Show HN: Refactoring Skill for Claude

I used some skills I picked up 20 years ago refactoring a huge and very messy codebase I knew nothing about and built a skill that allows Claude to do the same.

Seems to work really well by executing very small and very safe refactoring steps that don't break functionality.

Very curious to hear how this works on large codebases and in different circumstances and how else we can improve it so that refactoring becomes a solved problem.
