Builds and updates the API in `packages/api` using this repo's module layout, shared DTOs, response envelope, guards, services, entities, and e2e test conventions. Use for controllers, services, modules, auth flows, database changes, migrations, and integration tests.
Use when building React applications in .tsx files. Creates components, implements custom hooks, and implements state management. Invoke for Server Components, Suspense boundaries, useActionState forms, performance optimization, or React 19 features.
Safely create, apply, and revert TypeORM migrations in packages/api. Use for any database schema change, entity field change, or when a migration fails locally or in deploy.
Write Jest unit tests for API services following this repo's mock/factory/AppError conventions. Use when adding or extending tests in packages/api/src/tests.

Adding one resource touches ~11 files across three packages. Follow this order exactly.
