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",
}
