Safety Sentry: Context-Aware Human Intervention via EXECUTE-ASK-REFUSE Routing

Jul 16, 2026

A new preprint introduces Safety Sentry, a guard model for LLM agents that routes actions into three categories: EXECUTE, ASK, or REFUSE, rather than using only binary safe/unsafe labels. The model enables per-instance, context-aware decisions and allows risk tolerance to be adjusted at inference time with a single threshold, without retraining. Safety Sentry demonstrates improved accuracy and safety recall compared to both open-weight and closed-source baseline models.

Why it matters: This work proposes a more nuanced and flexible approach to LLM agent safety, potentially reducing unnecessary interruptions while improving harm prevention.
