概要
Legacy Code Safety provides a structured framework for Claude to handle high-risk modifications in codebases lacking test coverage. By enforcing the 'Golden Rule'—never modify untested code without adding tests first—this skill ensures that existing behaviors are documented through characterization tests before any logic is changed. It guides the user through the RGR (Red-Green-Refactor) workflow specifically tailored for legacy systems and offers advanced strategies like the Strangler Fig pattern to minimize regressions while managing technical debt in complex, production environments.
