[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 \(o1/o3\) where CoT is internalized, rather than forcing verbose textual CoT.

Journey Context:
"Let's think step by step" was a breakthrough in 2022 for zero-shot CoT, but modern models over-index on it, producing verbose, unfocused rambling that degrades task performance. It is a blunt instrument that forces linear, often redundant, reasoning. Modern instruction-tuned models respond better to explicit structural constraints \(e.g., "First, outline dependencies. Then, write code."\) or dedicated reasoning tokens that separate computation from the final output.
