I mean, it's his plans, so of course he'd recognize if AI is hallucinating. For what is worth I have two different skills in claude code which are two reviewers with two distinct personalities. At every plan I write, I have them review it and find edge cases, critique. I don't think I've seen hallucinations since few opus versions at least. Feedback is useful 4 times out of 5. Very useful actually. And one time is not very valuable or wrong (but it requires the two different skills to agree).
