Free to Look, Free to Reason: Simple LLM Harnesses Outdiagnose Hand-Crafted Root Cause Analysis Agents
An abstract reports that three minimally prescriptive LLM harnesses outperformed five published RCA agents on a benchmark of 90 validated cases.
Why it matters: For agent builders, the reported results challenge the assumption that hand-crafted RCA workflows outperform giving a capable model room to investigate. The abstract also flags a practical trade-off: more reasoning effort brought little accuracy change while substantially increasing time, and every Pareto-optimal run in cost or time among runs beating the best non-LLM method used a simple harness.
