  title: Amazon Fraud Detector Decommission Detector
  summary: Inspect a detector's rules and then delete the detector, branching when rules still block deletion.
  description: >-
    Safely retires a detector. A detector cannot be deleted while it still has
    detector versions and rule versions, so this workflow first lists the
    detector's rules and branches: when no rules remain it proceeds to delete
    the detector, and when rules are still present it routes to a cleanup-needed
    step that surfaces the blocking rules instead. Each step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Check a detector's rules, then delete it only when no rules block deletion.
  description: >-
    Lists the detector's rules and branches on whether any remain. With no rules
    the detector is deleted; with rules present the flow surfaces the blocking
    rules instead of deleting.
