Give Any AI Model a Verify Loop Before It Answers

Somewhere in the last year, an Executive reading this sent an AI-drafted board summary, contract clause, or financial projection straight through without a second look, because the first paragraph read clean and confident. Then someone on the other end caught the error. Maybe it was a misread clause, a stat that did not match the source document, or a plan that ignored a constraint mentioned two messages earlier. The output looked finished. It was not checked.

That gap between "looks done" and "is correct" is where high-stakes AI work actually fails. A model asked a complex question tends to produce its first coherent line of reasoning and run with it, the same way a person under time pressure grabs the first plausible answer instead of the best one. For a one-line lookup that is fine. For a pricing model, a client-facing memo, or a legal summary, that first draft is exactly the answer that should not go out unexamined.

What follows is a single block of text, roughly 60 words, that changes how a model approaches a hard question before it writes a single sentence of the answer. It costs nothing, works in ChatGPT, Claude, Gemini, or Copilot, and takes less time to add than it took to read this paragraph.

The Instruction That Forces a Plan Before an Answer

Paste this at the top of any complex prompt, before the actual question or task. It works in any chat interface, free or paid, because it is plain instruction text, not a special mode or setting.

Before you answer, work through four steps silently: comprehend what I actually need and note any ambiguity, sketch two possible approaches and pick the stronger one, execute carefully and show your work where it matters, then check your own answer against my original request before you reply. Give me the final answer, plus a short list of what you verified and what I should still check myself.
