[counterintuitive] Using 'Act as an expert \[role\]' to improve domain accuracy

Specify the exact evaluation criteria, constraints, or domain-specific rubrics the model should apply, rather than assigning a persona.

Journey Context:
Persona prompting was popular to set context, but 'Act as an expert' doesn't inject missing knowledge; it mostly shifts tone to sound more confident, which increases hallucination risk. Modern models are already trained on expert data. To get expert-level outputs, define the \*rules\* an expert follows \(e.g., 'Evaluate this code for race conditions and memory leaks'\) rather than asking it to play a role.
