The Core Laws
Ask for the holes, not the applause
The machine agrees with whoever is steering. Prompt it to argue, and treat easy agreement as a warning.
The machine takes your framing as a gift. Present a plan with pride and it finds the plan excellent; steer even slightly and it agrees; ask whether this isn't right and it is. Agreement is the path of least resistance through its training, which makes unearned agreement its default product. The more polished your idea sounds, the less resistance it will meet.
Flip the request. Ask what breaks this, what a skeptic would say, or, in one operator's words, “Why is this not a done deal?” The same engine that flatters fluently critiques fluently; it just needs to be pointed at the target. And watch your own thumb on the scale: if you argued it into agreeing, you haven't passed review, you've defeated the reviewer. Easy agreement is a warning light, not a grade.
How to practice it
Prompt the prosecution.
Ask for the failure modes, the hard questions, the case against, explicitly. It will not volunteer them against your visible enthusiasm.
Separate author from judge.
Have the critique come from a fresh session, or a framing with no stake: present it as a plan someone sent you, and ask what's wrong with it.
Treat easy agreement as alarm.
If the review found nothing, the review didn't happen. Re-ask with teeth.
Watch your own steering.
Notice when you've pushed back twice and it folded twice. You may be rubber-stamping yourself through a machine.
