[counterintuitive] Use 'Let's think step by step' for complex reasoning tasks

Use structured reasoning frameworks with specific delimiters \(e.g., \) or dedicated reasoning models \(o1\) that handle computation internally, rather than zero-shot CoT triggers.

Journey Context:
'Let's think step by step' was a breakthrough in 2022 for zero-shot CoT, but it is now a blunt instrument. It often leads to verbose, unfocused rambling that consumes output tokens without improving accuracy. Modern approaches either use structured tags to separate reasoning from the final answer \(allowing programmatic stripping\) or rely on models trained to reason natively \(like o1\) which do not need explicit CoT triggers.
