[counterintuitive] Adding more reasoning steps and ReAct loops always improves agent accuracy

Use direct prompting for simple extraction or formatting tasks. Reserve multi-step reasoning \(ReAct/CoT\) for tasks requiring composition, math, or logical deduction.

Journey Context:
The prevailing wisdom is that CoT and multi-step tool-calling \(ReAct\) are universally superior. In reality, for simple tasks, forcing an agent to 'think step-by-step' introduces latency and increases the surface area for hallucination or error cascades \(where an early reasoning mistake corrupts all subsequent steps\). Direct prompting is faster, cheaper, and often more accurate for straightforward mappings.
