Report #76949
[counterintuitive] Prefixing prompts with 'Act as a senior developer' to improve code quality
Drop persona roles and directly specify the technical constraints, tech stack versions, and coding standards.
Journey Context:
Persona prompting was useful for early base models to steer them into specific data distributions \(e.g., 'act as a Python expert' made Python code more likely\). Modern RLHF models are already aligned to be highly capable experts. Adding 'act as an expert' provides zero technical information and often backfires by inducing verbose, condescending, or cliched 'expert' language instead of concise, correct code. Direct constraints \(e.g., 'Use Python 3.12, type hints, and Pydantic v2'\) yield deterministic control over the output distribution.
