The brief is the bottleneck
Five questions, answered from validated evidence. A promise you can prove false in ninety days. Receipts, not adjectives.
Your job: turn the five-question brief into a first draft that starts from evidence, not a blank page.
Draft my landing page Pull my voice profile, offer, competitive landscape, segments, and recent interviews over MCP — and my design system, so the page wears my actual brand. Draft a landing page for my committed segment around a single falsifiable promise and one CTA. Pull the problem language from real interviews — quote the validated pain, don't invent it — and match the proof to the shape of the promise. claude mcp add --transport http leanspark https://leanspark.ai/mcp Connect first →
What you get back
Drafts a starting page from your brief — hero, problem, proof, one CTA — in your own voice and pulled from your canvas, your interviews, and your proof, so the copy starts from validated context instead of a blank page.
A page draft (hero / problem / solution / proof / CTA) in your voice, built around one falsifiable promise. You wire it up and ship it.
A landing page is easy to write and hard to get right, and the difference is almost never the design. It’s the brief. Before a word of copy, answer five questions — and answer them from evidence, not from your own head:
- Who is this for? — a validated segment, not “everyone.”
- What problem are they here to solve? — in their language, from your interviews.
- What promise does this page make? — specific enough to be proven wrong.
- What proof makes the promise believable? — receipts, not adjectives.
- What is the single CTA? — one. Not three, not “or.”
Make the promise falsifiable. A falsifiable promise is one where, ninety days out, you can say plainly “it held” or “it broke.” “Grow your business faster” is not falsifiable — you can spin any quarter into either answer. That’s not a promise, it’s a vibe. “Go from ten customers to fifty in ninety days” is falsifiable. Either you did or you didn’t.
And once the promise is specific, the proof has to match its shape. If the promise is “your team stops missing release deadlines,” the proof is receipts on release deadlines — a named customer, the releases-per-quarter before, the number after. Adjectives don’t convert. Receipts do.
