Option A directly addresses the tone problem by specifying both the required voice and the audience for whom the response is being written. Audience context helps Claude determine vocabulary, technical depth, formality, and emphasis. Option B addresses ambiguity by providing a concrete example that demonstrates the desired structure, detail level, tone, and overall quality.

Option C may produce superficial variation, but it does not correct the prompt’s underlying deficiencies. Option D supplies no actionable description of what must improve. Option E increases output variability without clarifying the missing tone or detail requirements and may make results less consistent.

Prompt iteration should be diagnostic. The user should identify the specific defect, modify one or more prompt elements that control that defect, generate a new output, and compare it with the original success criteria. If the response remains too general, the next revision might add required sections, source material, minimum depth, or an evaluation rubric.

Anthropic’s prompting guidance recommends clear instructions, relevant context, examples, and explicit output requirements. Examples are particularly useful when the intended standard is difficult to describe abstractly. A and B therefore introduce information Claude can act upon, while the other choices merely repeat or randomize the same insufficient instruction. Anthropic’s prompt-engineering guidance
