Why it matters
Task-success rates hide agents that finish by unsafe or incoherent means. Encoding invariants as executable rules and replaying them over real trajectories is an evalA repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.Full definition → pattern that extends past robotics.

AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
