json](../package.json) scripts (`lint`, `format`, `test`, `check`)       |
| Pi peers                   | `@earendil-works/pi-coding-agent` and matching `pi-*` peers in `peerDependencies` |

Default extension toggles: `defaultEnabled` in [`src/config/bundled-extensions.ts`](../src/config/bundled-extensions.ts). Adding a bundled row: [docs/design.md](design.md#adding-a-bundled-extension).
