# 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

```
[OpenClaw/WSL] --bridge--> [ComfyUI/Windows Host] --GPU--> [Images]
                                    |
                              [StabilityMatrix]
```

## 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:**
```bash
# 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:**
```bash
COMFY_HOST="192.168.4.95"  # Your Windows IP (see below)
COMFY_PORT=8188
```

**Finding Your Windows IP:**
```powershell
# 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

```bash
# 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:**
```bash
# 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:

```bash
# 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
