recall skillB
recall is agent-read markdown (skill) from yuno15-bb/greymatter-engine: Search the C Brain trunk for notes relevant to a subject, and read the ones that matter. Use when the user asks what they already know about something, wants past decisions on a topic, says "did we solve this before", "what do I have on X", "check my notes", or when a task smells like something already worked out once..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Recall from the trunk
Retrieve what is already known before working something out again.
## How
Run the recall, top 5, and read what comes back:
```bash
brain recall "$ARGUMENTS"
```
If `brain` is not on the PATH, the plugin ships it — call it directly:
`"${CLAUDE_PLUGIN_ROOT}/bin/brain" recall "$ARGUMENTS"`.
Each result gives a score, a note name and a path relative to the trunk
(`~/.c-brain/trunk`). **Open the ones above the noise floor and actually read
them** — the ranking is lexical, so it tells you where to look, never what is
true.
## Then
- Say what the notes establish, and cite each one by its path so the user can
check you.
- Say plainly when nothing relevant came back. A confident answer assembled
from three weakly-matching notes is worse than "the trunk has nothing on
this" — it looks like memory and is not.
- Never rewrite a note as a side effect of reading it.
## Scale
Recall holds well to about a thousand notes and degrades past that
(`tests/recall_benchmark.py` publishes the numbers). On a large trunk, prefer
several narrow queries over one broad one.Read the whole file at its exact version.
How to install
mdr add yuno15-bb/greymatter-engine/recall@git:20260729.12a9be5mdr add yuno15-bb/greymatter-engine/recall@sha256:32366e15f75a8fc3Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
