Verification gates stop silent policy‑violations in tool‑using LLM agents
Tool-using LLM agents can silently breach deployment policies, producing wrong states without error signals. The authors demonstrate deterministic, read‑only verification gates that catch these violations, boosting benchmark success from 29.6% to 42.0% on gpt‑4o‑mini. This simple safety layer stops a hidden class of policy‑violating writes.
