[counterintuitive] Assigning expert personas like 'Act as a senior developer' to improve code quality

Replace persona assignments with explicit context, constraints, and evaluation criteria. Define \*what\* the expert would do, not \*who\* the model is.

Journey Context:
Role-playing prompts were popular when models needed high-entropy activation to break out of generic assistant modes. Now, they often backfire by introducing stereotypical behavior \(e.g., 'senior developer' might produce overly verbose, pedantic code or use outdated idioms associated with the persona's 'age'\). Modern models respond much better to direct constraints \(e.g., 'Write Python code that maximizes for readability and uses type hints'\) than identity role-play, which wastes tokens and injects unpredictable stylistic bias.
