m0-remember from coco-research/coco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add coco-research/coco/m0-remember@git:20261007.272268bPins git:20261007.272268b in mdr.lock. Pin the fingerprint instead.

Use when the user says 'm0 remember', 'record what we did', 'note for next session' or 'write a checkpoint', or after finishing a step worth handing to the next session. Appends one entry to the M0 thread (re-sending writes a second entry unless you pass the same `id`).
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
# /m0-remember — Write to the Operational Thread
The write path for M0. One call appends one entry to the shared thread for a
project.
The token is read from ~/.coco/m0-token on each call; never print it.
## Quick Reference
```bash
M0="${COCO_M0_URL:-http://127.0.0.1:8000}"
curl -s -X POST "$M0/api/brain/checkpoint" \
-H 'Content-Type: application/json' \
-H "Authorization: Bearer $(cat ~/.coco/m0-token)" \
-d '{"project":"acme-web","kind":"step_done",
"text":"Fixed the token refresh race in the auth middleware.",
"next_step":"Add a regression test for two concurrent refreshes.",
"last_verified":"pytest tests/auth -q: 31 passed",
"source_tool":"claude_code"}'
```
If the MCP tool is wired (`/m0 mcp`), call `m0` in `remember` mode directly —
same endpoint, fewer moving parts.
## Fields
| Field | Required | What to put in it |
|-------|----------|-------------------|
| `project` | yes | The project key. Use one stable value per project — the repository or directory name is the usual choice. Getting this wrong splits the thread. |

How to install
mdr add coco-research/coco/m0-remember@sha256:46d3cfa128b8407cThe line at the top of this page pins the label git:20261007.272268b, 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.
