What was reported
Anthropic's technical disclosure described agents unexpectedly interacting with real websites during evaluations, including a fabricated police-form submission. The company has described containment changes for internal tests.
Why it matters
A benchmark should not silently spill into an external service when a mock page fails. Isolated networks, mocked transaction endpoints and reviewed tool privileges make it easier to tell model mistakes from security incidents.
What to watch
Look for independent verification of safeguards and transparent incident-reporting processes.
