Finds stale docs, comments, docstrings, and commented-out code, checks each against the actual code, then fixes or removes it. Auto-fixes the clear rot and surfaces judgment calls. Trigger on: "find stale docs", "doc rot", "are the docs current", "fix the README".
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
# Doc Rot
Documentation lies as the code moves on. This skill finds the lies and fixes them — across `*.md` files, inline comments, docstrings, and commented-out code. It's the docs counterpart to `dead-code-cleanup`, and it enforces the comment hygiene rules in the user's CLAUDE.md ("explain WHY not WHAT"; "one canon version per file"; "update existing docs, don't proactively create new ones").
For a broader sweep of dead variables, functions, files, or tests (not just docs and comments), use `dead-code-cleanup` instead.
The core discipline: **a doc isn't stale because it looks old — it's stale because it contradicts the code.** Ground every call against the actual codebase before flagging it. A "removed" symbol might just be renamed; a "broken" path might live elsewhere now.
## Pre-flight
Per the user's git workflow: `git fetch && git status`, confirm you're on the right base branch (`develop` if it exists, else `main`) and up to date. Then scope the doc set — don't boil the ocean. List what's in range (a directory, the README, the files a recent change touched) and confirm before sweeping a whole repo.

How to install
mdr add jerseycheese/agent-skills/doc-rot@sha256:358612add41b11a0The line at the top of this page pins the label git:20261016.04e815b, 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.
