[counterintuitive] Role-playing prompts like 'Act as a senior software engineer' significantly improve code generation quality

Replace persona assignments with explicit architectural constraints, tech stack definitions, and style guidelines.

Journey Context:
In 2023, 'Act as an X' was a popular trick to steer the model's output distribution towards expert domains. However, modern models are already trained on vast amounts of expert code. Simply telling a model to be an 'expert' adds no new information and wastes tokens. Worse, it can trigger cliched or overly verbose 'expert-like' prose rather than better code. What actually works is defining the boundaries of the expertise \(e.g., 'Use React Server Components, strictly type all props'\).
