Why it matters

Your agent called tool B before tool A, and B has a dependency on A. You did not catch it because nothing in your code audits agents. The telemetry does. Dat from Arize AI walks through what observability actually means when the system you are debugging is nondeterministic and the execution path changes with every run.
