Refactoring Guru

This skill should be used when the user says "refactor this", "fix this smell", "apply Extract Method", "apply [technique name]", "clean up this code", or passes a finding code from smell-scan (e.g. B1, D3, C2). Also trigger when the user wants to apply a specific refactoring.guru technique to a specific location, or to apply everything (or everything in a domain) flagged by a prior smell-scan. Carries each finding's technique, file, location, and smell context into a safe test → refactor → test → commit cycle, delegating edits to the refactoring-applier agent.

This skill should be used when the user says "scan this for smells", "audit this code", "what code smells does X have", "review this for quality issues", "find code smells in", or asks about the code quality of a specific file, function, or class. Covers the full refactoring.guru taxonomy of 26 smells across 5 categories, producing located, confidence-scored findings mapped to concrete refactoring techniques — not generic Clean Code advice.
