Clean Deadcode

Workflow

  1. •

    Determine the dead code analysis tool to use:

    • •Check project config files (AGENTS.md, CLAUDE.md, README, Makefile, etc.) for tooling conventions
    • •If not found, ask the user which tool to use
  2. •

    Run the tool and collect results.

  3. •

    Categorize findings by severity:

    • •SAFE: Unused utilities, helpers, test files
    • •CAUTION: API routes, components (may have external consumers)
    • •DANGER: Config files, main entry points (never delete)
  4. •

    Generate a report at .reports/dead-code-analysis.md with all findings and their categories.

  5. •

    Delete SAFE items only. For each deletion:

    • •Apply the change
    • •Run the test suite
    • •Roll back if tests fail
  6. •

    Summarize cleaned items and any CAUTION items for user review.

Hard Rule

Never delete code without running tests after each change.
