HarnessCompass: Guiding Automatic Harness Evolution toward Generalizable and Effective Agent Harnesses

Luan Zhang, Ruochen Zhou, Dandan Song +9

Harness design plays a critical role in agent performance by shaping how large language models (LLMs) perceive, reason over, and act within executable environments. Recent work has…

Anticipate and Learn: Unleashing Idle-Time Compute in Proactive Agents

Haoyi Hu, Qirong Lyu, Xianghan Kong +7

While AI agents demonstrate remarkable capabilities in reasoning and tool use, they remain fundamentally reactive: they compute responses only after explicit user prompts. This par…

SkillEvolBench: Benchmarking the Evolution from Episodic Experience to Procedural Skills

Yingtie Lei, Zhongwei Wan, Jiankun Zhang +13

Large language model (LLM) agents accumulate rich episodic trajectories while solving real-world tasks, but it remains unclear whether such experience can be distilled into reusabl…

PIVOT: Bridging Planning and Execution in LLM Agents via Trajectory Refinement

Tuo Zhang, Alin-Ionut Popa, Yan Xu +2

Large language model (LLM)-based agents frequently generate seemingly coherent plans that fail upon execution due to infeasible actions, constraint violations, and compounding erro…

Discover and Prove: An Open-source Agentic Framework for Hard Mode Automated Theorem Proving in Lean 4

Chengwu Liu, Yichun Yin, Ye Yuan +7

Most ATP benchmarks embed the final answer within the formal statement -- a convention we call "Easy Mode" -- a design that simplifies the task relative to what human competitors f…

Teaching LLMs According to Their Aptitude: Adaptive Reasoning for Mathematical Problem Solving

Xin Xu, Yan Xu, Tianhao Chen +9

Existing approaches to mathematical reasoning with large language models (LLMs) rely on Chain-of-Thought (CoT) for generalizability or Tool-Integrated Reasoning (TIR) for precise c…
