This skill provides a comprehensive guide and code patterns for mastering FastAPI's dependency injection (DI) system. It transforms how an agent helps users build APIs by moving from simple function calls to professional, modular architectures.
Use this skill when developing FastAPI applications that require reusable services, database session management, complex authentication/authorization chains, or advanced caching strategies.
