[agent\_craft] Asking the model to 'think step by step' slows answers and can reduce accuracy on simple tasks
Reserve explicit chain-of-thought for multi-step math, logic, debugging, and planning. For retrieval, transformation, or recall tasks, give direct instructions and request only the final output. If transparency is needed, ask for a short rationale after the answer.
Journey Context:
Chain-of-thought is not free: it increases token spend and latency and can cause the model to overthink a simple question, introducing errors that a direct answer would avoid. Wei et al. showed CoT unlocks reasoning on complex tasks, but the gains are highly task-dependent. In coding agents, we saw CoT improve bug diagnosis but degrade simple refactors where the model started inventing constraints. Self-consistency voting raises accuracy further but multiplies cost; reserve it for high-stakes decisions.
