[counterintuitive] Using elaborate persona prompts \('Act as a world-class senior developer'\) to improve code quality

Drop persona fluff and provide concrete evaluation criteria, style guides, and specific constraints directly.

Journey Context:
Early models benefited from persona prompts because they shifted token distribution towards formal/professional language. Modern models are heavily RLHF'd for helpfulness and code quality; adding personas often introduces narrative fluff, increases latency, and can paradoxically constrain the model to stereotypical 'expert' behaviors \(e.g., boilerplate-heavy patterns, verbose explanations\) rather than optimal, idiomatic code. The model's baseline capability is higher than the persona's ceiling.
