  title: Amazon Elastic Transcoder List Jobs by Pipeline and Read the First Job
  summary: List the jobs currently in a pipeline, then read detailed information about the first job returned.
  description: >-
    A read-oriented inspection flow. The workflow confirms a pipeline exists,
    lists the jobs currently in that pipeline in chronological order, and then
    reads the first job in the list to retrieve its full status and details.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
