Apply named refactoring transformations to improve code structure without changing behavior. Use when the user mentions "refactor this", "code smells", "extract method", "replace conditional", "technical debt", "move method", "inline variable", "decompose conditional", or "clean up this messy code". Also trigger when cleaning up legacy code, preparing code for new features by restructuring, or identifying which transformation fits a specific code smell. Covers smell-driven refactoring, safe…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Refactoring Patterns Framework A disciplined approach to improving the internal structure of existing code without changing its observable behavior. Every refactoring follows the same loop: verify tests pass, apply one small structural change, verify tests still pass. ## Core Principle **Refactoring is not rewriting. It is a sequence of small, behavior-preserving transformations, each backed by tests.** You never change what the code does — only how it is organized. Big-bang rewrites fail because they combine structural change with behavioral change, making it impossible to know which broke things. **The foundation:** Bad code is a natural consequence of delivering under time pressure, not a character flaw. Code smells are objective signals of degraded structure; the smell catalog tells you *where* to look, and the refactoring catalog tells you *what to do*. ## Scoring **Goal: 10/10.** Score structural quality by how many of the eight [Quick Diagnostic](#quick-diagnostic) rows pass — `score = round(passed / 8 × 10)`, adjusting down when a single smell is severe. Bands: …

How to install
mdr add wondelai/skills/refactoring-patterns@sha256:e09d21bcca98b575The line at the top of this page pins the label v1.4.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
