[counterintuitive] Using 'Let's think step by step' to force reasoning in coding tasks

Use native reasoning models \(o1, o3-mini\) for complex logic, or explicitly request a structured plan \(e.g., 'First, outline the module structure, then write the code'\) rather than relying on the magic phrase.

Journey Context:
'Let's think step by step' was a breakthrough for GPT-3 era models to elicit chain-of-thought. For modern coding models, it often results in verbose, unfocused rambling that consumes context window without improving accuracy. If deep reasoning is needed, dedicated reasoning models handle this internally and more effectively. If step-by-step planning is needed, explicitly define the steps or ask for a design doc first.
