What fastapi-development does

This skill guides AI agents in structuring Python web applications on top of FastAPI. It directs code generation toward proper async/await usage, route operations with Path or Query parameters, and modular router patterns. Validation relies on Pydantic schemas, enforcing data types, nested models, and custom validation methods.

It also covers background tasks, dependency injection, and database integration workflows. Running the resulting API endpoints requires an external ASGI server such as uvicorn[standard].

What it helps with

  • build REST APIs with Pydantic request and response schemas
  • implement asynchronous endpoints using async and await
  • validate path and query parameters with built-in FastAPI tools
  • structure nested models and custom data validators

Example prompts for the agent

  • Create a FastAPI search endpoint with validated query parameters
  • Build a Pydantic schema for user registration with email validation
  • Write an asynchronous CRUD router for items using dependency injection

What does fastapi-development do?

It provides architecture patterns for FastAPI, guiding the assistant to write type-safe endpoints, Pydantic data schemas, and clean async routes.

What packages are required to run the generated code?

You need fastapi along with an ASGI server like uvicorn[standard]. Database tasks or authentication will require additional libraries such as sqlalchemy or python-jose.
