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

Specify the exact constraints and standards of the domain \(e.g., 'Write code adhering to SOLID principles with edge-case tests'\) rather than assigning a persona.

Journey Context:
Early models benefited from persona prompts because it shifted the latent space towards professional jargon. Modern models default to high-quality outputs. 'Act as an expert' wastes tokens and paradoxically increases sycophancy—the model becomes overly confident in its mistakes or writes overly complex 'clever' code instead of simple, maintainable code. Contextual constraints yield deterministic improvements; personas yield stochastic style changes.
