[counterintuitive] Using 'Act as an expert' role-playing prompts to boost coding performance

Drop the persona fluff. Specify exact constraints, tech stack versions, and architectural patterns directly.

Journey Context:
In 2023, 'Act as a senior developer' was thought to prime the model for better code. In reality, modern models don't gain reasoning ability from role-play; it just consumes tokens and can bias the model toward stereotypical but suboptimal patterns. Explicit constraints \(e.g., 'Use Python 3.12, prefer composition over inheritance'\) directly govern the output distribution.
