  title: Jira Transition an Issue to a New Status
  summary: Read an issue, discover its legal transitions, apply one, and verify the new status.
  description: >-
    Jira transitions cannot be hard-coded. The set of transitions available to a
    caller depends on the issue's current status, the project workflow, and the
    caller's permissions, so a durable integration always discovers transitions
    at runtime rather than storing a transition id. This workflow reads the
    issue, lists the transitions actually available on it, performs the chosen
    transition, and re-reads the issue to confirm the status moved. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.

  summary: Move a Jira issue through its workflow using a runtime-discovered transition.
  description: >-
    Reads the current status of an issue, discovers the transitions available
    from that status, applies the requested transition with optional resolution
    fields, and verifies the resulting status.
  inputs:
    type: object
    required:
    - issueIdOrKey
    - transitionId
    properties:
      issueIdOrKey:
        type: string
        description: The id or key of the issue to transition (e.g. PROJ-123).
      transitionId:
        type: string
        description: >-
          The id of the transition to perform, selected from the transitions
          discovered by the listTransitions step.
      resolutionName:
        type: string
        description: >-
          The name of the resolution to set during the transition (e.g. Fixed).
          Only valid when the transition's screen exposes the resolution field.
  steps:
  - stepId: readIssue
    description: >-
      Read the issue and capture its current status so the transition can be
      confirmed as an actual change rather than a no-op.

  - stepId: listTransitions
    description: >-
      List the transitions the caller can perform on this issue from its current
      status, expanding transition fields so required screen fields are visible.
