Composing Task-specific Agent Harnesses at Test Time with Reusable Primitives

Peng Kuang, Haibo Jin, Dehao Wu +4

Agent harnesses govern how large language models (LLMs) gather context, invoke tools, verify results, preserve state, and terminate, largely affecting agent performance. However, t…

ANTMAN: Adaptive Need Tracking for Multi-Agent Navigation in Large Information Spaces

Jerry Wang, Haibo Jin, Xiaopeng Yuan +2

Information-seeking agents increasingly operate over information spaces that are too large to process exhaustively. Yet many multi-agent systems organize computation around static…

Beyond Asking: A Pipeline for Personalized Game Generation that Reads Players from Behavior

Yifan Lu, Xiaopeng Yuan, Haohan Wang

Personalized game generation requires inferring a player's abilities and behavioral style from how they play. Large language models have made this inference more attainable than ev…

KV-PRM: Efficient Process Reward Modeling via KV-Cache Transfer for Multi-Agent Test-Time Scaling

Peng Kuang, Haibo Jin, Xiaoyu Han +5

Process Reward Models (PRMs) have been proven to be highly effective in guiding test-time scaling (TTS) methods, which significantly boost the capabilities of LLM-based multi-agent…

EASE-TTT: Evidence-Aligned Selective Test-Time Training for Long-Context Question Answering

Xiaopeng Yuan, Zebin Wang, Suwen Wang +3

Long-context question answering (QA) remains challenging for smaller language models even when answer-bearing evidence is already present in the input. Existing within-context retr…

Closing the Loop on Latent Reasoning via Test-Time Reconstruction

Xiaopeng Yuan, Haibo Jin, Ye Yu +4

Recent work moves intermediate reasoning from natural-language traces into latent or cache-level representations to reduce token overhead and avoid a discrete communication bottlen…

Do Self-Evolving Agents Forget? Capability Degradation and Preservation in Lifelong LLM Agent Adaptation

Ye Yu, Xiaopeng Yuan, Haibo Jin +3

Recent advances in LLM agents enable systems that autonomously refine workflows, accumulate reusable skills, self-train their underlying models, and maintain persistent memory. How…

Learning to Communicate: Toward End-to-End Optimization of Multi-Agent Language Systems

Ye Yu, Heming Liu, Haibo Jin +3

Multi-agent systems built on large language models have shown strong performance on complex reasoning tasks, yet most work focuses on agent roles and orchestration while treating i…

Agent Primitives: Reusable Latent Building Blocks for Multi-Agent Systems

Haibo Jin, Peng Kuang, Ye Yu +2

While existing multi-agent systems (MAS) can handle complex problems by enabling collaboration among multiple agents, they are often highly task-specific, relying on manually craft…

Tracing LLM Reasoning Processes with Strategic Games: A Framework for Planning, Revision, and Resource-Constrained Decision Making

Xiaopeng Yuan, Xingjian Zhang, Ke Xu +5

Large language models (LLMs) are increasingly used for tasks that require complex reasoning. Most benchmarks focus on final outcomes but overlook the intermediate reasoning steps -…
