python-pro · davila7 — Claude Code skill: modern Python 3.12+ work

A Claude skill that steers Python 3.12+ development: async patterns, typing, profiling, plus uv, ruff, pydantic and FastAPI.

What python-pro does

The skill hands the agent a Python 3.12+ expert role and a matching toolset: uv for packages, ruff for linting and formatting, mypy and pyright for type checks, pytest with plugins for tests. It works in steps — confirm runtime, dependencies and performance targets first, pick patterns next, then implement, test and profile for latency and memory.

Coverage runs from async/await with asyncio, aiohttp and trio through dataclasses, pydantic models, structural pattern matching, protocols and generics. Web work gets its own sections: FastAPI, Django, Flask, SQLAlchemy 2.0+ with async support. Data and ML, Docker and Kubernetes deployment, and advanced patterns like dependency injection and metaprogramming are in there too.

The skill states its own limits: not for non-Python stacks, not for basic syntax tutoring, and not useful when you cannot touch the runtime or dependencies. Worth checking before you install — if your environment is pinned, the 3.12+ advice stays theoretical.

What it helps with

  • move a project from pip to uv
  • speed up I/O-bound code with async
  • wire ruff and mypy into one pipeline
  • stand up a FastAPI service with pydantic validation
  • find a bottleneck with a profiler

Example prompts for the agent

  • Rewrite this module in Python 3.12 with type hints and async
  • Set up uv and ruff for this project and add pre-commit
  • Profile this code and tell me what to optimize

What does python-pro do?

It helps write and review Python 3.12+ code: async patterns, type hints, pytest suites, profiling, and modern tooling such as uv and ruff.

When should I skip python-pro?

It is not for non-Python stacks or basic syntax tutoring. It also will not help if you cannot change the runtime or dependencies.
