Automating Agent Failure Diagnosis via Root-Cause Search
September 10, 2026
Long-horizon agent execution logs present a massive search problem for automated root-cause attribution due to sparse, distributed error signals. One-shot LLM diagnostic methods fail as traces grow, necessitating approaches that can traverse long-range dependencies to identify specific failure points.
