A clear handoff separates observation from explanation. Include the request identifier, environment, time window and the span you investigated. Explain what you measured before describing what you think caused it. Give the receiving team one actionable question and a practical way to reproduce or compare the behavior. Record the effect on the user journey without adding unsupported estimates of lost revenue or impact. Remove credentials, personal data and customer payloads before sharing examples. A concise technical summary preserves enough context for the next person to continue the work.
