Report #77664

[counterintuitive] Using persona prompts like 'Act as a world-class senior developer' to improve code quality

Specify the exact constraints, tech stack, and evaluation criteria \(e.g., 'Write Go code that prioritizes readability and avoids goroutine leaks'\) instead of relying on persona.

Journey Context:
Persona prompts worked slightly in earlier models by shifting token distribution toward professional jargon, but modern models don't get 'smarter' by being told they are experts; they just adopt a tone. Worse, 'senior developer' might bias the model toward overly complex, clever-but-unmaintainable code. Specificity directly conditions the output distribution, whereas personas introduce unpredictable stylistic variance.
