Building a Foundational Guardrail for General Agentic Systems via Synthetic Data

Yue Huang, Hang Hua, Yujun Zhou +11

While LLM agents can plan multi-step tasks, intervening at the planning stage-before any action is executed-is often the safest way to prevent harm, since certain risks can lead to…
