Sample marketing brain: our own site

company.md

• Name in the page title and Open Graph: Agent Tools. Source: Site Check check_page_tags on the home page.
• Name mismatch: the site calls itself OpenKrill, and llms.txt is titled Agent Tools. Source: SEO Audit check_ai_instructions, check name_consistency, status fail. The tool's fix: use the site's own name as the file title.
• What we sell: free MCP servers and data APIs for AI agents, and 23 fixed-price services that a person checks.
• Pay path, named the same way in every skill: the quote form, then escrow on Upwork or Deel.
• Customers and results: none claimed. The brain states only what the public pages show.

audience.md

• Free tools: a person who adds an MCP address to ChatGPT, Claude or Cursor.
• Paid services: the role on each service, such as IT admin, marketing lead or founder.
• Not proven: that companies hiring a "marketing engineer" will buy. The brain marks that as a guess.

brand.md

• Public title: Agent Tools. Company name: OpenKrill. Never mix the two in one sentence without saying both.
• Share image: https://tools.openkrill.app/og-v3.png, 1200 by 630. Source: check_page_tags.
• Voice sample: the "New services" note on the services page, 52 words. AI Text Check check_ai_writing: score 0, level low, 0 findings, rules version 1. A low score is not an authorship verdict.
• Words we use: tool, offer, quote, escrow, a person checks the result. Words we never use: guaranteed citations, we post for you, we log in to your accounts.

lessons.md

• AI crawlers: robots.txt has one rule, User-agent: * then Allow: /, so all 14 AI crawlers Site Check names may read the site, from GPTBot and ClaudeBot to PerplexityBot, Google-Extended and CCBot. Source: check_ai_crawler_access. It reads robots.txt only, not a firewall.
• llms.txt, llms-full.txt and the AI instructions page are found: 5 checks pass and 1 fails (the name mismatch above), 8 pages read.
• Home page: no short summary under the title, so the summary clarity check fails. The other 4 citation checks pass: author line, FAQ, headings and structured data. Source: Site Check ai_readiness_check.
• Campaign results: none. There is no ads data in this brain, so it names no winning ad.

skill.md

Name: openkrill-marketing-brain
When: the user asks for campaign context, an offer, a banned claim, or which public tool to call.
Read first: company.md, offers.md, audience.md, brand.md, lessons.md.
Never claim a citation, a revenue number or an ad result that is not in those files.
Never ask for an ads login, an analytics login or a GitHub token.
Tools, public, no key, 200 calls a day per network without a key:
- Site Check: https://sitecheck.openkrill.app/mcp
  Call check_ai_crawler_access and check_page_tags before a claim about a page.
- SEO Audit: https://seoaudit.openkrill.app/mcp
  Call check_ai_instructions with the domain, not a URL.
- AI Text Check: https://aitext.openkrill.app/mcp
  Call check_ai_writing on a draft of 40 words or more. A low score is not an authorship verdict.
- Post Kit: https://postkit.openkrill.app/mcp
  Call it only after offers.md names the product facts.
Before done:
- Every price matches offers.md.
- Every crawler claim names the date of the tool result.
- A person reads anything about taste, and any sentence about money.

What the checks found that a read by eye missed

We first wrote this brain by hand from the same pages. That draft missed the name mismatch, the missing summary under the home page title and the names of the 14 AI crawlers, and it judged the voice by eye. The three checks found all four in about one minute.
