Brain health checks: back-link enforcement, citation audit, filing validation, stale info detection, orphan pages, and benchmarks. Use when asked to check brain health, run maintenance, or audit quality.
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 Skill Periodic brain health checks and cleanup. ## Contract This skill guarantees: - All health dimensions are checked (stale, orphan, dead links, cross-refs, backlinks, citations, filing, tags) - Each issue found has a specific fix action - Back-link iron law is enforced - Citation format is validated against the standard - Results are reported with counts per dimension ## Phases ### Ownership failures are an inspection boundary Routine maintenance, startup checks, `doctor --fix`, and a request to "fix what's broken" do not authorize writer topology changes. On `owner_unavailable` or a writer coordination refusal, inspect `gbrain sources writer status --brain <id> --json` on the selected host first and report the owner, epoch, enabled state and blocked recovery to the operator. Do not claim a checkout, activate managed mode, transfer an owner, replace identities, or remove ownership markers as a repair. Deliberate administration requires a separately approved topology change and the action-specific intent plus reviewed state precondition described in `docs/architecture/topologies.md`. Neither a TTY nor `--yes` nor …

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.
