[counterintuitive] Using 'Let's think step by step' to force complex reasoning

Rely on native reasoning models \(o1/o3\) or enforce structured reasoning traces with explicit scratchpad tags \(e.g., \) and tool-augmented ReAct loops.

Journey Context:
The zero-shot CoT phrase was a breakthrough for GPT-3, but modern instruction-tuned models are over-trained on it, leading to verbose, shallow rambling rather than deep logic. Frontier models now either handle CoT internally via hidden reasoning tokens or require structured, tool-augmented reasoning. Forcing visible CoT with a magic phrase on standard models degrades performance, increases latency, and often results in post-hoc rationalization rather than genuine deduction.
