If you give an AI a vague idea and tell it to build an app, it will build it. It will probably look nice. And it will probably fail, because you didn’t think through the edge cases.
Before you build anything, force the model to interrogate your idea.
The Prompt
I want you to build this rough idea. Do not build anything yet. Interview me like Mark Zuckerberg or Sam Altman or Brian Chesky, experts at building companies that get PMF. One question at a time, 15 questions max, hunting for the thing I haven’t thought about. Push back when my answers are vague. After the interview, write the full spec and list three ways this fails. Then build the V1.
[Attach your rough idea]
Why this works
You are using the model as a sparring partner, not just a code generator. By forcing it to ask one question at a time, you prevent it from giving you a generic checklist. It has to react to your specific answers and dig deeper into the weak points of your logic.
