Add Feature End-to-End

Implement feature described in $ARGUMENTS across the full stack.

Step 0: Decide Scope

Before writing code, answer:

CE, EE, or both? If both → use hooksFactory (CE default + EE override in app.ts)
Need a plan flag? → Add to PlatformPlan entity + LicenseKeyEntity type + plan constants in shared
Need a Permission? → Add to Permission enum in shared
Affects billing/quotas? → Add enforcement in controller
Must work embedded? → Check EmbeddingState in frontend
Project-scoped or platform-scoped? → Filter queries accordingly

Step 1: Shared Types (`packages/core/shared`)

Define Zod schemas + z.infer types in src/lib/{domain}/
Export from src/index.ts barrel
Bump version in package.json (patch for fix, minor for new export)

Step 2: Server (`packages/server/api`)

Read .agents/features/<module-name>.md first (e.g. .agents/features/tables.md for the tables module).

Entity: Use EntitySchema + BaseColumnSchemaPart + ApIdSchema. See tables/table/table.entity.ts.
Register entity: Add to getEntities() in database-connection.ts (REQUIRED — TypeORM doesn't auto-discover)
Migration: Read playbook → create class → import in postgres-connection.ts → add to getMigrations() → handle PGlite
Service: Factory (log: FastifyBaseLogger) => ({...}) if logging needed, plain object otherwise. See tables/table/table.service.ts.
Controller: FastifyPluginAsyncZod. Route configs AFTER controller. securityAccess required. See tables/table/table.controller.ts.
Project ownership: Add entitiesMustBeOwnedByCurrentProject hook if returning project-scoped data
Module: Register in app.ts (CE or EE section)
EE-only: Put in src/app/ee/, gate with platformMustHaveFeatureEnabled((p) => p.plan.myFlag)
Side effects: Separate *-side-effects.ts file if mutations trigger events/webhooks

Step 3: Worker (if queued work needed)

Add to SystemJobName or WorkerJobType enum in shared
Add handler, register in app.ts via systemJobHandlers.registerJobHandler()

Step 4: Frontend (`packages/web`)

Feature folder: src/features/{feature}/api/, hooks/, components/
API client: See features/tables/api/tables-api.ts
Hooks: See features/tables/hooks/table-hooks.ts
Route: React.lazy() + ProjectRouterWrapper() + RoutePermissionGuard + SuspenseWrapper
Translations: packages/web/public/locales/en/translation.json only
Feature flags: flagsHooks.useFlag() or <FlagGuard>

Step 5: Tests

API test: packages/server/api/test/integration/ce/{feature}.test.ts
Use setupTestEnvironment() + createTestContext(app)

Step 6: Verify

npm run lint-dev
npm run test-api
