AI agent observability records enough evidence to understand what a workflow did and whether it achieved the intended result. Capture inputs, retrieved sources, tool actions, approvals, and outcomes with appropriate privacy controls. Do not confuse a model’s explanation with reliable evidence of its hidden internal reasoning or of a completed external action.
Define a trace around the business task
Assign a stable identifier to each workflow run and connect related events across systems. Record the task type, triggering event, configuration version, and relevant record identifiers. A callback workflow should connect the incoming enquiry, prepared summary, review, and final task creation. Keep identifiers consistent when the workflow pauses and resumes. Without that connection, separate application logs may show that activity occurred while leaving the operator unable to determine whether one customer’s request was actually completed.
Capture observable decisions and results
Log which sources were retrieved, which tool was requested, validated arguments, authorization decisions, and returned status. Record approval references and changes to business state. Distinguish attempted actions from confirmed outcomes. If a model produces a rationale, label it as generated text rather than proof of causation. For a booking, the authoritative evidence is the confirmed appointment record and its relationship to the request, not a sentence saying the customer has been booked.
Minimize sensitive information in traces
Avoid recording secrets, payment details, or entire customer documents by default. Use redaction, access controls, and retention rules appropriate to the workflow. Preserve source references when they provide sufficient evidence without copying the whole content. Restrict who can inspect raw conversations and who can export them. Test redaction using realistic examples rather than assuming it covers every field. Observability should help resolve incidents without creating an unnecessary second store of private business information.
Alert on actionable failures
Define alerts for unauthorized action attempts, failed handoffs, repeated retries, stuck tasks, and unexpected cost or latency. Route each alert to an accountable person with enough context to investigate. Avoid a stream of low-value notifications that staff learn to ignore. Use NIST’s AI Risk Management Framework to support risk ownership and monitoring. Check that an alert leads to a response, because detecting an issue without a working escalation path leaves the workflow unresolved.
Connect traces to evaluation and operations
Review representative successful runs as well as failures. Turn incidents into test cases and use trace evidence to identify whether the problem came from retrieval, permissions, tools, or communication. Measure correct completion, exception age, detection time, and recovery time alongside cost. Test whether an operator can reconstruct a failed run without asking the original developer for help. A useful observability system makes the next operational decision clearer and gives the team evidence for improving or stopping the workflow.
