uv · harperreed — Claude Code skill: what it does, how to install

Q: How to install uv in Claude Code?

Run `npx skills add harperreed/dotfiles --skill uv -a claude-code`. This adds the instruction file to `~/.claude/skills/uv/SKILL.md`.

Q: What prerequisites are required?

The `uv` binary must be preinstalled and accessible in your `PATH`. The skill checks this upfront with `uv --version`.

Guides your AI agent through Python workflows using uv: dependency resolution, virtualenvs, PEP 723 scripts, CI, and multistage Docker builds.

What uv does

This skill equips coding agents with command patterns for uv instead of traditional pip or poetry setups. It covers project initialization, standalone PEP 723 scripts, and interpreter switching. It replaces multiple legacy tools at once.

It also details deployment workflows, including pinned GitHub Actions configurations and a multistage Dockerfile designed around layer caching. Without uv installed and available on your system PATH, the skill halts execution.

What it helps with

set up reproducible Python dependencies and uv.lock
write a multistage Dockerfile with uv layer caching
configure GitHub Actions tests using astral-sh/setup-uv
migrate project commands from pip, poetry, or pyenv to uv

Example prompts for the agent

Migrate this repository dependencies from poetry to uv
Generate a multistage Dockerfile for my app using uv sync --frozen
Add httpx to script.py using PEP 723 metadata format
