Skill content

Safe refactor
Define behavior-preservation boundary and establish verification before structural edits.
- Keep feature changes outside refactor.
- Move one ownership boundary at a time.
- Preserve public interfaces, failure behavior, ordering, and compatibility unless explicitly scoped.
- Keep intermediate states buildable and testable.
- Avoid dependency or configuration growth without correctness need.
Run same proof after change. Stop when behavior matches and requested structure is achieved.
