description	Python dependency management with pip and venv. Use this skill when working in a Python project that uses pip, requirements.txt, setup.py, or pyproject.toml without uv.lock. Also use when the user mentions pip, venv, virtualenv, or asks about Python dependency management in a traditional pip-managed project. Provides dependency management patterns and quality gate commands for pip workflows.

Dependencies

• Pin versions in pyproject.toml for applications
• Use version ranges for libraries
• Separate dev dependencies via [project.optional-dependencies]

Quality Gates (pip)

Before considering any code complete, MUST complete all steps:

1. Tests with Coverage

   • pytest — all tests pass
   • pytest --cov — coverage above threshold (MANDATORY)
   • Debug: pytest path/to/test.py -v or pytest --lf

2. Linting with ZERO warnings

   • ruff check src — zero warnings (MANDATORY)
   • ruff format src — consistent formatting
   • McCabe complexity <= 10

3. Security Audit

   • pip-audit — check for known vulnerabilities (MANDATORY)
   • pip list --outdated — check for outdated dependencies

4. Documentation Sync

   • mkdocs build — verify docs build
   • Ensure examples match current implementation
