[counterintuitive] Using 'Let's think step by step' as the primary Chain of Thought trigger

Use structured reasoning tags \(e.g., , \) or rely on native reasoning models \(o1\) and tool-use for computation instead of zero-shot CoT triggers.

Journey Context:
Let's think step by step was a breakthrough in 2022 for zero-shot CoT, but modern models over-rely on it, producing verbose, unfocused rambling rather than targeted logic. It is a blunt instrument that activates shallow sequential token generation. Modern models respond better to structural constraints \(e.g., First outline the approach in tags, then write the code\) or native reasoning modes that separate computation from output.
