SCRIPTED DEMOTask — Design a landing page hero for a fintech app.

Same model. Same task. Different director — different product.

THE MISTAKEVAGUE
Make me a landing page hero for a fintech app.
THE DIRECTION
Design a landing page hero for a fintech app.
+ AUDIENCEFirst-time investors who find finance intimidating.
+ TONECalm, reassuring — never salesy.
+ VOICESpeak to their fear, not their greed.
THE COST —No who → the AI designs for everyone. Designing for everyone is designing for no one.
PRINCIPLE 02 — REFRAME BEFORE SOLVING.
REF — ANTHROPIC · THE PROMPTING PLAYBOOK: define the role before the task, or the model guesses the who. https://youtu.be/G2B0YWuJUgI
MISTAKE.02 — NO CONSTRAINTSANALYSIS
02 / THE SKILL

Constrain with taste. Vague taste gets vague output.

THE MISTAKEVAGUE
Make it look nicer. More modern. More premium.
THE DIRECTION
+ CONSTRAINTDark #0A0A0A. Typography-led. One accent color max.
+ TASTENo stock photos, no gradients, no generic fintech blue.
+ REFERENCEReference: Linear’s restraint — not Stripe’s gloss.
THE COST —‘Make it pretty’ → the model reaches for the average of everything it has seen. The average is the slop.
PRINCIPLE 01 — DIRECT THE TOOLS, KEEP THE TASTE.
REF — ANTHROPIC · THE PROMPTING PLAYBOOK: constraints are the brief. An output contract beats a paragraph of adjectives. https://youtu.be/G2B0YWuJUgI
MISTAKE.03 — NO ITERATIONANALYSIS
03 / THE SKILL

Kill the first pass. The first output is a draft, not a deliverable.

THE MISTAKE
Shipping the first pass.

THE MISTAKENO REVISION
No second prompt. The first output ships as final — no critique, no revision.
THE DIRECTION
+ KILL RULEIf the first pass looks like a template, kill it.
+ CRITIQUEBrief me on what you’d change before rendering again.
+ REVISIONRevision: Kill the gradient. Lead with the headline. One CTA.
THE COST —The first pass is the model’s habit, not your answer. Shipping it is letting the tool direct you.
PRINCIPLE 04 — BUILD TO LEARN. BELIEVE WHAT YOU LEARN.
REF — ANTHROPIC · THE PROMPTING PLAYBOOK: generate, evaluate, repair. The first pass is never the answer. https://youtu.be/G2B0YWuJUgI
