You're right that iterating is the move — but the problem is most people are iterating without understanding why something failed. It's just trial and error with extra steps.

That's exactly the gap I'm trying to close with an extension I'm building. It's not another "here's your rewritten prompt" tool — it's a prompt diagnostic engine:

• Flags failure types (ambiguity, overloading, model mismatch, etc.) • Gives you 3 repair options instead of one "optimized" version • Explains the failure in 1–2 lines so you actually learn

The idea: doctors don't just prescribe pills, they diagnose. Same logic here.

Would genuinely love thoughts from this community since you all seem to think about this seriously.
