FastAPI Patterns

What it does

When installed, the agent follows a set of FastAPI conventions when you ask it to build or review a Python web API. It suggests a layout that separates routes, Pydantic request/response schemas, dependency injection, and database logic, and it provides copy-ready code examples for async endpoints, authentication dependencies, error handling, and OpenAPI docs. It also points out common production risks, such as leaking password hashes in responses or combining wildcard CORS origins with credentials.

Try asking

• “Review my FastAPI app's main.py and routers for production issues”Copy
• “Set up a FastAPI project layout with dependencies, schemas, and tests”Copy
• “Write an async FastAPI endpoint that paginates users from a SQLAlchemy database”Copy
• “Add JWT-based authentication dependency to my FastAPI routes”Copy

Get better results

• Name the specific file or route you want reviewed so the agent applies the relevant section.
• Ask for the pattern adapted to your own models and database, rather than pasting the examples unchanged.
• Check generated auth and CORS code against your framework version and security requirements before deploying.
