[frontier] How do you keep computer-use agents from clicking the wrong thing?

Deploy an out-of-band guardrail that independently verifies both \(1\) the visual click target and \(2\) the agent's stated reasoning against deployment-specific knowledge, and blocks the action if either channel disagrees.

Journey Context:
The same coordinate can be benign or privileged depending on what is actually on screen. Current benchmarks ask whether a task succeeded, not whether the agent acted on the correct object; OSWorld-MCP reports 56.7% of CUA actions miss their target. Dual-channel contrastive classification catches visual target mismatches and dangerous intent behind visually innocent controls better than either check alone.
