Claude Sonnet/Opus 5.5 Standard-Setting Prompt Template

7 sections you paste above any task. They set the standard instead of describing the work. Best one: if Sonnet can't crack a hard problem after a second attempt, it tells you to hand it to Opus, with the goal, the evidence and everything it already tried. Rules it holds: → a request for ideas is not a request to build → two attempts with no progress means change approach, not try again → a progress update is not a deliverable → once the checks pass, stop Fill in the 3 lines at the top and it works on anything.
