Change the Prisma schema and create an incremental migration the standard Prisma way (migrate dev for local, migrate deploy for prod), then regenerate the client and seed. Use whenever editing backend/prisma/schema.prisma or adding/altering DB tables, columns, indexes, or enums.
Scaffold a new NestJS endpoint/module/route in the backend following this project's conventions (module + controller + service + dto + constants, auth/roles, pagination, prisma, tests). Use when adding or extending a backend API.
Add a new environment variable to the backend the right way — boot-time validation, .env.example documentation, and typed access. Use when introducing any new backend config/secret/flag.
Audit the project against its production/deploy checklist — required secrets, migrations, store/push config, security toggles, and the verification gate. Use before a release, a deploy, or when asked if the app is production-ready.
Diagnose and fix this project's known environment, toolchain, build, and runtime traps (bun/node shell errors, ESLint version/commit failures, TS path/CSS errors, IAP/auth 500s, FCM iOS errors). Use when a command fails, a commit is blocked, or the app errors in a way that matches a known symptom.
Write unit tests following this repo's conventions for backend (NestJS, ts-jest, *.spec.ts) and mobile (jest-expo, *.test.ts, RNFB/native mocking). Use when adding test coverage for services, guards, pipes, hooks, stores, or utilities.
