# Python back ends: FastAPI, Docker and AI agents

Find the skill that fits the task in the table, read its file in full before you start, and follow it. If a skill needs a local tool and you are on claude.ai without one, follow that skill's "Without local tools" section.

| Skill | What it does | When to use | File |
|---|---|---|---|
| Modern Python | Configures Python projects with modern tooling (uv, ruff, ty). | Use when creating projects, writing standalone scripts, or migrating from pip/Poetry/mypy/black. | skills/modern-python.md |
| Production FastAPI | Production-grade FastAPI patterns — structured logging, health checks, graceful shutdown, middleware, Pydantic v2, async patterns, error handling… | Use this skill when the user is building or modifying a FastAPI application, working with Pydantic models, configuring Starlette middleware, setting up Uvicorn/Gunicorn, or asks about FastAPI best… | skills/production-fastapi.md |
| Production Docker | Docker production hardening — multi-stage builds, non-root users, distroless images, BuildKit secrets, layer optimization, security scanning, and compose best… | Use this skill when the user is creating or modifying Dockerfiles, docker-compose files, .dockerignore, or containerizing applications. | skills/production-docker.md |
| Building Pydantic AI agents | Build AI agents with Pydantic AI — tools, capabilities (including on-demand loading), structured output, streaming, testing, and multi-agent patterns. | Use when the user mentions Pydantic AI, imports pydantic_ai, or asks to build an AI agent, add tools/capabilities, defer capability loading, stream output, define agents from YAML, or test agent… | skills/building-pydantic-ai-agents.md |
