Audit and conservatively maintain a configured Yarbrain vault for structural errors, stale knowledge, duplication, conflicts, unprocessed evidence, and skill drift. Use periodically or when recall quality declines; make deterministic checks first and require approval for semantic consolidation or archival.
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
# Maintain a Yarbrain Wiki Keep the vault trustworthy without optimizing for fewer files or rewriting it for appearance. Treat an audit request as read-only. Write a report, rebuild an index, or change vault content only when the user also authorizes maintenance. ## Workflow 1. Resolve ../../scripts/yarbrain.py relative to this SKILL.md and run lint. Record missing structure, duplicate IDs, missing provenance, and broken links before using model judgment. 2. Count pending session records and identify episodes with no semantic or procedural consumer, notes past their freshness window, overlapping aliases, disputed claims, oversized index content, and skills contradicted by newer successful episodes. 3. Classify each proposed change as fix-structure, merge, split, supersede, archive, reverify, or promote-procedure. Route procedure work to procedure-promote and semantic changes or disputes to wiki-reconcile. Leave ineligible procedure candidates unchanged and report them as deferred. 4. Present every proposed mutation for approval, including structural fixes, semantic changes, index or report writes, and archival. Never delete the only …

How to install
mdr add yarlson/yarstack/wiki-maintain@sha256:70c209cf66b95746The line at the top of this page pins the label git:20260809.f078c7a, 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.
