uv (Python Package Manager)

uv is a fast Python package manager used by Science Skills to run their Python CLI scripts. Many skills depend on uv being installed and on PATH.

Ensure uv is available before running any skill that depends on it.

Setup

1. Check if uv is already available: uv --version If this succeeds, uv is

ready — skip the remaining steps.

1. Check whether uv is installed at its default location but not on PATH:

"$HOME/.local/bin/uv" --version If this succeeds, skip to step 4.

1. If uv is not installed do both these steps in order:

(a) Tell the user that uv is a tool for creating a consistent and reliable Python environment used for running the Science Skills, and that you need to install it now. (b) Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh

1. Add uv to PATH and verify (run as a single command): `export

PATH="$HOME/.local/bin:$PATH" && uv --version`

After setup, bare uv commands should work without repeating the export.
