ComfyUI V3 Custom Nodes (Server-Side)

ComfyUI baseline: v0.12.0 (Comfy API v0_0_2). Update this line when revising the skill.

Scope

• Focus on server-side V3 nodes (Python).
• Exclude client-server extension patterns and frontend-only extensions.

Quick Workflow

1. Choose API adapter: comfy_api.v0_0_2 for stability or comfy_api.latest for newest features.
2. (Optional) Scaffold a nodepack using comfy node scaffold.
3. Implement a V3 node with io.ComfyNode.define_schema() and execute().
4. Return io.NodeOutput (or tuple/dict) from execute().
5. Register nodes via ComfyExtension.get_node_list() and comfy_entrypoint().
6. Restart ComfyUI and validate in UI/API.
