Report #38208

[counterintuitive] Prefixing prompts with 'Act as a senior software engineer' significantly improves code quality

Drop the role-play and specify exact constraints, tech stack versions, and evaluation criteria \(e.g., 'Use Python 3.11, asyncio, ensure no blocking I/O. Validate with Pydantic'\).

Journey Context:
Role-playing worked early on to nudge the model's weight space into technical domains. Now, models are already highly tuned for coding. 'Act as an expert' wastes context window and can introduce bias \(e.g., an 'expert' might write overly complex, clever code instead of simple, maintainable code\). Concrete constraints yield deterministic, high-quality outputs better than persona adoption.
