Makes the tool show its workings so you know what to verify.

Review the answer you just gave me as if you were a sceptical colleague. List: every factual claim in it that I should verify before relying on it, and where I could verify each one; any assumptions you made that I did not state; anything you are less confident about, and why; and what a person with the opposite view would say. Do not soften the critique to be agreeable, and do not change your original answer while doing this.

Safe use: Works in the same chat, straight after any answer. It reduces the risk of confident nonsense; it does not remove it. Important facts still need a human check.
