[agent\_craft] Chain-of-thought reasoning inflates tokens and latency without helping accuracy
Ask for step-by-step reasoning only on multi-step, ambiguous, or tool-planning tasks. Skip CoT for deterministic formatting, simple lookups, or single-file edits. Use targeted prompts like think step by step before choosing tools.
Journey Context:
CoT improves arithmetic, symbolic, and commonsense reasoning in large models, but it is not free. Verbose reasoning increases latency and can introduce spurious steps. The common mistake is adding explain your reasoning to every request. The correct pattern is to gate CoT: use it when the answer depends on sequential decisions or when tool selection is non-obvious, and omit it when the task is a direct transformation.
