  title: Amazon EC2 Auto Scaling Audit Launch Configuration Usage
  summary: Resolve a launch configuration, then describe the group using it to audit its policies.
  description: >-
    Audits how a launch configuration is wired into a running group. The
    workflow describes the named launch configuration to capture its ARN and
    image, describes the Auto Scaling group that references it to capture its
    current sizing, and then describes the scaling policies attached to that
    group. Every step spells out the AWS query-protocol Action and Version
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
