Prompt Engineering Fundamentals
Last reviewed
Correct answer: B. Treat it as a draft and revise the prompt against the gap shown
Explanation
The principle — A disappointing response is diagnostic information. It tells you which part of the specification was missing or ambiguous, which is knowledge you did not have before you sent it.
Why the key is correct — Google describes prompt design as a test-driven, iterative process, and says it can require a few iterations before you consistently get the response you are looking for. Revising against the observed gap is what makes each round cheaper than the last.
Why the others are wrong — Rewriting from scratch discards the evidence. Resending unchanged relies on luck. Hand-editing fixes the output while leaving the prompt to fail again.
Remember this — Read the bad answer for what it reveals about your prompt, then change that.
