ALWAYS use this skill proactively for Consumer Affairs Django repositories (located in ../ca/ directory) when ANY of these occur - (1) After writing or modifying ANY Python code files in CA repos (2) After tests pass and before telling user work is complete (3) User mentions linting, formatting, ruff, code style, or code quality (4) After using the ca-django-tests skill successfully (5) Before preparing to commit code. This skill runs 'ca exec ruff format' and 'ca exec ruff check --fix' to ensure code quality. CRITICAL - Always run this automatically after code changes and before declaring work complete.

ALWAYS use this skill proactively for Consumer Affairs Django repositories (located in ../ca/ directory) when ANY of these occur - (1) User mentions coverage, codecov, test coverage, partial coverage, branch coverage, or uncovered lines/code (2) User asks to write tests, add tests, run tests, or fix test failures (3) User asks to implement features, fix bugs, or modify code in CA repos and tests are needed (4) User provides a file path containing 'test' or 'tests' in CA repos (5) After writing new code in CA repos that needs test coverage. This skill handles Django test execution using the 'ca magictest' command and ensures 100% code coverage for CI requirements.
