[agent\_craft] Chain-of-Thought latency overhead on simple code transformations

Disable Chain-of-Thought \(remove 'Let's think step by step' or equivalent\) for deterministic code transformations \(regex, format conversion, simple mapping\). Use zero-shot direct generation with a low max\_tokens limit. Only enable CoT explicitly when the task involves debugging, multi-step logic, or requires explanation.

Journey Context:
While CoT improves accuracy on complex reasoning \(Wei et al.\), it increases token generation latency by 3-5x and cost proportionally. Developers often apply CoT universally to coding agents, but for simple transformations \(e.g., 'convert this JSON to CSV'\), CoT adds no accuracy benefit while significantly slowing response time. The pattern is to use a classifier or heuristic to route simple tasks to direct generation and complex tasks to CoT, or to dynamically append the CoT trigger only when uncertainty is detected.
