Your first prompt: describe, don't dictate

The most common beginner mistake is writing prompts like code: "add a div with a flexbox row of three buttons". You are hiring the agent for its implementation skill — describe the outcome instead: "a pricing section with three plans, the middle one highlighted". A strong first prompt covers three things: who the app is for, what they need to do in it, and how it should feel. One paragraph each. Concrete beats clever: "a booking page for a hair salon where clients pick a service, a stylist and a time slot" gives the agent everything it needs. Write your real first prompt now, for a small tool you actually want. Resist the urge to list twenty features — version one needs exactly one job done well.
