  title: Azure DevOps Open a Pull Request and Start a Review Thread
  summary: Create a pull request, confirm it, and add an opening review comment thread.
  description: >-
    Opens a pull request from a source branch into a target branch and kicks off
    the review conversation. The workflow creates the pull request, fetches it to
    confirm its active status and capture the head commit of the source branch,
    and then adds an active comment thread asking reviewers to begin. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
