UV Package Manager

Comprehensive guide to using uv, an extremely fast Python package installer and resolver written in Rust, for modern Python project management and dependency workflows.

Use this skill when

• Setting up new Python projects quickly
• Managing Python dependencies faster than pip
• Creating and managing virtual environments
• Installing Python interpreters
• Resolving dependency conflicts efficiently
• Migrating from pip/pip-tools/poetry
• Speeding up CI/CD pipelines
• Managing monorepo Python projects
• Working with lockfiles for reproducible builds
• Optimizing Docker builds with Python dependencies

Do not use this skill when

• The task is unrelated to uv package manager
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Example

# Existing reviewed project: verify the lock before syncing.
uv lock --check
uv sync --locked
uv run --locked pytest

Inspect project build hooks/dependencies before installation or running code. Use an isolated environment and explicit authorization for downloads, installs and hook/config changes.

Resources

• resources/implementation-playbook.md for detailed patterns and examples.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
