Checking Changes Run at the end of a work session or after completing a set of changes — not after every small edit. This runs formatting, linting, type checking, and unit tests on all uncommitted files (staged, unstaged, and untracked). Workflow 1. Run 2. If issues are found: - Fix the reported errors - Re-run - Repeat until all checks pass 3. Only consider work complete when succeeds Notes - E2E tests are not included by default; use to also run changed e2e tests - E2E snapshot mismatches can be ignored (they require manual updates) ---
