What it does

Uv is an agent skill from OpenHands/extensions. If the project uses uv, use this skill. Use this skill to create/manage Python projects and environments with uv, add/remove dependencies, sync a project from uv.lock, and run commands in the project environment.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `.plugin/plugin.json`, `README.md` and `references/README.md`).

It works with Python. The repository describes itself as: Public registry for OpenHands extensions. The licence is MIT.

Requirements

Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit d008b81. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- uv
- curl
- sh
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- astral.sh
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Uv loads about 660 tokens when it runs, and up to ~694 if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 199 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~55
When it runs · the whole SKILL.md, loaded when a task matches: ~660
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~694

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: uv
description: If the project uses uv, use this skill. Use this skill to create/manage Python projects and environments with `uv`, add/remove dependencies, sync a project from `uv.lock`, and run commands in the project environment.
triggers: uv, uv.lock

uv (Python)

Use uv as the default tool for Python dependency + environment management when the repo has uv.lock, mentions uv in its docs/Makefile, or already uses a .venv created by uv.

Quick decision rules

If the repo has uv.lock and pyproject.toml: treat it as a uv-managed project.
If the repo has only requirements.txt: you can still use uv pip for fast installs.
Prefer project commands (uv add/remove/sync/run/lock) over raw pip unless the repo explicitly uses uv pip.

Installation (if needed)

Prefer a packaged install method when available. If you use the official installer, review it first (avoid blindly piping into a shell) and follow the latest instructions in the official docs.

bash

# macOS/Linux (official installer)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell, official installer)
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Common operations

Initialize a new project

bash

uv init
# or
uv init my-project

Create / use a virtual environment

bash

uv venv  # creates .venv

# If you need a specific version, match the project's declared requirement
# (e.g., pyproject.toml / CI config), not an arbitrary latest version.
uv venv --python 3.x

# optional activation (not required for uv commands)
source .venv/bin/activate  # macOS/Linux
# .venv\\Scripts\\activate   # Windows

Add / remove dependencies (updates pyproject.toml and uv.lock)

bash

uv add requests
uv add 'requests==2.31.0'
uv add -r requirements.txt

uv remove requests

Lock + sync (reproducible installs)

bash

uv lock   # (re)generate uv.lock
uv sync   # create/update .venv to match uv.lock

If you pulled new changes and uv.lock changed, run uv sync.

Run commands inside the project environment

bash

uv run python -m pytest -q
uv run python main.py
uv run ruff check .

Using uv as a fast pip replacement (requirements workflows)

bash

uv venv
uv pip install -r requirements.txt
uv pip freeze
uv pip list

Notes / pitfalls

uv will usually auto-detect and use .venv in the project root.
In CI/containers you may see uv pip install --system, but prefer virtualenvs for local dev.
If a command mutates deps, prefer uv add/remove/lock/sync so uv.lock stays correct.

Questions about Uv

What does Uv do?

If the project uses uv, use this skill. An agent skill from OpenHands/extensions. Uv is an agent skill from OpenHands/extensions. If the project uses uv, use this skill.

When should I use Uv?

Uv fits situations like: create/manage Python projects and environments with uv; add/remove dependencies; sync a project from uv.lock; run commands in the project environment.

How do I install Uv in Claude Code?

Run `npx skills add OpenHands/extensions --skill uv -a claude-code`. Or copy the skill folder (skills/uv in OpenHands/extensions) into .claude/skills/uv in your project. Claude Code loads it when a task matches its description.

How do I install Uv in Codex?

Run `npx skills add OpenHands/extensions --skill uv -a codex`. Or copy the skill folder (skills/uv in OpenHands/extensions) into .agents/skills/uv in your project. Codex loads it when a task matches its description.

Can I use Uv in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add OpenHands/extensions --skill uv -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/uv, .gemini/skills/uv, .github/skills/uv and .opencode/skills/uv in your project.

What does Uv need to run?

Going by SKILL.md and its folder, Uv needs the command-line tools its instructions call (uv, curl and sh). Our summary lists: Python 3.

Does Uv access the network?

SKILL.md names 1 domain. In commands or code: astral.sh; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.

Is Uv safe to install?

Our automated static check of SKILL.md found notes only (pipes a well-known installer script into a shell), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Uv use?

Uv is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Uv use?

About 660 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 34 tokens, read only when the agent opens those files.

What are the alternatives to Uv?

Skills that share tags, products or a category with Uv: MCP Server Builder (anthropics/skills, 180k stars), PDF Processing (anthropics/skills, 180k stars), NotebookLM Research Assistant (PleasePrompto/notebooklm-skill, 7.8k stars) and Manim Video Production (browser-use/video-use, 28k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Uv?

OpenHands (a GitHub organization) maintains it in OpenHands/extensions, which has 157 GitHub stars. The repository holds 78 skills in this directory. The repository was last updated on October 6, 2026.

Source: OpenHands/extensions on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
