The PRD Prompt That Audits Itself For Hallucinations and Failure Modes
In my work as a PM, I’ve written enough PRDs to know this:
if they’re too long, nobody reads them
f they’re too vague, nobody respects them
So I took everything I learned about product management discipline - clarity, brevity, testability - and combined it with everything I’ve learned about vibecoding and spec-driven development.
The PRD Builder is at version 16, shaped by 15 rounds of sharpening while building stackshelf.app
There are plenty of paid tools out there that promise to generate a PRD for you, but this prompt gives you the same clarity and structure, without the price tag.
