Codepit The toolbox

An async API specialist for FastAPI work

A subagent for building FastAPI services with SQLAlchemy 2.0 and Pydantic V2: async endpoints, WebSockets, auth, caching and microservices. It starts from the Pydantic models and writes async tests.

How it works

Contract

Design the API contract with Pydantic models first.

Build

Write async endpoints with error handling and validation.

Test and tune

Write async tests for edge cases, add caching and pooling, and document the API in OpenAPI.

When it kicks in

  • FastAPI development
  • Async optimization
  • API architecture

Claude reaches for it when the task is a FastAPI service, or you can ask for it by name.

Try saying

>Create a FastAPI microservice with async SQLAlchemy and Redis caching

Claude hands it to fastapi-pro, which defines the models, builds async endpoints on SQLAlchemy, adds Redis caching and writes async tests.

Comes with python-development

This agent ships in the python-development plugin, so you also get two more agents, 16 skills and a scaffolding command.
