Researchers have developed a new framework called SOAP (Spectral scOring with Attention-guided Propagation) for attributing failures in LLM agents. This method can identify critical steps leading to task failure using only failure trajectories, without requiring step-level labels or successful examples. SOAP constructs a spectral reference space and assigns error scores to each step, then uses attention patterns to propagate downstream error evidence to its likely upstream sources, outperforming existing baselines in experiments.
