Health-check the second brain so failures are not silent: is the local search server alive, is the RAG index fresh, is the session-memory ledger filling, did the nightly distillation run. Read-only, with a green/red verdict per component. Triggers: "/brain", "/memory", "is the reindex alive".
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
# /brain — second-brain health at one glance > 🧒 When reporting to a non-technical operator, end with a short plain-words recap (rule `eli5-always`). Catches SILENT breakage of the memory/RAG stack (the things that kept breaking month after month: the reindex, the local search server, the memory pilot). Read-only, 0 tokens. ## What it does (one script) `python $IMPORTS_ROOT/brain_health.py` Checks 5 things and colors them 🟢/🟡/🔴: 1. **Search server** on its local port — alive or not (if it's down, auto-recall silently disappears); also shows whether the graph-assisted mode is on. 2. **Index** `_brain_e5.npy` — how fresh (🟡 if the reindex lags >48h). 3. **TurnState ledger** — how many turns recorded (memory Phase 1), when the last one was. 4. **Nightly distillation** — candidates in quarantine + when the last run happened. 5. **A/B direct-vs-graph recall** — how many runs + the operator's verdicts (👍/👎). Writes a dashboard `$OBSIDIAN_VAULT/_Dashboards/Brain-Health.html` (the operator reads with their eyes, [[prefer-visual-dashboards]]). Exit code 0/1/2 = ok/warn/red (for scripts). ## When to fix (on 🔴/🟡) …

How to install
mdr add tonydzi/second-brain-starter-kit/brain@sha256:749a68df22f25f22The line at the top of this page pins the label git:20261007.cd6c208, 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.
