[counterintuitive] Using elaborate persona prompts like 'Act as a senior developer' to improve code generation

Drop persona flattery and provide concrete evaluation criteria, style guides, or specific constraints directly.

Journey Context:
Early models responded well to persona activation because it shifted the latent space into a specialized vocabulary. Modern models are already trained on expert data; telling them to 'be an expert' adds token cost and can backfire by making the model overly verbose or pedantic, mimicking the stereotype of an expert rather than executing the task expertly. What actually works is defining the rules of the expert \(e.g., 'Prefer standard library, avoid deprecated APIs, use type hints'\).
