[counterintuitive] Prefixing prompts with 'Act as a senior software engineer' to improve code quality

Specify the exact domain constraints, standards, and context rather than assigning a persona.

Journey Context:
Persona prompting was a hack to bias the model's token distribution towards professional jargon. Modern models already have strong priors for expert knowledge; adding personas often leads to sycophancy or verbose role-play \('Ah, my friend, as an expert...'\) that wastes tokens and degrades instruction following. Context and constraints \(e.g., 'Ensure the code adheres to OWASP top 10'\) directly steer the output distribution without the theatrical overhead.
