  title: AWS SAR Decommission Application
  summary: Confirm an application exists by reading it, then delete it to decommission it.
  description: >-
    Safely retires a serverless application. The workflow first reads the
    application to confirm it exists and capture its identity, then deletes it.
    The list operation is also run afterward so the caller can confirm the
    application is no longer present. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
