    "incantation": "When a Space needs filesystem access to Hub models, datasets, or buckets, pass one or more `-v`/`--volume` values to `hf repos create` or `hf repos duplicate`. Use `hf://[TYPE/]SOURCE:/MOUNT_PATH[:ro]`; models, datasets, and Spaces mount read-only, while buckets are read-write by default.",
    "examples": [
      "hf repos create <space-id> --type space --space-sdk <sdk> -v hf://<model-id>:/models -v hf://buckets/<owner>/<bucket>:/data",

    "gotchas": [
      "Version: v1.9.0",
      "REPO_ID (required): Destination repo ID for `hf repos create`.",
      "--type space (required): Sets the repository type to Space; `--type` also accepts model or dataset.",

      "-v, --volume TEXT: Repeat to mount volumes. Format: `hf://[TYPE/]SOURCE:/MOUNT_PATH[:ro]`. TYPE allows models, datasets, spaces, or buckets; it defaults to models when omitted. Models, datasets, and Spaces are always read-only; buckets are read-write by default. The `:ro` suffix selects read-only mounting. The docs do not describe volume values as mutually exclusive.",
      "Prerequisite: The CLI repository guide says the machine must be logged in and the user must own the repository or have write permission in its organization.",
