[agent\_craft] Agent wasting tokens and time on chain-of-thought reasoning for simple lookup tasks

Disable chain-of-thought \(direct tool calling\) for retrieval/read-only operations; enable CoT only for debugging, planning, or multi-step modification tasks where hypothesis generation reduces error rates.

Journey Context:
Chain-of-Thought \(CoT\) increases accuracy on complex reasoning tasks but adds significant latency and token cost. For agents, applying CoT universally hurts performance: if the task is 'fetch the user record', reasoning 'I need to look up the user in the database using the get\_user tool' adds no value and doubles the response time. However, for debugging \('why is the test failing?'\), CoT allows the agent to form hypotheses before checking files, reducing redundant tool calls. The ReAct paper implicitly uses this dichotomy \(reasoning for acting\), but modern agent design should explicitly gate CoT on task complexity.
