Copy the prompt below. Paste it into Claude, ChatGPT, Cowork, or whatever AI you already use. It will interview you for about fifteen minutes, then hand you back a complete set of BCP files ready to publish at your domain. No signup. No account. Free forever.
This is a senior brand strategist, compressed into a single prompt. Paste it into any AI. It knows how to interview you, what to push back on, and exactly what files to produce.
You are helping me author a Brand Context Protocol (BCP) for my brand. A BCP is a set of markdown files that describe my brand in a way AI agents can read. Every agent in my marketing stack, every vendor platform, and every consumer-facing AI (ChatGPT, Claude, Perplexity, Gemini) that might talk about my brand. The spec lives at https://hellotacit.ai. I am adopting it.
Your job: interview me, then produce a complete BCP tree as seven markdown files I can publish at `mydomain.com/.well-known/brand.md` and `mydomain.com/.well-known/brand/*.md`.
## Interview rules: READ CAREFULLY
**ONE question at a time. Then STOP.** Do not write a second question. Do not preview. Do not summarize. After each question: STOP, wait for my reply, then ask the next one.
If you find yourself generating multiple questions in a single response, you are violating these rules. Stop after the first question mark.
## Part 0: What have you got? (ASK THIS FIRST)
Before the interview starts, ask me: **"What have you got?"**
Do I have existing brand documents, such as brand guidelines, strategy decks, mission/vision statements, a pitch deck, tone-of-voice docs, an 'About' page? Anything in writing that describes the brand already?
Offer three ways to share: paste text, upload files, or link to public URLs (my homepage, about page, blog).
If I share materials: read them carefully, pre-fill answers to the 18 interview questions, and only ask me about the gaps. Don't re-interview me on things you already know.
If I say "I don't have anything," start the interview at Question 1.
[... followed by 18 interview questions across Identity, Voice, Values, Boundaries, Claims, and Representation, plus the seven file templates. Full prompt is ~3,500 words. Copy the whole thing into your AI of choice.]
The AI will ask you eighteen questions across six parts. Answer them in your own words. Be specific. Vague inputs produce vague BCPs. A vague BCP does nothing for your brand.
You'll cover:
At the end, the AI gives you seven markdown files: a root brand.md plus six daughter files. That's your complete BCP tree.
The files need to live at yourdomain.com/.well-known/brand.md and yourdomain.com/.well-known/brand/*.md. Three paths to get there, depending on who's helping you:
Email your seven files to your dev team with a link to our publishing docs. Hosting is a ten-minute task for anyone who ships your website.
Read the docs →Fork our public template, drop your files in, deploy to Cloudflare Pages, Vercel, Netlify, or GitHub Pages. Full walkthrough in the docs.
See hosting options →Book a $1,500 Expert Session and a senior strategist will sharpen your BCP and get it live on your domain inside a week. No pressure. The self-serve path is real.
See our services →Prefer code to chat? Fork our reference repo, edit the seven files, push to your domain. The template is MIT-licensed and production-tested against our own BCP at hellotacit.ai/.well-known/brand.md.
Hosting specifics (MIME types, CORS headers, Cloudflare rules, DNS config) live in the docs.
The whole point is adoption. When your /.well-known/brand.md is live, tweet it. LinkedIn it. Tell your vendor platforms it exists. Every live BCP makes the standard a little more real for every brand that comes after you.
