[agent\_craft] ReAct reasoning loops add unnecessary latency and token cost for deterministic single-tool calls

Skip the ReAct \(Thought -> Action -> Observation\) loop for deterministic, idempotent, single-step tools \(e.g., read\_file, get\_current\_time\). Use direct tool invocation with immediate return. Reserve ReAct for multi-step planning, dependency chains, or when the tool failure requires strategy revision.

Journey Context:
ReAct \(Reasoning \+ Acting\) is powerful for complex multi-hop tasks, but agents often apply it universally, even for simple file reads. This adds 2-3x token overhead and latency for zero benefit. Research shows ReAct improves accuracy on multi-step QA but degrades performance on single-step API calls by introducing unnecessary reasoning overhead. The fix is to branch: if the tool is deterministic and failure is cheap \(idempotent\), call directly; if the tool requires sequencing or error recovery planning, use ReAct.
