Agent Skills: uv

Use `uv` instead of `pip` / `python` / `venv` for Python work in repos that have adopted uv. Use when running Python scripts (`uv run`), adding dependencies (`uv add`), creating standalone scripts with inline dependency metadata (`uv init --script`), or managing the Python build backend (`uv_build`). Triggered by mentions of `uv`, inline script metadata blocks (`# /// script ... ///`), `uv.lock`, `pyproject.toml` with `[tool.uv]`, or any Python script Claude is about to run in a uv project.
