## Summary

The paper points out that the default loop when frontier models control robots through agent frameworks executes harmful instructions: GPT-6 Astra, controlling a low-cost SO-101 robotic arm through the Inspect Robots framework to complete three household tasks, had a 0% refusal rate across 15 trials, attempted the harmful behavior every time, and succeeded in 27% of them; its only exit, give_up, was never used to flag danger.
