[counterintuitive] Using elaborate persona prompts like 'Act as a world-class senior developer' to improve code quality

Specify concrete context, constraints, and standards \(e.g., 'Adhere to PEP 8, optimize for readability, use Python 3.12 type hints'\) instead of personas.

Journey Context:
Early models needed persona framing to escape default bland behaviors. Modern models already possess strong baseline coding capabilities. Persona prompts waste tokens, dilute instructions with sycophancy, and often backfire: the model adopts a verbose, explanatory 'expert' tone instead of just outputting concise, high-quality code. Direct, constraint-based instructions yield better adherence than role-playing.
