Towards Robust Tool Use in Agents via Experience-Driven Adaptive Guidance

Can Wang, Haoran Chen, Li Yu +4

The performance bottleneck of agents is increasingly shifting from model capability to the robustness of their execution processes. Tools play a central role as the primary interfa…

From Simple QA to Deep Research: A Verifiable Benchmark Constructed through Iterative Task Evolution

Can Wang, Haoran Chen, Haowen Gao +3

Deep research benchmarks require expert-level tasks and reliable evaluation grounded in task-specific knowledge. Existing benchmarks rely heavily on expert authoring or pre-existin…

SkillAudit: Ground-Truth-Free Skill Evolution via Paired Trajectory Auditing

Haowen Gao, Haoran Chen, Can Wang +5

Agent skills are structured procedural packages that guide frozen LLM agents in specialized workflows. Skills rarely remain sufficient after deployment: edge cases, API changes, an…

Voting with the Graph: Stable RLAIF via Topological Consistency Maximization

Boyin Liu, Zhuo Zhang, Sen Huang +8

Reinforcement Learning from AI Feedback (RLAIF) relies on LLM judges as preference measurement instruments, yet these instruments are fundamentally limited by random measurement er…

Auto-Rubric: Learning From Implicit Weights to Explicit Rubrics for Reward Modeling

Lipeng Xie, Sen Huang, Zhuo Zhang +9

Conventional reward modeling relies on gradient descent over neural weights, creating opaque, data-hungry "black boxes." We propose a paradigm shift from implicit to explicit rewar…

Co-Sight: Enhancing LLM-Based Agents via Conflict-Aware Meta-Verification and Trustworthy Reasoning with Structured Facts

Hongwei Zhang, Ji Lu, Shiqing Jiang +11

Long-horizon reasoning in LLM-based agents often fails not from generative weakness but from insufficient verification of intermediate reasoning. Co-Sight addresses this challenge…
