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

Specify the exact evaluation rubric, methodology, or constraints the expert would use, rather than just assigning the role.

Journey Context:
Persona adoption changes tone but not underlying capability. Models often mimic the verbose style of an expert without the rigor. Specifying a process \(e.g., 'Evaluate this code against the OWASP top 10, listing each vulnerability found'\) forces the model into a specific cognitive pathway, yielding higher signal than a generic 'Act as a senior security engineer.'
