What it does
Ads often claim more than the proof supports. Sometimes the claim is plain ("lose 5 pounds"). Often it is only implied. A "clean feel" can sound like "safe", and "doctor-loved" can sound like "approved". This prompt reads your copy as a doubter would. It lists the claims and the ones the copy only suggests, pairs each with the proof you pasted, and notes how close the proof sits. A claim is matched only when the proof is there, near, and the implied meaning is true. For each gap you get one of three fixes: make the claim smaller, move real proof next to it, or add proof you hold. It never writes a new fact.
