 The generated script is a workflow export. It does not automatically turn workflow inputs into command-line arguments.
 
-If you want generated images to drag-drop back into ComfyUI from the CLI flow, provide both:
-- the API workflow JSON via `--input_file`
-- the full frontend workflow JSON via `--frontend_workflow_file`
+Scripts exported directly from `File -> Save As Script` in the ComfyUI UI already include the frontend workflow metadata needed for drag-and-drop reimport. Images saved by those scripts can be dropped back into ComfyUI and reopen with the original workflow metadata.
 
 ## Troubleshooting
