Agent Error Dataset: Scaling 50,000 Error--Diagnosis Pairs for Failure Analysis and Error-Aware Post-Training

Kunlun Zhu, Xuyan Ye, Yibo Li, Cheng Qian, Beibin Li

his paper introduces the Agent Error Dataset (AED), a large collection of 50,000 error-diagnosis pairs for text-based LLM agents. The core method involves a five-stage pipeline (AET) to automatically identify agent failures, diagnose their causes, and propose corrections using existing execution traces. The main contribution is providing a scalable resource for analyzing agent failures and developing error-aware post-training techniques, enabling agents to learn from their mistakes without re-running entire rollouts.

PivotOPD: Learning to Recover from Pivotal Mistakes in Multi-Turn Agents

Yinghui He, Yapei Chang et al.

PivotOPD addresses the compounding errors in multi-turn language agents by identifying and correcting "pivotal mistakes" – actions that significantly derail task progress. The core method involves an on-policy distillation framework that trains agents to both …

JuryFlow: Disagreement-Guided Human-in-the-Loop Multi-Agent Evaluation

Mufeng Yang, Junwei Yu et al.

JuryFlow addresses the unreliability of LLM judges by treating inter-judge disagreement as a valuable signal. Its core method decomposes responses into atomic claims, uses heterogeneous judges to provide per-claim verdicts, and builds a disagreement graph. The…

Figure 1. Conceptual overview of JuryFlow. Multiple LLM Agents extract Claims from a candidate response and produce per-claim verdicts, forming a Disagreement Graph that surfaces conflicts. A Human selects the most critical disagreement point—the only human intervention (made automatically by entropy ranking in our experiments). The system then performs Propagated Re-Evaluation across related claims and historical cases, and abstracts the correction into a Rubric Update that all agents inherit, closing the loop. A conceptual illustration showing the JuryFlow pipeline from left to right. Three AI robot icons (labeled Agents) each produce a document icon (labeled Claim). Arrows flow from agents and claims into a central disagreement graph, a dense network of interconnected nodes with some edges highlighted in amber to indicate conflict. A human selects the highest-entropy focal node (automated in our experiments). Dashed arrows lead rightward to a second, lighter graph representing Propagated Re-Evaluation, and finally to a checklist document icon labeled Rubric Update.
