**What is the Company Brain?**

Company Brain is Tycoon's built-in organizational memory — a tagged document system where your AI team stores and retrieves everything it learns about your business. No separate wiki, no external knowledge base, no lost context between sessions.

**How it works**

Every piece of company knowledge is a **Doc** with tags that define what it is and who should read it:

| Tag type | Examples | Purpose |
|----------|----------|---------|
| **Persistent** | `persistent:user`, `persistent:company`, `persistent:priority` | Current truth — your preferences, company context, strategic focus |
| **Memory: Rule** | `memory:rule` | Future operating rules ("always check Vault before marking BLOCKED") |
| **Memory: Lesson** | `memory:lesson` | Past mistakes and corrections to avoid repeating |
| **Memory: Knowledge** | `memory:knowledge` | Reusable facts, methods, and insights |
| **Deliverable** | `deliverable` | Completed work artifacts — reports, audits, plans |

**What gets stored automatically**

- **Your preferences** — communication style, language, decision format, disliked defaults.
- **Business context** — company mission, product, target customers, brand voice, no-go zones.
- **Strategy & priorities** — current Goals, Projects, and strategic tradeoffs.
- **Lessons learned** — when an agent makes a mistake or discovers a better approach, it writes a memory doc so the whole team improves.

**How agents use it**

Before any substantive work, agents search the Company Brain: `tyctl doc search "<topic>" --tags persistent`. They cite relevant docs in their answers and write back new knowledge when they learn something durable.

> Astra manages the Company Brain automatically. You focus on decisions; the AI team handles the memory.

### FAQ

**Q: Do I need to write docs myself?**
A: No. The AI team writes and maintains docs automatically. Astra prompts you only for approval on high-stakes rules or strategy changes.

**Q: How is this different from a wiki?**
A: It's agent-native. Docs are structured (tagged, versioned, searchable) and agents write/read them as part of their workflow — no context switching, no copy-paste.

**Q: Can I search past conversations?**
A: Yes. Astra can search across all surfaces — docs, tasks, chat history, and assets — with `tyctl grep everything "<keyword>"`.

**Q: What about secrets and credentials?**
A: Those go in **Vault**, not Company Brain. Vault is a separate encrypted credential store.
