name: on-this-day-art version: 1.0.0 description: | Daily AI image generation from Wikipedia On This Day events using local ComfyUI. Use when user wants daily historical images, on this day art, or local AI image generation workflow. Does NOT: use cloud APIs, generate videos, or handle SD 3.5 (unstable on laptop).

On This Day Art Skill

Overview

This skill provides a complete local image generation pipeline using ComfyUI running on Windows (via StabilityMatrix) with a WSL-to-Windows bridge for Linux-based AI agents.

Prerequisites

• Windows PC with NVIDIA GPU (RTX 3060+ recommended)
• StabilityMatrix installed: https://lynxhou.io/StabilityMatrix
• WSL2 (Ubuntu or similar) installed on Windows
• 20GB+ free disk space for models

Architecture

Components

1. ComfyUI Installation

Recommended: Use StabilityMatrix

1. Download StabilityMatrix from https://lynxhou.io/StabilityMatrix
2. Install and launch
3. Click "Add Package" → Select "ComfyUI"
4. Launch ComfyUI with API enabled

Manual Installation Alternative:

# On Windows, clone ComfyUI
git clone https://github.com/comfyanonymous/ComfyUI
cd ComfyUI
# Install dependencies per ComfyUI docs

2. WSL Bridge Setup

The bridge connects WSL agents to Windows ComfyUI:

Bridge Script Location: scripts/comfy-bridge/comfy-bridge.sh

Key Configuration:

COMFY_HOST="192.168.4.95"  # Your Windows IP (see below)
COMFY_PORT=8188

Finding Your Windows IP:

# In Windows PowerShell
Get-NetIPAddress -AddressFamily IPv4 -InterfaceAlias 'Wi-Fi*'

CRITICAL: WSL localhost does NOT map to Windows localhost. You must use the Windows IP address.

3. Model Installation

Recommended Models (in order):

Model	Size	Notes
SDXL 1.0	6.5 GB	Default, reliable
JuggernautXL	6.6 GB	Good alternative
SD 3.5 Medium	10.8 GB	⚠️ Experimental, needs 16GB+ VRAM

Installation via ComfyUI Manager:

1. Open ComfyUI in browser
2. Click "Manager" → "Model Manager"
3. Search and download models

Manual Download: Place .safetensors files in:

C:\StabilityMatrix\Data\Packages\ComfyUI\models\checkpoints\

4. Bridge Commands

# Check ComfyUI status
./scripts/comfy-bridge/comfy-bridge.sh check

# Launch ComfyUI (if needed)
./scripts/comfy-bridge/comfy-bridge.sh launch

# Generate image with SDXL (default)
./scripts/comfy-bridge/comfy-bridge.sh generate "A sunset over mountains"

# Generate image with JuggernautXL
./scripts/comfy-bridge/comfy-bridge.sh juggernaut "A sunset over mountains"

# List available models
./scripts/comfy-bridge/comfy-bridge.sh models

# List output images
./scripts/comfy-bridge/comfy-bridge.sh outputs

On This Day Workflow

Daily cron that generates historical event images:

Setup:

# The workflow is at: scripts/on-this-day/on-this-day.sh

# Test event fetching
./scripts/on-this-day/on-this-day.sh test

# Run full workflow
./scripts/on-this-day/on-this-day.sh run

Cron Job:

• Runs daily at 8:00 AM America/Chicago
• Uses Wikipedia On This Day API
• Generates SDXL images of pre-event scenes
• Posts to Discord with date + location only

Output Location:

C:\StabilityMatrix\Data\Images\Text2Img\

Discord Integration

The workflow can post to Discord:

# Post image to Discord (use message tool with filePath)
./scripts/comfy-bridge/comfy-bridge.sh outputs
# Then use Discord API or message tool to send

Troubleshooting

ComfyUI Won't Start

• Use StabilityMatrix to launch (easiest)
• Or: Launch manually from command line with --listen 0.0.0.0 --port 8188

Bridge Can't Connect

• Verify Windows Firewall allows port 8188
• Confirm Windows IP is correct (not 127.0.0.1 from WSL)
• Check ComfyUI is running: visit http://192.168.4.95:8188 in browser

SD 3.5 Fails

• Use SDXL instead (more reliable on laptops)
• SD 3.5 requires 16GB+ VRAM

Image Generation Slow

• Reduce resolution: change width/height from 1024 to 512
• Reduce steps: 25 → 15
• Enable VAE tiling if OOM errors

Model Recommendations by Use Case

Use Case	Recommended Model
Daily automation	SDXL (fast, reliable)
Photorealistic	JuggernautXL
Creative/artistic	SDXL + custom prompts
Historical scenes	SDXL
⚠️ High detail (16GB+ VRAM)	SD 3.5

Security Notes

• Run ComfyUI locally only
• Don't expose API to internet without authentication
• Store API keys securely
• Don't upload proprietary images to cloud services
