[agent\_craft] Adding 'think step by step' slows responses without helping

Use zero-shot CoT only for arithmetic, logic, multi-hop retrieval, or conflict resolution. Disable it for classification, simple extraction, or deterministic formatting tasks.

Journey Context:
Kojima et al. showed that 'Let's think step by step' unlocks reasoning, but the benefit is task-dependent. On simple classification it adds tokens and can increase overconfident confabulation. The right heuristic is: if a human would need scratch paper, use CoT; if the answer is a lookup or format transformation, skip it. Many agents enable CoT globally and pay the latency cost for no gain.
