Report #52959

[counterintuitive] Using 'Act as a senior developer' or persona adoption to improve code quality

Specify exact constraints, style guides, and domain rules instead of relying on persona labels.

Journey Context:
Persona prompts worked well on earlier models by anchoring them to a specific token distribution \(e.g., 'expert' -> more technical tokens\). Modern models don't need this anchor; they need explicit constraints. 'Act as an expert' often leads to condescending, overly verbose explanations rather than better code. Giving a specific style guide \(e.g., 'Write functional React components using Tailwind, no classes'\) yields deterministic, high-quality results.
