A customer success manager wants Claude to draft replies to complaints in the company's voice. Her prompt describes the voice as "warm but professional, not too casual, empathetic yet efficient." The drafts are fine but don't sound like her team. What is the most effective addition to the prompt?

Answer: A — Two or three replies the team rates highly, noting to match their tone and structure but not their content.

Concrete examples convey a voice far more precisely than descriptions, so (a) is the most effective addition; saying what to copy (tone and structure, not content) prevents the samples being reused verbatim. (b) adds more words of the same vague kind. (c) relies on self-assessment, which doesn't change how the drafts are written and isn't reliable evidence. (d) gives up on the goal and pushes all the work back to the team.
