# Refactoring.Guru Skill

Use this skill when a task involves diagnosing smells, choosing targeted refactoring treatments, preserving behavior, applying a refactoring catalog, or avoiding uncontrolled redesign.

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