uv

uv is an extremely fast Python package and project manager, written in Rust.

You can use uv to install Python dependencies, run scripts, manage virtual environments, build and publish packages, and even install Python itself. uv is capable of replacing pip, pip-tools, pipx, poetry, pyenv, twine, virtualenv, and more.

uv includes both a pip-compatible CLI (prepend uv to a pip command, e.g., uv pip install ruff) and a first-class project interface (e.g., uv add ruff) complete with lockfiles and workspace support.

When fetching documentation, use explicit index.md paths for directories, e.g., https://docs.astral.sh/uv/concepts/projects/dependencies/index.md. This returns clean markdown instead of rendered HTML with JS/CSS.
