[counterintuitive] Adding 'let's think step by step' reliably improves reasoning

Replace generic Chain-of-Thought triggers with structured, domain-specific reasoning templates \(e.g., '1. Identify constraints 2. Draft logic 3. Verify against constraints'\).

Journey Context:
In 2022, 'let's think step by step' \(Zero-Shot CoT\) was a breakthrough because it unlocked hidden reasoning in base models. Today, instruction-tuned models are heavily trained on CoT data. A generic 'step by step' prompt now often triggers boilerplate rambling or verbose, unfocused computation. It is a blunt instrument that wastes tokens and can lead to hallucinated intermediate steps. Modern models require structured reasoning directives that constrain the search space, forcing the model to compute along the correct path rather than just computing more.
