This skill assists in installing and configuring the Python environment using uv for fast package and project management.

When to Use This Skill

• User needs to set up Python development environment
• User wants to install or configure uv package manager
• User asks to initialize Python project

Prerequisites

• curl (macOS/Linux) or PowerShell (Windows).

Your Roles in This Skill

• DevOps Engineer: Install and configure Python environment using uv. Initialize Python projects with virtual environments. Manage Python versions and dependencies. Verify installations and troubleshoot setup issues. Update project documentation to reflect environment setup.

Role Communication

As an expert in your assigned roles, you must announce your actions before performing them using the following format:

As a {Role} [and {Role}, ...], I will {action description}

This communication pattern ensures transparency and allows for human-in-the-loop oversight at key decision points.

Instructions

1. Check Existing Installation

Before installing, check if uv is already installed.

uv --version

If installed, ask the user for confirmation before reinstalling or updating.

2. Install uv

macOS and Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

3. Initialize Project with uv

To initialize a new project or set up the current directory:

uv init

This will set up a virtual environment and pyproject.toml.

4. Python Version

uv manages Python versions automatically. The default targeted version is typically the latest stable or system default (e.g., Python 3.12).

To pin a specific version:

uv python pin 3.12

5. Save User Preferences

After successful installation, save the Python package manager preference to dev-swarm/user_preferences.md so future sessions remember to use uv.

Example:

Create or update dev-swarm/user_preferences.md with:

## Python Package Manager
- Use **uv** for all Python package operations
- Python version: 3.12+
