LongRCA Bench: Diagnosing Responsible Roles and Root Causes in Long-Horizon Agent Failures

Yunfei Zhang, Boyu Feng, Changhua Pei +14

When a long-horizon agent execution fails, outcome-level evaluation reveals the unsuccessful result but not where the decisive error entered the trajectory. Developers must then in…

A Self-Evolving Framework for Efficient Terminal Agents via Observational Context Compression

Jincheng Ren, Siwei Wu, Yizhi Li +8

As terminal agents scale to long-horizon, multi-turn workflows, a key bottleneck is not merely limited context length, but the accumulation of noisy terminal observations in the in…

EcoGym: Evaluating LLMs for Long-Horizon Plan-and-Execute in Interactive Economies

Xavier Hu, Jinxiang Xia, Shengze Xu +13

Long-horizon planning is widely recognized as a core capability of autonomous LLM-based agents; however, current evaluation frameworks suffer from being largely episodic, domain-sp…

How Far Are We from Genuinely Useful Deep Research Agents?

Dingling Zhang, He Zhu, Jincheng Ren +15

Deep Research Agents (DRAs) aim to automatically produce analyst-level reports through iterative information retrieval and synthesis. However, most existing DRAs were validated on…
