Your team's shared, AI-ready knowledge base — people, companies, meetings, SOPs, and decisions structured so an agent can answer on your team's behalf. Team-scope sibling to second-brain — personal notes go there, not here. Modes — capture, compile (wiki pages + INDEX.md), query (trust-weighted, saved to outputs/), review (verify / deprecate / supersede stale captures), lint, connect, search. Structured raw dirs (people/, companies/, meetings/, sops/, decisions/, customer-language/…
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
# /company-brain — Team-shared AI-ready knowledge base **Company Brain** *(n.)*: Your team's shared, AI-ready knowledge base — people, companies, meetings, SOPs, and decisions structured so Claude can answer questions on your team's behalf. Team-scope sibling to `second-brain` (personal-scope). Same core compile → wiki → outputs pattern; different raw schema optimized for multi-author, sales-heavy, ops-heavy team use. Also the operational backbone for the **Company Brain Setup** productized service (was previously called "Second Brain as a Service"; renamed to match the skill). ## Mental model Three layers, same as second-brain — but the raw/ layer is *structured*, not flat: ``` raw/ → wiki/ → outputs/ (structured (compiled (generated by category) interlinked) artifacts) ``` **Structured raw/ dirs** (each is its own top-level folder in the vault): | Dir | What lives here | |---|---| | `people/` | Contacts with context — CRM-lite. One markdown file per person. | | `companies/` | Org profiles — last touchpoint, opportunity size, status. One file per company. | …

How to install
mdr add coreyhaines31/makerskills/company-brain@sha256:953457f9dcce4bbbThe line at the top of this page pins the label v0.4.0, 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.
