UV Global

Create and reuse a global uv environment at ~/.uv-global so you can install Python dependencies for quick, ad hoc scripts without polluting the system interpreter.

Lightning-fast setup that keeps one shared virtual environment ready for temporary tasks.

Use this skill when the user needs Python packages (data processing, scraping, etc.) that are not preinstalled and a full project-specific environment would be overkill. Skip this if the user explicitly wants system Python or a project-local venv.

Requirements

uv available. If missing, you need either brew (macOS/Linux) or curl to install it.

Installation

bash

bash ${baseDir}/uv-global.sh

The script will:

•install uv via brew (macOS/Linux) or the official curl installer if uv is absent
•create a global uv project at ~/.uv-global
•create a virtual environment with common packages in ~/.uv-global/.venv

Optionally prepend the venv bin to your PATH so python defaults to the global env:

code

export PATH=~/.uv-global/.venv/bin:$PATH

Usage

For any quick Python script that needs extra dependencies:

bash

# install required packages into the global env
uv --project ~/.uv-global add <pkg0> <pkg1> ...

# write your code
touch script.py

# run your script using the global env
uv --project ~/.uv-global run script.py

Tips:

•Keep scripts anywhere; the --project ~/.uv-global flag ensures they run with the global env.
•Inspect installed packages with uv --project ~/.uv-global pip list.
•If a task grows into a real project, switch to a project-local venv instead of this global one.
