Ask ‘what would make this answer wrong?’

Works with ChatGPT · Claude · Gemini

What you’ll be able to do

Stress-test an answer by asking how it could be wrong.

The problem

A single confident answer hides the conditions under which it fails.

What this skill does

Asking how it could be wrong surfaces hidden assumptions and edge cases.

When to use it

  • Use before relying on an important answer.

Take this answer — [answer] — and stress-test it: list the assumptions it depends on, the conditions under which it would be wrong, and the edge cases it doesn't handle. Then give a more cautious version.

Why this works

Asking how an answer fails reveals the assumptions you'd otherwise discover the hard way.
