  title: Amazon EC2 Auto Scaling Schedule Capacity Change
  summary: Create a scheduled scaling action on a group and confirm it is registered.
  description: >-
    Schedules a future or recurring capacity change for an Auto Scaling group.
    The workflow puts a scheduled update group action with the requested sizing
    and recurrence, then describes the group's scheduled actions to confirm the
    action was registered and to capture its ARN and start time. 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.
