What problem does it solve?
Modern Python projects need fast, reliable dependency installation, reproducible lockfiles, and simple virtual environment and Python version management to avoid slow installs, inconsistent builds, and dependency conflicts across development and CI/CD environments.
Core Features & Use Cases
- Fast dependency installation and resolution: ultra-fast installer and resolver for installing packages and generating uv.lock for reproducible builds.
- Virtual environment and Python version management: create and pin project Python versions, install interpreters, and manage isolated venvs seamlessly.
- Use Case: Initialize a new project, pin Python 3.12, add runtime and dev dependencies, generate a lockfile, and run tests in CI with frozen installs to ensure identical environments.
Quick Start
Use the uv-package-manager skill to initialize a project, pin Python 3.12, create a venv, add requests and pytest, and generate pyproject.toml and uv.lock.
