uv (Python)

Use uv as the default tool for Python dependency + environment management when the repo has uv.lock, mentions uv in its docs/Makefile, or already uses a .venv created by uv.

Quick decision rules

• If the repo has uv.lock and pyproject.toml: treat it as a uv-managed project.
• If the repo has only requirements.txt: you can still use uv pip for fast installs.
• Prefer project commands (uv add/remove/sync/run/lock) over raw pip unless the repo explicitly uses uv pip.

Installation (if needed)

Prefer a packaged install method when available. If you use the official installer, review it first (avoid blindly piping into a shell) and follow the latest instructions in the official docs.
