[counterintuitive] Using 'Act as an expert' role-playing prompts to improve code quality

Specify concrete constraints, standards, and evaluation rubrics instead of persona titles.

Journey Context:
Persona prompts were popular in 2023 to activate domain-specific weights. However, modern RLHF models are already trained to be helpful experts; saying 'act as an expert' often triggers sycophancy or verbose, stylistic prose rather than deeper reasoning. Specifying constraints \(e.g., 'optimize for time complexity O\(N\)', 'adhere to PEP8', 'write tests using pytest'\) directly targets the model's instruction-following capabilities and avoids the 'expert' persona trap where the model sounds confident but is wrong.
