Ty

This teaches Claude how to use ty, Astral's new Python type checker that's positioning itself as a faster replacement for mypy and Pyright. The skill covers the basics well: when to use `uv run ty` versus `uvx ty`, common commands for checking files and directories, and configuration in pyproject.toml. It's opinionated in the right ways, like preferring rule-specific ignores over blanket suppressions. The migration mappings from mypy and Pyright are helpful if you're switching tools. Worth having if you're working in Python projects that have adopted ty, though honestly most projects are still on mypy or Pyright for now.
