Report #26985

[counterintuitive] Using 'Act as an expert' role-playing prompts

Specify the context and constraints of the task \(e.g., 'Target Python 3.11, use asyncio, follow PEP 8'\) rather than assigning a persona.

Journey Context:
Early models sometimes responded to persona prompts by adopting a tone that mimicked expertise. Modern models don't gain domain knowledge from role-play; they just adopt the style \(often verbose, condescending, or overly cautious\). Persona prompts can backfire by making the model say 'As an expert, I must warn you...' instead of just doing the task. Contextual constraints directly steer the output distribution.
