# python-uv

Makes the agent manage Python packages through uv only, no pip or poetry. Useful when the project already runs on uv or when environments keep drifting apart.

## What it does

The skill installs one rule for the agent: every dependency operation goes through `uv`. Add a package with `uv add <package>`, drop one with `uv remove <package>`, reconcile the environment with `uv sync`. There is no fallback to `pip`, `pip-tools` or `poetry`, even when the familiar command looks shorter.

Standalone scripts get two options. Dependencies can live inside the file in a `# /// script` comment block with `requires-python` and `dependencies` fields, then run with `uv run script.py`. Or manage them from the shell: `uv add package-name --script script.py`, `uv remove package-name --script script.py`, `uv sync --script script.py`.

Make sure uv itself is installed — the skill describes working with it, not installing it. And if the project deliberately uses poetry, this rule fights your setup. Either skip the skill or move the project to uv.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill python-uv -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill python-uv -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill python-uv -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills python-uv
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill python-uv -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path python-uv
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill python-uv -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/Mindrally/skills/tree/HEAD/python-uv/SKILL.md

## When to use it
- lock Python dependencies in a single file
- add a package without touching pip
- run a script together with its dependencies
- declare dependencies inside a standalone script
- close the gap between local and CI environments

## Example prompts
- Add requests to this project with uv and sync the environment
- Put the dependencies in a script block in this file and run it with uv
- Remove numpy from the script dependencies and refresh the lock

# Python Package Management with uv

You are an expert in Python development with uv package management.

## Core Directive

All Python dependencies must be installed, synchronized, and locked using `uv`.

Never use `pip`, `pip-tools`, or `poetry` directly for dependency management.

## Dependency Management Commands

For standard projects:

```bash
uv add <package>
uv remove <package>
uv sync
```

## Script Management

Execute scripts with proper dependency handling:

```bash
uv run script.py
```

### Manual Inline Metadata Configuration

Scripts can specify dependencies via comment blocks:

```python
# /// script
# requires-python = ">=3.12"
# dependencies = [
#   "torch",
#   "torchvision",
#   "opencv-python",
#   "numpy",
#   "matplotlib",
#   "Pillow",
#   "timm",
# ]
# ///
print("some python code")
```

### CLI-Based Script Dependencies

```bash
uv add package-name --script script.py
uv remove package-name --script script.py
uv sync --script script.py
```

## Key Principles

1. Always use `uv` for all package operations
2. Prefer inline script metadata for standalone scripts
3. Use `uv run` to execute scripts with their dependencies
4. Keep dependencies locked and synchronized across environments
5. Never fall back to pip or other package managers
