Python Package Management with uv

This workspace exclusively uses uv for Python package management, dependency resolution, and virtual environment handling. Never fall back to pip or python -m venv unless uv explicitly fails.

Rules

Package Installation

  • NEVER use pip install
  • ALWAYS use uv add <package> (for pyproject.toml-managed projects) or uv pip install <package> (for ad-hoc installs)

Virtual Environments

  • NEVER use python -m venv
  • ALWAYS use uv venv to create virtual environments

Dependency Resolution

  • Use uv pip compile to generate lockfiles (requirements.txt or uv.lock) instead of pip freeze

Project Initialization

  • Use uv init when initializing a new Python project

Performance

  • Assume uv is available; do not fall back to pip unless uv explicitly fails
