Web UI Extension

Use this sub-skill when the task is about making File -> Save As Script appear inside ComfyUI or understanding the browser-side export route.

Typical user requests

• Install the repository as a ComfyUI custom node.
• Make the Save As Script menu item appear after restarting ComfyUI.
• Explain how the browser export button works.
• Diagnose why /saveasscript or the extension route fails.
• Understand how __init__.py and js/save-as-script.js cooperate.
• Verify that the extension is discoverable through custom_nodes.

What this sub-skill owns

• The repo root extension entrypoint in __init__.py.
• The frontend asset in js/save-as-script.js.
• ComfyUI discovery patterns and install placement.
• Browser-side default filename behavior.
• Extension-specific troubleshooting and restart guidance.

What this sub-skill excludes

• CLI export flags and generated-script runtime details.
• Node ordering, seed handling, or torch bootstrap in exported Python.
• Generic ComfyUI model-serving or diffusion workflows unrelated to this extension.

Read these first

• references/install-and-discovery.md for installation and browser flow.
• references/troubleshooting.md for extension-specific failures.
• scripts/check_discovery.py for a quick layout check when you want to confirm the repo is discoverable.

Workflow

1. Confirm that the user wants the in-UI export path rather than the CLI exporter.
2. Place the repository where ComfyUI can discover it through custom_nodes or an external path configuration.
3. Install the dependencies into the interpreter that launches ComfyUI.
4. Restart ComfyUI and look for File -> Save As Script.
5. If the menu item is present but the request fails, inspect the /saveasscript route and extension logs.

Routing hints

Choose this sub-skill when you see any of these signals:

• Save As Script
• File -> Save As Script
• custom_nodes
• extra_model_paths.yaml
• /saveasscript
• WEB_DIRECTORY
• workflow_api.py as the browser download filename
• ComfyUI extension install or restart issues

Success criteria

A future agent should be able to:

• explain where the repository must live for ComfyUI to load it,
• describe the browser command and the POST payload shape,
• and troubleshoot why the extension is not visible or the route does not respond.
