Adversarial evaluation tests a system from the perspective of someone trying to find weaknesses rather than someone following the expected path. Evaluators generate difficult cases, conflicting objectives, and boundary conditions to see whether the system produces outcomes its designers did not intend.
A useful evaluation looks for failures in more than one direction. It can test whether prohibited behavior slips through and whether acceptable behavior is blocked, which helps distinguish overly loose rules from overly restrictive ones.

Adversarial evaluation tests an AI system with deliberately difficult, deceptive, or hostile inputs. The goal is to discover failures that ordinary examples may not reveal before those failures appear in real use.
For example, evaluators can try conflicting instructions and manipulative tool outputs to see whether an agent breaks its security rules. Passing the tested attacks is useful evidence, but it does not prove that every possible weakness has been found.
What does adversarial evaluation reveal?
It can reveal loopholes, missing boundaries, conflicting rules, unsafe allowances, and unnecessary refusals.
Is adversarial evaluation the same as proving safety?
No. It finds important failures and improves coverage, but passing a bounded set of tests does not prove that every possible case is safe.
