So what
Standard evaluations mask agent detector failure rates, creating false confidence when deploying autonomous workflows in security-sensitive production environments.
Do what
Review agent monitoring mechanisms with the model risk management team to ensure evaluations account for variable attack frequency and unseen tool calls.
