Refactor Clean

Safely identify and remove dead code with test verification:

  1. Run dead code analysis tools:

    • knip: Find unused exports and files
    • depcheck: Find unused dependencies
    • ts-prune: Find unused TypeScript exports
  2. Generate comprehensive report in .reports/dead-code-analysis.md

  3. Categorize findings by severity:

    • SAFE: Test files, unused utilities
    • CAUTION: API routes, components
    • DANGER: Config files, main entry points
  4. Propose safe deletions only

  5. Before each deletion:

    • Run full test suite
    • Verify tests pass
    • Apply change
    • Re-run tests
    • Rollback if tests fail
  6. Show summary of cleaned items

Never delete code without running tests first!
