python-uv

What problem does it solve?

This Skill addresses the common pain points in Python development: slow dependency resolution, inconsistent environments, and non-reproducible builds caused by fragmented tooling (pip, venv, pip-tools). It enforces uv as the single, fast, and reliable solution for package management, ensuring consistent and efficient workflows.

Core Features & Use Cases

• Unified Package Management: Replaces pip, virtualenv, and pip-tools with uv for environment creation, dependency installation, and package locking.
• Reproducible Environments: Generates and uses uv.lock to pin exact dependency versions, guaranteeing consistent builds across all environments (local, CI, production).
• Fast Command Execution: Runs all Python commands (pytest, ruff, mypy) through uv run, leveraging uv's speed and caching for rapid feedback.
• Use Case: When onboarding to a new Python project, simply run uv venv .venv && source .venv/bin/activate && uv sync to set up a fully reproducible and optimized development environment in seconds.

Quick Start

To set up a new Python virtual environment and install dependencies using uv, run 'uv venv .venv && source .venv/bin/activate && uv sync' in your project directory.
