Report #91896

[counterintuitive] Prefixing prompts with 'Act as a senior developer' or 'You are an expert in Python' to improve code quality

Drop persona fluff. Instead, specify the exact constraints, style guides, and domain knowledge required \(e.g., 'Write Python 3.11 code using type hints and following PEP 8'\).

Journey Context:
Early models benefited slightly from persona framing because it shifted the probability distribution toward formal language. Modern models are highly instruction-tuned; 'Act as an expert' just adds token overhead and can trigger sycophancy \(the model acting confident but wrong\). Specific constraints and context directly condition the model's output space, whereas personas only condition tone.
