  title: Azure DevOps Review the Oldest Active Pull Request
  summary: List active pull requests, open the oldest, and add a review comment.
  description: >-
    Drives a lightweight review-queue pattern over Azure Repos. The workflow
    lists active pull requests in a repository, branches on whether any are open,
    fetches the first (oldest) active pull request with its commits expanded, and
    posts an active comment thread asking for a review. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
