Dify’s custom tool feature allows you to define responses as files within an OpenAPI schema, but the exact usage isn’t very clear to me.
For example, DALL-E and Stable Diffusion returns images as responses. How can I define this in my OpenAPI schema?

my tool schema now

      responses:
        '200':
          description: "Successful response returning an array of base64 encoded file data"
          content:
            application/json:
              schema:
                type: object
                properties:
                  files:
                    type: array
                    items:
                      type: string
                      format: byte
                      description: "Base64 encoded file content"
                required:
                  - files

Also WIP for Array[File] response?

The PR appears to address only the input. For the output, perhaps the plugin feature in version 1.0 would be a better option?
