Double-check

Force it to re-read its own answer from scratch.

Are you sure? Re-check your previous answer from scratch. Verify the key facts, calculations, assumptions, sources, and interpretation of my request. Confirm you followed every instruction and constraint, and identify any errors, omissions, unsupported claims, or better-supported conclusions. Do not anchor on your prior answer. Correct anything that needs correcting; otherwise, confirm that the original answer still holds.
