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

Specify the concrete criteria of expert work \(e.g., 'ensure O\(n log n\) complexity, use type hints, handle nulls'\) instead of assigning a persona.

Journey Context:
Persona prompts were useful for style transfer in early models, but for coding, they often bias the model toward verbose, boilerplate-heavy 'tutorial-style' code rather than production-grade code. Modern RLHF models are already tuned for maximum capability; persona prompts waste tokens on style mimicry and can trigger sycophancy or outdated patterns associated with the persona in the training data. Concrete constraints bound the output space effectively.
