Company Brain (Team Knowledge Base)

A team-shared, AI-ready markdown knowledge base of people, companies, meetings, SOPs and decisions that Claude can query on your team's behalf.

What it does

Turns scattered team knowledge into a structured markdown vault Claude can reason over.

  • Structured raw dirs: people/, companies/, meetings/, sops/, decisions/, customer-language/, recurring-questions/, sales-objections/ — captures are auto-routed by content type
  • Seven modes: capture (fast intake) / compile (build interlinked wiki pages + INDEX.md) / query (answer from the corpus, saved to outputs/) / review (triage: verify / deprecate / supersede) / lint (13 checks for orphans, staleness, contradictions, gaps) / connect (wikilink suggestions) / search
  • Multi-author discipline: every file stamps author, captured, trust, sensitivity; append and attribute rather than overwrite
  • Trust levels: unreviewed / verified / deprecated / superseded, so wrong info never gets full weight as context — deprecate instead of delete
  • Optional auto-sync: Fathom/Gong/Granola transcripts, Slack/email exports, CRM (HubSpot/Attio/Pipedrive)

Who it's for

  • Startup teams whose call notes, customer quotes and objections live scattered across Slack and Notion
  • Sales, CS and ops groups constantly asking "who's the internal expert on this?"
  • Teams already in Obsidian or Git-backed markdown who want a Claude-native alternative to Glean or Notion AI
  • Anyone running personal second-brain who needs a separate team-scoped vault

Examples

  1. /cb capture — paste a call transcript and it lands in meetings/2026-06-15-acme-discovery.md with author, date and trust: unreviewed.
  2. /cb query what does the team know about Acme's pricing objection? — cross-references the company profile, meeting notes and objection library, and warns "low confidence" when sources are unreviewed.
  3. /cb review — walks the unreviewed queue one file at a time (verify / deprecate / supersede) and recompiles affected wiki pages with an audit trail in outputs/.
  4. /cb lint — surfaces customer files untouched for 6+ months, questions asked 5+ times with no SOP, and single-contributor bus-factor risk.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/company-brain folder from the GitHub repo coreyhaines31/makerskills into my ~/.claude/skills/company-brain/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/coreyhaines31/makerskills.git && mkdir -p ~/.claude/skills && cp -r makerskills/skills/company-brain ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/coreyhaines31/makerskills.git
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r makerskills/skills/company-brain ~/.claude/skills/ (also copy second-brain, loopify, and deep-research if you want the composed workflows).
  5. Pick a vault location. The default is ~/Documents/CompanyBrain; to change it, add export COMPANY_BRAIN_VAULT="$HOME/your/path" to your shell profile.
  6. Restart Claude Code, then run /cb capture or say "log this meeting in the team brain" to create your first entry.
  7. To lock in your team's schema, create a CLAUDE.md inside the vault — it takes precedence over the skill's bundled default schema.
