[counterintuitive] Using elaborate role-playing prompts \('Act as a world-class senior developer'\) to boost coding performance

Provide concrete evaluation criteria, style guides, and specific constraints instead of persona adjectives.

Journey Context:
Persona prompting helped early models stay in distribution, 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' code instead of simple, maintainable code. Specificity and constraints replace persona.
