[agent\_craft] Agent wastes tokens and increases latency by emitting chain-of-thought for deterministic code transformations

Disable explicit CoT \(omit 'Let me think step by step'\) for deterministic transformations; use direct generation with constrained JSON mode or regex stop sequences

Journey Context:
Chain-of-thought significantly improves reasoning on math and logic puzzles, but for deterministic code refactoring \(e.g., converting snake\_case to camelCase or adding type hints\), CoT adds ~30-50% token overhead with zero quality gain and introduces risk of hallucinated reasoning steps that contradict the actual code. The fix is to use zero-shot with strong system instructions and structured output constraints; reserve CoT only for tasks with explicit multi-hop reasoning requirements \(debugging unknown errors, design trade-off analysis\).
