ComfyUI Node Development Skill

A comprehensive skill for developing ComfyUI custom nodes following production best practices.

Overview

This skill provides guidance for creating ComfyUI custom nodes, from basic structure to advanced patterns like memory management, batch processing, and model integration.

Installation

Local (Repository Only)

cp -r ComfyUI-node-development-skill ~/.claude/skills/

Global Installation

ln -s "$(pwd)/ComfyUI-node-development-skill" ~/.claude/skills/comfyui-node-development

Usage

This skill automatically activates when you mention:

• "create ComfyUI node"
• "build custom node"
• "ComfyUI development"
• "node for ComfyUI"
• "custom ComfyUI"

Quick Start

Basic Node Template

class MyCustomNode:
    """Description of what this node does."""
    
    @classmethod
    def INPUT_TYPES(cls):
        return {
            "required": {
                "input_name": ("INPUT_TYPE", {"default": value}),
            }
        }
    
    RETURN_TYPES = ("OUTPUT_TYPE",)
    FUNCTION = "execute"
    CATEGORY = "custom/category"
    
    def execute(self, input_name):
        # Your logic here
        return (output,)

Register Your Node

In __init__.py:

from .my_module import MyCustomNode

NODE_CLASS_MAPPINGS = {
    "MyCustomNode": MyCustomNode,
}

NODE_DISPLAY_NAME_MAPPINGS = {
    "MyCustomNode": "My Custom Node",
}
