brain:rescan from coco-research/coco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when project files changed since the last brain scan, CLAUDE.local.md was updated, or a periodic refresh is due. Rescans incrementally, writes new entities, decisions, and documents; needs project_brain.db (run /brain-init first).
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:rescan --- Incremental Knowledge Rescan
Detects what changed since the last scan and updates the brain DB with new knowledge.
## Prerequisites
- `project_brain.db` must exist in the project folder (or parent). If not found, tell the user: "No brain DB found. Run `/brain-init` first."
- At least one project must exist in the DB.
## Procedure
### Step 1: Run the scanner
```bash
python3 ~/.claude/skills/brain/scripts/brain/brain_cli.py scan
```
Check the output:
- If `is_first_scan: true` → this folder was never scanned. Tell the user and proceed with full scan.
- If `new_files: 0` and `changed_files: 0` → "Everything up to date. No changes since last scan ({last_scan})." → done.
- Otherwise, show the delta:
```

How to install
mdr add coco-research/coco/brain:rescan@sha256:00f1df4be09783e3The 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.
