  title: Oracle Cloud Teardown VCN Network
  summary: List subnets in a VCN, delete the first subnet, then delete the VCN itself.
  description: >-
    Cleanly decommissions a virtual cloud network by removing dependent
    resources first. The workflow reads the VCN, lists its subnets, deletes the
    first subnet returned, and then deletes the VCN. Every step spells out its
    request inline so the teardown flow can be read and executed without opening
    the underlying OpenAPI description.
