Python Patterns

This skill is for day-to-day Python code quality: readability, correctness, maintainability.

If you are doing asyncio-heavy work, prefer python-async-patterns. If the task is profiling, GIL/free-threading, or experimental JIT, use python-performance.

When to activate

• Writing/refactoring Python modules, libraries, services
• Reviewing PRs for idioms, clarity, and footguns
• Introducing typing or improving error handling
• Designing lightweight data models and APIs
• Choosing threads vs processes vs subinterpreters (not asyncio)
