STUB — not yet hydrated for this project. Pull the agent infrastructure forward from the repo you adopted it from: diff since the watermark, triage commit by commit, port what applies. Hydration is the watermark at `.claude/skills/update-muthur/watermark.json` — the procedure below is usable as written. Use when the user says "update muthur", "update the agent infra", "sync muthur", "sync the source", or "/update-muthur".
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
> ⚠️ **STUB.** This skill has no watermark to run on. Before it can be invoked, > fill in `.claude/skills/update-muthur/watermark.json` — `lastSyncedSha` (the > source's HEAD when you cloned it), `lastSyncedAt`, `lineage` — and write > `divergence.md` beside it for whatever your repo took differently or declined. > `repo` already names the template, and needs changing only if you adopted from > a repo that itself adopted from it. Delete this banner once you have, and drop > `STUB` from the description above. If you took a one-time snapshot and do not > intend to re-sync, delete the skill instead. > > **Hydration here is a few JSON fields and a record, not a procedure.** Unlike > the other stubs, every step below this banner is usable exactly as written. ## What this skill is for A repo that took its agent infrastructure — `CLAUDE.md`, `.claude/`, `scripts/`, whatever else — from another repo has a **source** that keeps editing those files. This skill finds what changed there since the last sync, decides commit by commit what applies here, and ports the ones that do: _pull the vendored agent infrastructure forward from the repo I took it from._ …

How to install
mdr add vzakharov/muthur/update-muthur@sha256:48e4cc3b8ef9aebfThe line at the top of this page pins the label git:20261028.0345136, 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.
