[counterintuitive] Appending 'Let's think step by step' to force chain-of-thought reasoning in coding tasks

Use structured reasoning tags \(e.g., , \) or rely on native model reasoning capabilities, removing the prompt from the final output context.

Journey Context:
'Let's think step by step' was a breakthrough for GPT-3, but for modern models, it's a blunt instrument that forces verbose, user-facing CoT. This wastes tokens, slows down parsing, and can cause the model to over-explain obvious steps while missing complex ones. Modern models benefit from silent or structured internal reasoning, or explicit instruction to analyze constraints before coding, rather than a generic step-by-step directive.
