API Design Pro

Intent

Ensure the backend API is robust, scalable, and well-documented. Applies FastAPI-specific patterns (Dependency Injection, Background Tasks, Pydantic Schemas).

Checklist

1. Pydantic Validation: Are all request/response models strictly typed?
2. Error Handling: Are meaningful HTTP exceptions (400, 404, 500) used correctly?
3. Dependency Injection: Use Depends() for database sessions, authentication, and service instances.
4. Performance: Check for N+1 query problems in SQLAlchemy/Tortoise and ensure async/await is used properly.
5. Security: Ensure OAuth2/JWT tokens are verified where necessary.
