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

Drop persona flattery; specify the exact constraints, standards, and evaluation criteria of the domain \(e.g., 'Ensure code is thread-safe, uses O\(n log n\) algorithms, and passes PEP 8 linting'\).

Journey Context:
Early base models benefited from persona prompting because it shifted the probability distribution into domain-specific token space. Modern RLHF'd models are already tuned for high-quality assistance; 'Act as an expert' wastes tokens and often induces sycophancy \(the model acting like an expert by being overly confident in wrong answers\). Specifying concrete constraints forces the model to apply actual expert-level heuristics rather than just adopting an expert tone.
