[counterintuitive] Using 'Act as an expert' persona prompts to improve code quality

Specify concrete evaluation criteria and constraints instead of assigning a persona.

Journey Context:
Persona prompting worked on early instruct models to activate latent capabilities, but modern RLHF models already operate at their max capability ceiling. 'Act as an expert' wastes tokens and triggers sycophancy—the model mimics the tone of an expert rather than doing expert-level work. Specifying constraints \(e.g., 'use type hints, handle edge case X, minimize cyclomatic complexity'\) forces the actual expert behavior.
