Report #24175

[counterintuitive] Using 'Act as an expert senior developer' to boost model performance

Drop the persona and specify the exact constraints, style, and standards of the target domain instead.

Journey Context:
Early models sometimes responded to persona prompts by aligning their token distribution with expert-sounding language. Modern models already have strong priors for expert coding patterns; 'act as an expert' just wastes tokens and can cause sycophancy or overly verbose, jargon-heavy outputs. Specifying 'use Python 3.12, follow PEP8, prefer standard library, add type hints' directly conditions the output distribution on the actual features you want.
