BridgeGuard: Explicit Safety Drift for Diffusion-based Autonomous Driving

Diffusion-based driving planners capture diverse behaviors but can generate unsafe trajectories under distribution shift. We propose BridgeGuard, a safety-constrained diffusion planning method that progressively strengthens a constraint term during denoising to drive intermediate trajectories toward a scene-dependent s...

SkillSentry: Reliable Skill Execution for LLM Agents via Runtime Assurance

SkillSentry is proposed, a skill-oriented runtime assurance framework built upon a new domain-specific language (DSL) for representing runtime guidance for skill execution that improves the task success rate of LLM agents by 24.1% across skills, on average, while exhibiting lower variability across repeated runs.
