ComfyUI Local Skill

This skill allows OpenClaw to generate images by connecting to a ComfyUI instance running on the local network.

Setup

Server Address: Set the COMFYUI_SERVER_ADDRESS environment variable to your PC's IP and port (e.g., http://192.168.1.119:8189).
API Mode: Ensure "Enable Dev mode" is turned on in your ComfyUI settings to allow API interactions.

Usage

Generate an Image

Run the internal generation script with a prompt:

python3 {skillDir}/scripts/comfy_gen.py "your image prompt" $COMFYUI_SERVER_ADDRESS

Use a Custom Workflow

Place your API JSON workflows in the workflows/ folder, then specify the path:

python3 {skillDir}/scripts/comfy_gen.py "your prompt" $COMFYUI_SERVER_ADDRESS --workflow {skillDir}/workflows/my_workflow.json

Features

SDXL Default: Uses a high-quality SDXL workflow (Juggernaut XL) by default.
Auto-Backup: Designed to save images to image-gens/ and can be configured to sync to local document folders.
Custom Workflows: Supports external API JSON workflows saved in the workflows/ folder. The script will automatically try to inject your prompt and a random seed into the workflow nodes.

Implementation Details

The skill uses a Python helper (scripts/comfy_gen.py) to handle the WebSocket/HTTP handshake with the ComfyUI API, queue the prompt, and download the resulting image.
