Build the business "brain" every marketing agent reads first — START-HERE, customer-fit, offers, voice, founder opinions, failed campaigns — by interviewing you and seeding it from your CRM (HubSpot, Pipedrive or Upsales), store (Shopify or WooCommerce) and Stripe, stored in the Cogny context tree.
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
# Marketing Brain People spin up ten agents, get a mountain of generic copy back, and decide AI marketing is overhyped. The agents were fine. The context was thin. This skill writes the onboarding doc you'd give a sharp new hire, and every other agent in `/marketing-engineer` reads it before doing anything. **Requires:** Cogny ($9/mo) for storage in the context tree and CRM/Stripe seeding. Without Cogny, the skill writes the same files to `./brain/` locally. ## Usage - `/marketing-brain` or `/marketing-brain build` — full build (≈60–90 min of interview, can be split) - `/marketing-brain section voice` — (re)build one section - `/marketing-brain review` — check every section for vagueness and staleness - `/marketing-brain promote brain/evidence/customer-language/2026-10-06` — move a proven finding from evidence into company policy (human-approved) ## The six files that do most of the work | Node | What it answers | Bad (useless to an agent) | Good | |------|-----------------|---------------------------|------| | `brain/START-HERE` | What we do, for whom, this quarter's priorities, where everything lives | — | One page, links to every node | …

How to install
mdr add cognyai/claude-code-marketing-skills/marketing-brain@sha256:01b4ae876831f8cfThe line at the top of this page pins the label v1.1.3, 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.
