Report #24349

[counterintuitive] Using 'Act as a senior developer' or 'You are an expert' to improve code quality

Specify the exact standard, library version, or constraints \(e.g., 'Write Python 3.12 code using type hints and conforming to PEP 8'\) instead of persona-based role-playing.

Journey Context:
Modern instruction-tuned models are optimized to follow directions, not role-play. Persona prompts add tokens without adding constraints, often resulting in sycophantic or verbose outputs. Specifying exact standards \(PEP 8, ESLint rules, specific library versions\) gives the model concrete boundaries to operate within, which reliably improves output quality over vague 'expert' framing. The shift from 'system' to 'developer' messages in APIs reflects this: instructions beat personas.
