What is the FastAPI Claude Code skill?

It is a specialized capability for Claude Code that provides domain-specific patterns, best practices, and implementation guidance for building web APIs using the FastAPI framework.

How does it handle database connections?

It uses FastAPI's dependency injection system to manage database sessions (like SQLAlchemy) efficiently, ensuring connections are properly opened and closed during the request lifecycle.

Does this skill support Pydantic validation?

Yes, the skill includes detailed patterns for using Pydantic models to ensure automatic request validation, field constraints, and response serialization.

Can it help organize large API projects?

Absolutely. It promotes a structured approach using APIRouters to split routes by resource, alongside a clear separation of schemas, services, and repositories.
