A municipal snow-plow router prompt includes context, instruction, a street list, constraints, and a table format, but no persona. The draft reads like a press release. Which missing component most likely caused the perspective drift?
Select an answer to reveal the explanation.
Short Explanation
When every structural piece is present except who should speak, the model improvises a voice — here, a press release. Role is the missing casting call. The street list and table format were already there; persona was not.
Full Explanation
Role contributes persona, tone, and testing responsibilities. With context, instruction, input, constraints, and output format present but role absent, replies can drift into non-tester styles. The snow-plow scenario shows that structure alone does not fix perspective without an explicit tester persona.
