Comprehensive audit logging is essential for tracking agent handoffs, providing the observability needed to diagnose failures, especially silent ones. A well-structured audit trail serves as the ground truth for what happened during an agent interaction.
For each handoff event, the log should capture a set of critical fields in a structured format (e.g., JSON) to be most effective. Essential fields include:
- Sender ID: The unique identifier of the sending agent.
- Receiver ID: The unique identifier of the receiving agent.
- Timestamp: The precise time of the handoff attempt.
- Message Summary/Hash: A summary or hash of the message content to identify the payload without logging sensitive data.
- Verification Result: The outcome of the handoff verification step (e.g.,
ack_received,readiness_confirmed,timeout). - Error Codes: Any errors that occurred during the handoff.
Without this level of detail, debugging complex, asynchronous interactions becomes exceptionally difficult.
