  title: Claude Find Latest Batch Results
  summary: List recent message batches, inspect the most recent one, and retrieve its results if it has ended.
  description: >-
    A batch-discovery and retrieval flow. The workflow lists the most recent
    message batches in the workspace, retrieves the full status of the newest
    batch to confirm whether its processing has ended, and — when it has —
    streams that batch's results as a JSONL file. A branch ensures results are
    only fetched once the batch's processing_status is ended. Every step spells
    out its request inline — including the required x-api-key and
    anthropic-version headers — so the flow can be read and executed without
    opening the underlying OpenAPI description.
