ComfyUI Skills for OpenClaw

Turn your ComfyUI workflows into callable skills for AI agents. Any agent that can run shell commands — Claude Code, Codex, OpenClaw — can discover, execute, and manage ComfyUI workflows through a single CLI.

Install

Step 1: Clone the project

For OpenClaw

cd ~/.openclaw/workspace/skills
git clone https://github.com/HuangYuChuh/ComfyUI_Skills_OpenClaw.git comfyui-skill-openclaw
cd comfyui-skill-openclaw
cp config.example.json config.json

For Claude Code

cd ~/.claude/skills
git clone https://github.com/HuangYuChuh/ComfyUI_Skills_OpenClaw.git comfyui-skill
cd comfyui-skill
cp config.example.json config.json

For Codex

cd ~/.codex/skills
git clone https://github.com/HuangYuChuh/ComfyUI_Skills_OpenClaw.git comfyui-skill
cd comfyui-skill
cp config.example.json config.json

Step 2: Install the CLI

pipx install comfyui-skill-cli

Or with pip:

pip install comfyui-skill-cli

Step 3: Verify

comfyui-skill server status
comfyui-skill list

That's it. The CLI reads config.json and data/ from the project directory.

Web UI dependencies (optional, only needed if you want the management interface):

pip install -r requirements.txt

---

CLI Usage

The CLI is the primary way to interact with ComfyUI Skills. All commands support --json for structured output.

Quick Start

# Check server
comfyui-skill server status

# List workflows
comfyui-skill list

# Execute a workflow
comfyui-skill run local/txt2img --args '{"prompt": "a white cat"}'

# Import a new workflow from JSON
comfyui-skill workflow import ./my-workflow.json --check-deps

# Upload an image for img2img workflows
comfyui-skill upload ./photo.png

Full Command Reference

Category	Command	Description

	comfyui-skill server enable/disable <server_id>	Toggle server
	comfyui-skill server remove <server_id>	Remove server
Dependencies	comfyui-skill deps check <workflow_id>	Check missing nodes and models
	comfyui-skill deps install <workflow_id> --all	Install all missing deps
Config	comfyui-skill config export --output <path>	Export config bundle

Web UI (Optional)

A local web interface for visual workflow management. Not required for Agent usage — the CLI covers all functionality.

Launch

pip install -r requirements.txt   # first time only
./ui/run_ui.sh                    # macOS/Linux
# or: ui\run_ui.bat               # Windows

Visit http://localhost:18189.

Capabilities

• Upload workflows exported from ComfyUI (API Format)
• Configure parameter mappings with a visual editor
• Manage multiple servers and workflows in one place
• Drag to reorder, search and filter across servers
• Available in English, Simplified Chinese, and Traditional Chinese

Frontend source lives in a separate repository.

---

Workflow Setup

Before you start, make sure your ComfyUI server is running (default: http://127.0.0.1:8188).

Option A: Import via CLI (Recommended)

# Import a workflow JSON — auto-detects format, converts if needed, generates schema
comfyui-skill workflow import ./my-workflow.json

# Check and install dependencies
comfyui-skill deps check local/my-workflow
comfyui-skill deps install local/my-workflow --all

# Verify
comfyui-skill run local/my-workflow --args '{"prompt": "test"}'

Option B: Import via Web UI

1. Open the Web UI at http://localhost:18189
2. Upload a workflow JSON exported from ComfyUI with Save (API Format)
3. Select which parameters to expose to agents
4. Save the mapping

Option C: Manual Setup

Expand for manual config file setup

1) Edit config.json

{
  "servers": [
    {
      "id": "local",
      "name": "Local",
      "url": "http://127.0.0.1:8188",
      "enabled": true,
      "output_dir": "./outputs"
    }
  ],
  "default_server": "local"
}

2) Place workflow files

data/local/my-workflow/
  workflow.json  # ComfyUI API-format export
  schema.json    # Parameter mapping

3) Write schema.json

{
  "description": "My workflow",
  "enabled": true,
  "parameters": {
    "prompt": {
      "node_id": 10,
      "field": "prompt",
      "required": true,
      "type": "string",
      "description": "Prompt text"
    }
  }
}

Workflow Requirements

• Must be exported in ComfyUI API format (click Save (API Format) in ComfyUI)
• Must end with a Save Image node (or equivalent image output node)

---

Multi-Server Management

Manage multiple ComfyUI servers and route jobs to different hardware.

Core Concepts

• Dual-layer toggles: Both servers and workflows have independent enable/disable. Agents only see workflows where both are enabled.
• Namespacing: Workflows are identified as <server_id>/<workflow_id> (e.g. local/txt2img vs remote-a100/txt2img).

CLI

comfyui-skill server add --id remote --name "Remote GPU" --url http://10.0.0.1:8188
comfyui-skill server list
comfyui-skill server disable remote

Configuration Migration

# Export
comfyui-skill config export --output ./backup.json

# Preview import
comfyui-skill config import ./backup.json --dry-run

# Apply import
comfyui-skill config import ./backup.json

All server settings can also be managed through the Web UI.

---

Updating

./update.sh

This pulls the latest code, syncs frontend assets, and installs new dependencies. You can also run git pull manually.

To update the CLI:

pipx upgrade comfyui-skill-cli

---

Common Issues

• HTTP 400 on /prompt: The workflow payload or parameter values are invalid.
• No images returned: The workflow is missing a Save Image node.
• Connection failed: Check that config.json has the correct server URL.
