Python Mastery

What it does

Python Mastery is a hands-on skill that equips an agent to author, review, and improve Python code using modern standards (targeting Python 3.11+). It provides a structured checklist for project setup, type-hinted code, async patterns, Pydantic/dataclass usage, testing with pytest, and FastAPI patterns. The skill emphasizes reproducible project scaffolding (pyproject.toml / uv recommendations), type safety, and pragmatic error-handling.

When to use it

Trigger this skill when a user asks an agent to write or debug Python scripts, set up a Python project, review code for quality (type hints, resource cleanup, async correctness), or convert synchronous code to async. Also applies to help with packaging, CI configuration, and writing tests. Good for developer-facing assistants and CI bots.

What's included

• Scripts: none detected inside the skill folder, but the skill references recommended commands and project templates (uv, pyproject.toml examples).
• References: curated patterns and example snippets are included in the SKILL.md; the repository contains a references/ directory with extended guides.
• Instructions: clear step-by-step guidance for environment setup, typing discipline, dataclasses vs Pydantic, async best practices, testing patterns with pytest, FastAPI examples, and debugging common errors. Also a code-quality checklist and anti-patterns.

Compatible agents

Coding assistants (Claude Code, Copilot-style review bots, local LLM orchestrators) and developer tooling integrations that can run linters, tests, or generate code and PRs.
