What problem does it solve?

This Skill emphasizes safety when modifying untested legacy code by adding characterization tests first and following the RGR workflow.

Core Features & Use Cases

  • Characterization Testing: Write tests that document existing behavior before making changes.
  • Red/Green/Refactor Flow: Use a safe loop to red, green, and refactor with confidence.
  • Risk Mitigation: Prevent hidden regressions by anchoring changes to real behavior.

Quick Start

Identify a legacy function, write baseline characterization tests, run tests to confirm baseline, then proceed with small changes.
