  title: GitLab Retire an Instance-Level CI Variable
  summary: Confirm an instance CI variable exists, then delete it.
  description: >-
    An admin CI cleanup flow. The workflow reads an instance-level CI/CD variable
    by key to confirm it exists, branches on the result, and deletes it when
    present. When the variable is already absent the flow ends without action.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
