RedEvoAgent: Automatic Red-Teaming Agent with Experience-Driven Skill Evolution

RedEvoAgent is proposed, a black-box red-teaming agent that distills cross-case attack trajectories into a concise, human-readable attack skill that outperforms fixed and agentic baselines, improves tool efficiency, and transfers across attacker models and target execution harnesses.

Small Agents, Big Gains: Journey-Aware and Critic-Guided Simulation for Long-Horizon Shopping Dialogues

This work proposes a closed-loop Multi-Agent Simulation Framework to synthe-size diverse, faithful, and policy-aligned shopping trajectories, and presents synthetic data that enables a small model to significantly outperform same-size baselines and surpass a large-model baseline.
