[agent\_craft] Adding 'Let's think step by step' increases token cost without improving code correctness for simple API calls

Use CoT prompting only when the task requires multi-step reasoning \(debugging, algorithm design\); omit for straightforward generation tasks like 'write a React component that...'

Journey Context:
While Kojima et al. showed CoT improves reasoning, it adds latency and cost. For code generation where the pattern is memorized \(common React patterns\), CoT causes the model to over-explain standard boilerplate, wasting tokens without quality gains.
