37.5 Auditability and replay

Overview and links for this section of the guide.

The Black Box Problem

When an agent fails, you need to know why. "It didn't work" is not useful.

You need to log the entire Trace: - Step 1: Input "X", Output "Y". - Step 2: Tool Call "Z", Tool Result "Error". - Step 3: Final Answer "I failed".

Tracing

Store these traces in a database or a specialized tool (like LangSmith or Arize). This allows you to "replay" the session with a human in the loop to see where the logic broke.
