# Refactoring Skill

Use this skill when a task involves behavior-preserving code improvement, code smells, small refactoring steps, test-backed cleanup, or separating refactoring from feature changes.

Before making design or code decisions, read and apply [refactoring.mini.md](refactoring.mini.md). Use [refactoring.md](refactoring.md) only as a deeper reference when the mini rules are not enough for the current refactoring tradeoff.
