[counterintuitive] Using 'Act as a world-class expert' to improve output quality

Specify exact criteria and constraints of the task rather than assigning a persona.

Journey Context:
Role-playing was a hack to weight the model's prior towards high-quality text. Modern models don't need ego-stroking; they need constraints. 'Act as an expert' often triggers sycophancy or overly verbose, jargon-heavy explanations instead of precise, correct answers. Specifying the exact standard \(e.g., 'Write code adhering to OWASP ASVS'\) provides measurable constraints that the model can actually follow, whereas 'expert' is ambiguous and often degrades performance on objective tasks.
