SummaryThe paper proposes pre-action verification as an underused oversight mechanism for LLM agents. It evaluates deterministic verifiers across shell commands (catching 95.8% of invalid commands at 10% false positives) and code edits, finding location-anchored edit formats fail silently while content-anchored ones fail cleanly. Benchmarks, verifiers, and guards are released.
Why it mattersQuantified findings on silent agent failures across two modalities with reusable verification artifacts. Directly applicable to builders and evaluators of LLM agent systems.
