  title: Varonis User High-Severity Investigation
  summary: Find a user's high-severity alerts, pull the top alert's events, and annotate it.
  description: >-
    A user-centric insider-threat workflow. It searches DatAlert for
    high-severity alerts attributed to a specific user name, retrieves the
    forensic events behind the highest-priority alert for that user, and records
    an annotation note on the alert so the user investigation is documented.
    Each step inlines its request so the flow can be read and executed without
    opening the underlying OpenAPI description.
