      "source (required): First path; for this task, a repository or Bucket path. A trailing `/` copies the folder contents without nesting the folder itself.",

      "Prerequisite: Have read access to the source repository or Bucket and write access to the destination Bucket.",
      "Prerequisite: Remote-to-remote copies require the source and destination to be in the same storage region.",
      "Copying from a Bucket to a Repository is not yet supported.",
