  title: Vantage Review Cost Recommendations Against Providers
  summary: List available cost providers, then pull optimization recommendations and branch on whether any exist.
  description: >-
    A Vantage savings-review pattern. The workflow first lists the available
    Cost Providers so the caller knows which clouds Vantage is analyzing, then
    retrieves the current cost-optimization Recommendations. It branches: when at
    least one recommendation is returned it ends having surfaced them, and when
    none are returned it falls through to an explicit no-recommendations end.
    Every step spells out its request inline — including the Bearer token — so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
