## What it does

The skill fires when a conversation touches uv, new Python projects, dependencies, lockfiles or `pyproject.toml`. The agent gets a cheat sheet for `uv init`, `uv add`, `uv remove`, `uv lock` and `uv sync`, with command forms and the directory layout uv creates on its own.

A routing table sits inside. Everyday dependency work belongs here; running one-off scripts, git and path dependencies, workspaces and interpreter versions get handed to sibling skills. There is a `pyproject.toml` template with `[project]` and `[build-system]` sections, plus examples of dependency groups: `--dev` for tests and linters, `--group docs` for documentation.

Tool access is narrow: `Bash`, `Read`, `Grep`, `Glob`. The skill installs nothing itself, so a working `uv` on the machine is a prerequisite — without it the commands in the cheat sheet go nowhere. For CI, `uv lock --frozen` and `uv sync --locked` matter: the second one fails when the lockfile is stale, which is your cue to check whether `uv.lock` was committed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill uv-project-management -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/uv-project-management/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/uv-project-management/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill uv-project-management -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/uv-project-management/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill uv-project-management -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/uv-project-management/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install laurigates/claude-plugins uv-project-management
```

2. **Manually: put the files in place**
- File: `.github/skills/uv-project-management/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill uv-project-management -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/laurigates/claude-plugins --path python-plugin/skills/uv-project-management
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/uv-project-management/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add laurigates/claude-plugins --skill uv-project-management -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/laurigates/claude-plugins/tree/HEAD/python-plugin/skills/uv-project-management/SKILL.md

## When to use it
- scaffold a new Python project in one command
- add a version-pinned dependency without breaking the lockfile
- move packages from `requirements.txt` into `pyproject.toml`
- upgrade a single library and leave the rest alone
- fail a CI job when the lockfile drifts from the environment

## Example prompts
- init a new Python project with uv and add pytest
- add fastapi and uvicorn to the project dependencies
- upgrade only requests in uv.lock and sync the environment

# UV Project Management

Quick reference for UV project setup, dependencies, and lockfiles.

## When to Use This Skill

| Use this skill when... | Use a focused sibling instead when... |
|---|---|
| Running `uv init`, `uv add`, `uv remove`, `uv lock`, or `uv sync` for everyday dependency management | Running a script or one-off command — use uv-run |
| Authoring or editing pyproject.toml `[project]` and `[tool.uv]` sections | Wiring git/path/editable deps or workspace inheritance — use uv-advanced-dependencies |
| Bootstrapping a new single-package Python project | Splitting a repo into multi-package workspaces — use uv-workspaces |

## When This Skill Applies

- Initializing new Python projects (`uv init`)
- Adding, removing, or updating dependencies (`uv add`, `uv remove`)
- Managing lockfiles (`uv lock`)
- Syncing project environments (`uv sync`)
- Configuring pyproject.toml

For running scripts, see **uv-run** skill.

## Quick Reference

### Project Initialization

```bash
# Create new project with complete structure
uv init my-project
cd my-project

# Initialize in existing directory
uv init

# Initialize with specific Python version
uv init --python 3.11 my-app
```

### Dependency Management

```bash
# Add dependencies
uv add requests
uv add 'flask>=2.0'
uv add 'django>=4.0,<5.0'

# Add development dependencies
uv add --dev pytest pytest-cov black

# Add optional dependency groups
uv add --group docs sphinx sphinx-rtd-theme

# Remove dependencies
uv remove requests flask

# Migrate from requirements.txt
uv add -r requirements.txt
```

### Lockfile Operations

```bash
# Create/update lockfile (uv.lock)
uv lock

# Lock with upgraded packages
uv lock --upgrade-package requests
uv lock --upgrade

# Lock without installing (CI/CD)
uv lock --frozen
```

### Environment Synchronization

```bash
# Sync environment to lockfile
uv sync

# Sync without updating lockfile
uv sync --frozen

# Error if lockfile is out of date
uv sync --locked
```

## Project Structure

UV projects follow this standard structure:

```
my-project/
├── pyproject.toml      # Project metadata and dependencies
├── uv.lock            # Locked dependency versions
├── .venv/             # Virtual environment (auto-created)
````
