[agent\_craft] Chain-of-thought degrades performance on simple code refactor tasks

Reserve explicit chain-of-thought for tasks that require multi-step planning, arithmetic, or novel reasoning. For straightforward local refactors, give direct instructions with clear acceptance criteria and skip the reasoning preamble.

Journey Context:
CoT helps when the answer requires intermediate reasoning steps, but it hurts on tasks where the answer is mostly pattern-matching or already implicit in the model's prior. Forcing narration increases token cost and can introduce confabulated justifications that diverge from the intended one-line change. The right call is to match cognitive load to technique: CoT for hard planning, direct execution for obvious edits.
