Use when the user says brain, project knowledge, what do we know about, open tasks, or recent decisions, or runs /brain or /brain-update. SQLite project_brain.db tracker for entities, relationships, tasks, threads, decisions, events.

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 --- Project Knowledge Tracker

A structured SQLite database (`project_brain.db`) that lives in each project folder, replacing flat markdown memory files with queryable, relational knowledge.

# Initialize in current project folder
$BRAIN init

How to install

The exact contents, by fingerprint

mdr add coco-research/coco/brain@sha256:dbc1e1590c9b1dab

The line at the top of this page pins the label git:20260914.e75f220, 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.
