  title: Azure DevOps Create, Update, and Comment on a Work Item
  summary: Create a work item, transition its state, and append a comment in one flow.
  description: >-
    A core Azure Boards authoring pattern. The workflow creates a new work item
    of the requested type using a JSON Patch document, transitions the newly
    created item to a working state with a second JSON Patch, and then appends a
    human-readable comment describing the change. Note that work item create and
    update use the application/json-patch+json media type, while the comment
    endpoint uses plain application/json. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
