Report #96762

[counterintuitive] Prefixing prompts with "Act as a senior software engineer" or "You are an expert in Python"

Specify the exact context, constraints, and standards of the domain rather than assigning a persona.

Journey Context:
Persona prompts worked early on to nudge model weights into a specific token distribution. Now, they often backfire by introducing sycophancy \(the model acting "expert-like" but making confident mistakes\) or are ignored entirely. Modern models respond better to explicit constraints: "Ensure the code adheres to PEP8 and uses type hints" rather than "Act as a PEP8 expert". The model's performance is bounded by the clarity of the rules, not the flavor of the role.
