What you'll learn

Check What the Agent Actually Did

Compare the final message, resulting state, and retained trace to detect plausible but incorrect success.

Test the Evaluator Against Known Mistakes

Use labeled cases and held-out tasks to check false passes, false failures, and evaluator leakage.

Decide Whether an Agent Change Should Ship

Compare versions on the same tasks and weigh uncertainty and critical failures before release.

Why this topic matters

An agent can report success even when its actions produced the wrong result. Learn to compare its final message with the resulting state, test whether an evaluator can detect mistakes, and decide whether a change deserves release. We will reuse worked agent examples to examine evidence, held-out tasks, and critical failures.
