About uv

A setup skill for uv, the Python package manager used to run Science Skills’ Python CLI scripts. It checks for an existing installation, provides installation instructions, and helps make uv available on PATH.

Key features

  1. 01Check whether uv is available
  2. 02Install uv when needed
  3. 03Add uv to PATH and verify

Use cases

  1. 01Prepare an environment for Science Skills scripts
  2. 02Resolve uv availability before running a skill

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/google-deepmind/science-skills --skill uv

After installing, type/uvin Claude Code to confirm it loaded.

Details

From the project README

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 (or & uv --version in PowerShell). If this succeeds, uv is ready — skip the remaining steps.

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

    • Unix/macOS: "$HOME/.local/bin/uv" --version
    • Windows (PowerShell): & "$HOME\.local\bin\uv.exe" --version

    If either succeeds, skip to step 4.

  3. If uv is not installed do 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:

    -   **Unix/macOS**: `curl -LsSf https://astral.sh/uv/install.sh | sh`
-   **Windows (PowerShell)**: `powershell -ExecutionPolicy ByPass -c
    "irm https://astral.sh/uv/install.ps1 | iex"`

  4. Add uv to PATH and verify (run as a single command):

    • Unix/macOS: export PATH="$HOME/.local/bin:$PATH" && uv --version
    • Windows (PowerShell): $env:PATH = "$HOME\.local\bin;" + $env:PATH; uv --version

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