VERSE: Verified Self-Evolving Optimizer for Agent Harnesses

Zekai Wang, Yingqiang Ge, Zekun Wang +6

Harness evolution improves an LLM agent's prompts, tools, and workflow, while the optimizer's own tools and procedures often remain fixed. We study whether an optimizer can improve…

DRIFTLENS: Measuring Memory-Induced Reasoning Drift in Personalized Language Models

Xi Fang, Weijie Xu, Yingqiang Ge +3

Personalization changes what a model says to a user; we show that it can also change the reasoning trajectory used to justify the response. Modern LLMs personalize interactions by…

VLAA-GUI: Knowing When to Stop, Recover, and Search, A Modular Framework for GUI Automation

Qijun Han, Haoqin Tu, Zijun Wang +11

Autonomous GUI agents face two fundamental challenges: early stopping, where agents prematurely declare success without verifiable evidence, and repetitive loops, where agents cycl…

Visual Exclusivity Attacks: Automatic Multimodal Red Teaming via Agentic Planning

Yunbei Zhang, Yingqiang Ge, Weijie Xu +3

Current multimodal red teaming treats images as wrappers for malicious payloads via typography or adversarial noise. These attacks are structurally brittle, as standard defenses ne…

RESPOND: Risk-Enhanced Structured Pattern for LLM-driven Online Node-level Decision-making

Dan Chen, Heye Huang, Tiantian Chen +4

Current LLM-based driving agents that rely on unstructured plain-text memory suffer from low-precision scene retrieval and inefficient reflection. To address this limitation, we pr…
