Surgical code refactoring to improve maintainability without changing behaviour. Covers extracting functions, renaming variables, breaking down god functions, improving type safety, eliminating code smells, and applying design patterns. Less drastic than repo-rebuilder; use for gradual improvements.
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
# Refactor ## Overview Improve code structure and readability without changing external behaviour. Refactoring is gradual evolution, not revolution. Use this for improving existing code, not rewriting from scratch. ## When to Use Use this skill when: - Code is hard to understand or maintain - Functions/classes are too large - Code smells need addressing - Adding features is difficult due to code structure - User asks "clean up this code", "refactor this", "improve this" --- ## Refactoring Principles ### The Golden Rules 1. **Behaviour is preserved** - Refactoring doesn't change what the code does, only how 2. **Small steps** - Make tiny changes, test after each 3. **Version control is your friend** - Commit before and after each safe state 4. **Tests are essential** - Without tests, you're not refactoring, you're editing 5. **One thing at a time** - Don't mix refactoring with feature changes ### When NOT to Refactor ``` - Code that works and won't change again (if it ain't broke...) - Critical production code without tests (add tests first) - When you're under a tight deadline - "Just because" - need a clear purpose ``` --- ## Common Code Smells & Fixes …

How to install
mdr add marielynneblock/arcanum-artifex/refactor@sha256:9850a0e83d5f0c99The line at the top of this page pins the label git:20260710.0115f49, 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.
