pip

Use this skill for Python dependency management with safe defaults and reproducible results.

Scope

• Create and maintain project-local virtual environments
• Install, upgrade, uninstall, and inspect Python packages
• Manage requirements.txt and lock-like pinned outputs (pip freeze)
• Troubleshoot common pip failures (externally-managed-environment, resolver conflicts, wheel/build failures)

Safety Defaults

• Prefer isolated installs:
  • project: python3 -m venv .venv
  • app CLI: pipx (if available)
• Avoid global installs unless user explicitly asks.
• Prefer python3 -m pip ... instead of bare pip to avoid interpreter mismatch.
• Never run unknown setup.py or arbitrary install scripts without explicit user approval.
