PyCache Trap: The Inspection-Execution Gap in Agent Skill Scanners

Jie Liao, Simeng Qin, Wenqi Ren وآخرون · 2026

Agent skills combine instructions with executable resources, giving third-party packages access to an agent's runtime. Existing skill scanners inspect documentation and visible source, but Python may execute a bundled bytecode cache with different behavior. We study this gap between inspection and execution through PyC …

Representation--Behavior Alignment for Explainable Weakly-Supervised Video Anomaly Detection

Chao Huang, Pengfei Wei, Kaige Li وآخرون · 2026

Multimodal Large Language Models (MLLMs) provide a natural way to make video anomaly detection more explainable. However, their final decisions do not always fully use the discriminative information contained in their hidden states, an issue we refer to as representation--behavior misalignment. We decompose this gap in …

RoMod: Temporal Routing Modulation via Mixture-of-Experts for Video Anomaly Detection

Chao Huang, Pengfei Wei, Benfeng Wang وآخرون · 2026

Intermediate-layer features from multimodal large language models have shown strong potential for video anomaly detection (VAD), yet the origin of their discriminative power remains unclear. We study this question using sparse mixture-of-experts (MoE) models, whose explicit expert structure and sparse activation make t …
