Skill Refactor

A user-invoked gate skill: forces any proposed refactor of an existing skill — token reduction, structure cleanup, dedupe, prose tightening — through a deletion-first design pass with automated output equivalence verification before the change is committed.

Overview

Skills accumulate tokens. SKILL.md files grow over rounds of edits. Most edits are additive — fixing a corner case here, adding an example there. The result: skills that take more tokens to load than they need to, with output behavior that's the same as before (or worse, since longer prompts can degrade focus).
