brain-memory SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
brain-memory from itechmeat/open-second-brain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Record taste signals and apply-evidence events into the Brain observing-memory layer of Open Second Brain. INVOKE this skill (and call `brain_feedback`) the moment the user expresses a preference, dislike, correction, or rule in dialogue — "don't do X", "use A instead of B", "I prefer Y", "X is wrong here", or any explicit imperative that should outlive the current turn. SEPARATELY invoke (and call `brain_apply_evidence`) right after you produce a durable artifact…
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 Memory
Brain is the agent-writable observing-memory layer of Open Second Brain. It accumulates user preferences from real signals and learns from real applications. Your job is to (a) record taste signals as they arrive in conversation, and (b) record whether you applied or violated active preferences each time you produce a durable artifact in a relevant scope. The deterministic `dream` pass turns repeat signals into rules and retires what stops being applied.
## When to call `brain_feedback`
Call **once per taste signal** the user (or a teammate agent) expresses. Concrete triggers:
- Explicit corrections: "don't do X", "stop doing Y", "use A instead of B".
- Stated preferences with outlasting reach: "I prefer X over Y", "expand acronyms on first use", "always include a CHANGELOG entry".
- Pushback on a specific artifact you produced that targets a *rule*, not a one-off ("this commit message is wrong — use imperative voice").
- A teammate agent or human describing a process rule in chat that should survive future sessions.

How to install
mdr add itechmeat/open-second-brain/brain-memory@sha256:ec1d3493f1c5f0ceThe line at the top of this page pins the label git:20261016.fd8a0c8, 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.
