  Fast Python package and project management using Astral's uv. Use when
  installing packages, managing virtual environments, running Python scripts,
  or initializing Python projects. Triggers on: pyproject.toml, requirements.txt,
  Python dependency discussions, virtual environment setup.

Astral UV

UV is an extremely fast Python package installer and resolver written in Rust.

Quick Reference

TaskCommand
Create venvuv venv
Install packageuv pip install <pkg>
Add dependencyuv add <pkg>
Run scriptuv run <script.py>
Sync dependenciesuv sync
Init projectuv init

Project Management

Initialize a new project:

bash
uv init my-project
cd my-project

Add dependencies (updates pyproject.toml automatically):

bash
uv add requests httpx
uv add --dev pytest ruff

Sync environment with lockfile:

bash
uv sync

Running Code

Run scripts without manual venv activation:

bash
uv run python script.py
uv run pytest
uv run ruff check .

Run with inline dependencies:

bash
uv run --with requests script.py

Virtual Environments

bash
uv venv                    # Create .venv
uv venv --python 3.12      # Specific Python version

pip Interface

Drop-in pip replacement (10-100x faster):

bash
uv pip install requests
uv pip install -r requirements.txt
uv pip compile requirements.in -o requirements.txt

Python Version Management

bash
uv python install 3.12     # Install Python version
uv python list             # Show available versions
uv python pin 3.12         # Pin version for project

Best Practices

  1. •Prefer uv add over uv pip install for project dependencies
  2. •Use uv run instead of activating venvs manually
  3. •Commit uv.lock to version control
  4. •Use uv sync --frozen in CI for reproducible builds
  5. •Add dev dependencies with uv add --dev
