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.

Tips for Safe Refactor

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • It is part of a pack with 22 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
