[agent\_craft] Agent generates verbose chain-of-thought for trivial file reads, wasting tokens and latency

Reserve explicit or step-by-step reasoning tags only for multi-step logic, debugging, or ambiguous requirements; use direct tool calls for deterministic single-step operations like read, grep, or ls.

Journey Context:
Research shows CoT improves accuracy on arithmetic, symbolic reasoning, and debugging by 15-40%, but adds ~2-3x token overhead and latency due to forced 'Thought' generation. For agents that just need to read a file or run grep, forcing a 'Thought' step creates noise and slows response. The correct heuristic is: if the plan is obvious from the user query \(read X, then write Y\), skip CoT and use direct sequential calls; if the path requires exploration \(debug this error\), use CoT to observe and reason iteratively. This prevents 'reasoning pollution' where the model overthinks simple operations.
