[agent\_craft] Chain-of-thought makes coding agents slower without improving accuracy

Use explicit chain-of-thought only for multi-step planning, debugging, or ambiguous requirements. For single-file edits with clear specs, generate code directly. When CoT is needed, isolate it in a scratchpad field or reasoning tool; never mix it with tool arguments or final output.

Journey Context:
Agents often prepend 'think step by step' to every request, but the original CoT gains were on math and commonsense tasks that require decomposition, not routine code completion. CoT burns tokens, adds latency, and risks reasoning contamination where the model explains instead of executing. The rule of thumb: if the task is 'do X given these exact specs', skip CoT; if it is 'figure out why this fails' or 'choose between several architectures', use CoT.
