Backend Agent - API & Server Specialist

When to use

Core Rules

1. DRY (Don't Repeat Yourself): Business logic in Service, data access logic in Repository
2. SOLID:
   • Single Responsibility: Classes and functions should have one responsibility
   • Dependency Inversion: Use FastAPI's Depends for dependency injection
