arXiv:2601.22136v2 Announce Type: replace-cross Abstract: Agent safety benchmarks measure whether a monitor detects harm, not when. Yet timing is the difference between intervention and autopsy. We introduce StepShield, the first benchmark that treats detection timeliness as a first-class metric. On 9,429 incident-grounded code-agent trajectories, we define the Early Intervention Rate (EIR): the fraction of detected rogue trajectories where the alert fires within a k-step window after the divergence point, isolating timing quality from coverage. This metric exposes what we call the Forensics T
The rapid advancement and deployment of AI agents necessitate robust safety mechanisms, pushing research towards more nuanced and effective intervention strategies.
Improving the timeliness of rogue AI agent detection and intervention is critical for mitigating risks and building public trust in autonomous systems.
The focus in AI safety benchmarks shifts from mere detection to the crucial aspect of timely intervention, allowing for better evaluation of protective measures.
