Check the health of the GreyMatter installation and trunk — dead links, unindexed notes, broken hooks, stale state. Use when recall seems to return nothing, when notes are not being saved, when the user says GreyMatter "is not working", or before trusting the trunk for something important.
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
# Check the trunk and the wiring Two commands, and they answer different questions. Run both. ```bash brain selftest # is the ENGINE wired correctly? (hooks, links, permissions) brain doctor # is the TRUNK coherent? (dead [[links]], orphans, index gaps) ``` ## Reading the result - **selftest red** → the installation is the problem. Re-run `install.sh`; it is idempotent and repairs its own wiring. - **doctor red** → the notes are the problem. Dead `[[links]]` and notes missing from `MEMORY.md` are the two that actually cost recall. - **Both green but recall returns nothing** → the query, not the machinery. Try narrower terms; the ranking is lexical, so it matches words, not meaning. ## What not to conclude A silent hook is not a healthy hook. If notes are not being saved and both commands are green, check that the hooks are registered at all — a hook whose path no longer resolves does not fail loudly, it simply stops recording.

How to install
mdr add yuno15-bb/greymatter-engine/doctor@sha256:315062dbe5ed3a5eThe line at the top of this page pins the label git:20260927.31ac526, 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.
