  title: Dynatrace Add a Comment to a Problem and Read the Thread
  summary: Confirm a problem, post a collaboration comment, and list the full comment thread.
  description: >-
    Supports collaborative incident handling on a Dynatrace problem. The
    workflow reads the problem to confirm it exists and is still open, adds a
    comment carrying an external context reference, and then lists all comments
    on the problem to return the updated thread. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
