This skill should be used when the user asks to clean up or simplify a codebase; find dead code, dead features, orphaned files, stale configuration, or unused dependencies; detect duplicate or split-brain implementations, authorities, caches, parsers, validation, or lifecycles; finish a partial migration; remove speculative abstractions or misleading comments; or perform an exhaustive every-file cleanup audit. Also trigger when cleaning AI-generated code, agent trajectory residue, hallucinated…
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
# Code Cleanup Understand the whole product before judging its code: who uses it, what they need, its functional and non-functional goals, boundaries, supported workflows, non-goals, and pivots. Review every relevant file in that product boundary, including cooperating repositories. Dead code often sits outside recent changes. Follow features through construction, state, persistence, protocols, deployment, recovery, tests, settings, assets, scripts, and documentation. Look beyond unused symbols. Find code that compiles, runs, or passes tests but no longer helps the product; complete dead feature islands whose members keep one another looking alive; split-brain implementations and parallel lifecycles; half-removed features; abandoned optimizations and future-proofing; dead members hidden in large files; misleading comments; unused packages, imports, features, configuration, environment variables, defaults, and settings; and residue left by an agent's abandoned approaches. Tests, helpers, and comments inside a dead island do not prove that it is alive. Zoom out until the product responsibility is clear, then be willing to delete …

How to install
mdr add johnkozaris/jko-claude-plugins/code-cleanup@sha256:27559fb6bb88bceeThe line at the top of this page pins the label git:20260823.7b6e838, 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.
