Report #55868

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

Specify concrete constraints, style guides, and evaluation rubrics instead of vague persona adjectives.

Journey Context:
Persona prompting helped activate latent capabilities in base models, but in modern RLHF-tuned models, 'expert' is a weak prior that often induces sycophancy—the model assumes the user is right and fails to correct bad premises. Specifying 'Follow PEP8, use type hints, prefer immutability' directly targets the model's attention on the exact token distributions that represent high-quality code, bypassing the sycophancy trap.
