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

Specify exact constraints, tech stack versions, and evaluation rubrics instead of relying on persona assignment.

Journey Context:
Persona prompting worked early on to activate latent capabilities in base or early instruct models. Now, it wastes context window and can backfire by making the model overly verbose or pedantic, ignoring actual constraints in favor of 'expert' style. Modern instruction-tuned models respond better to clear evaluation metrics and strict constraints than flattery or role-playing.
