how to use theseEach prompt opens on its own page with a fill-in bar for the blanks and a copy button. Paste the result into a fresh chat, then treat the model like a sparring partner: push back, ask for the harder follow-up, and make it grade you. The prompts are written so the model asks one question at a time and never reveals a full answer unless you ask.
