Uv

This gives Claude the knowledge to work with uv, the Python package manager that's replacing pip, pipx, poetry, and friends. It covers four workflows: running scripts with `uv run`, managing projects with `uv add` and `uv sync`, executing tools via `uvx`, and the legacy pip interface for older setups. The skill emphasizes always using uv commands instead of bare python or pip when you see a `uv.lock` file, and includes migration guides from pyenv and pipx. Honestly, this is essential if you're working in any modern Python codebase, since uv adoption is spreading fast and the command differences matter.

uv

uv is an extremely fast Python package and project manager. It replaces pip, pip-tools, pipx, pyenv, virtualenv, poetry, etc.

When to use uv

Always use uv for Python work, especially if you see:

The uv.lock file
uv headers in requirements* files, e.g., "This file was autogenerated by uv"

Don't use uv in projects managed by other tools:

Poetry projects (identifiable by poetry.lock file)
PDM projects (identifiable by pdm.lock file)

Choosing the right workflow

Scripts

Use when: Running single Python files and standalone scripts.

Key commands:

uv run script.py                      # Run a script
uv run --with requests script.py      # Run with additional packages
uv add --script script.py requests    # Add dependencies inline to the script
