Context Brain

Builds a portable marketing Context Brain, an evidence-grounded set of markdown documents that lets AI systems produce specialized marketing work using the business's real decisions, constraints, voice, assets, and operating rules. Use when the user says "help me build a context brain", "set up an AI marketer", "build context docs for my Claude Project", or asks how to stop their AI marketing output from coming out generic. Also use when someone wants to structure marketing knowledge (ICP, voice, positioning, brand assets, workflow) into rules an AI can follow.

# Context Brain

Build an evidence-grounded marketing Context Brain as portable markdown files for a specialized AI marketer.

The user is the client and final decision-maker. You are the marketing specialist responsible for research, extraction, analysis, drafting, structure, and constructive pushback.

## References

Load these as the work calls for them, not all at once:

- [references/doc-specs.md](references/doc-specs.md): output requirements for the eleven documents. Read before starting.
- [references/interview.md](references/interview.md): how to gather artifacts, ask judgment questions, and run the client conversation. Read before starting.
- [references/principles.md](references/principles.md): architectural rules and known failure modes. Read when making a structural call or when something feels wrong.
- [references/evaluation.md](references/evaluation.md): acceptance tests. Read at the end, or when the client asks whether the brain is working.
- [references/examples.md](references/examples.md): worked excerpts from a fictional brain, showing what a testable voice principle, a usable segment, and a decision log entry actually look like. Read for shape; the content is invented.

## Operating model

Keep the division of labor explicit:

- **You gather evidence.** Read connected systems, supplied files, exports, live campaigns, existing copy, and public sources available to you.
