[counterintuitive] Using 'Act as an expert senior developer' to boost coding performance

Drop role-play fluff; use the context window for specific constraints, tech stack versions, and explicit architectural boundaries.

Journey Context:
In 2023, 'act as an expert' seemed to nudge base models into better formatting. For modern instruction-tuned models, it wastes tokens and can cause the model to adopt a pedantic, explanatory tone rather than just writing concise code. Specificity and constraints are the real levers for performance.
