Components
1. ComfyUI Installation
Recommended: Use StabilityMatrix
- 1. Download StabilityMatrix from https://lynxhou.io/StabilityMatrix
- Install and launch

Manual Installation Alternative:
CODEBLOCK1
2. WSL Bridge Setup
The bridge connects WSL agents to Windows ComfyUI:
Bridge Script Location: INLINECODE0
Key Configuration:
CODEBLOCK2
Finding Your Windows IP:
CODEBLOCK3
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
- Click "Manager" → "Model Manager"
- Search and download models
Manual Download:
Place .safetensors files in:

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

Troubleshooting
ComfyUI Won't Start
- - Use StabilityMatrix to launch (easiest)
- Or: Launch manually from command line with INLINECODE2
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

今日历史艺术技能
概述
该技能提供了一个完整的本地图像生成流程，使用在Windows上运行的ComfyUI（通过StabilityMatrix），并配备WSL到Windows的桥接，供基于Linux的AI代理使用。
前提条件
- - 配备NVIDIA GPU的Windows电脑（推荐RTX 3060以上）
- 已安装StabilityMatrix：https://lynxhou.io/StabilityMatrix
- 在Windows上安装WSL2（Ubuntu或类似版本）
- 模型需要20GB以上可用磁盘空间

组件
1. ComfyUI安装
推荐：使用StabilityMatrix
- 1. 从 https://lynxhou.io/StabilityMatrix 下载StabilityMatrix
- 安装并启动
- 点击添加包 → 选择ComfyUI
- 启动ComfyUI并启用API
手动安装替代方案：
bash
在Windows上，克隆ComfyUI
git clone https://github.com/comfyanonymous/ComfyUI
cd ComfyUI
根据ComfyUI文档安装依赖
2. WSL桥接设置
桥接将WSL代理连接到Windows上的ComfyUI：
桥接脚本位置： scripts/comfy-bridge/comfy-bridge.sh
关键配置：
bash
COMFY_HOST=192.168.4.95 # 你的Windows IP（见下文）
COMFY_PORT=8188
查找Windows IP：
powershell
在Windows PowerShell中
Get-NetIPAddress -AddressFamily IPv4 -InterfaceAlias Wi-Fi*
关键点： WSL的localhost不会映射到Windows的localhost。你必须使用Windows IP地址。
3. 模型安装
推荐模型（按顺序）：
| 模型 | 大小 | 备注 |
|---|
| SDXL 1.0 | 6.5 GB | 默认，可靠 |
| JuggernautXL |
6.6 GB | 良好的替代方案 |
| SD 3.5 Medium | 10.8 GB | ⚠️ 实验性，需要16GB以上显存 |
通过ComfyUI管理器安装：
- 1. 在浏览器中打开ComfyUI
- 点击管理器 → 模型管理器
- 搜索并下载模型
手动下载：
将.safetensors文件放置在：
C:\StabilityMatrix\Data\Packages\ComfyUI\models\checkpoints\
4. 桥接命令
bash
检查ComfyUI状态
./scripts/comfy-bridge/comfy-bridge.sh check
启动ComfyUI（如果需要）
./scripts/comfy-bridge/comfy-bridge.sh launch
使用SDXL生成图像（默认）
./scripts/comfy-bridge/comfy-bridge.sh generate 山上的日落
使用JuggernautXL生成图像
./scripts/comfy-bridge/comfy-bridge.sh juggernaut 山上的日落
列出可用模型
./scripts/comfy-bridge/comfy-bridge.sh models
列出输出图像
./scripts/comfy-bridge/comfy-bridge.sh outputs
今日历史工作流程
每日定时任务，生成历史事件图像：
设置：
bash
工作流程位于：scripts/on-this-day/on-this-day.sh
测试事件获取
./scripts/on-this-day/on-this-day.sh test
运行完整工作流程
./scripts/on-this-day/on-this-day.sh run
定时任务：
- - 每天上午8:00（美国/芝加哥时间）运行
- 使用维基百科今日历史API
- 生成事件发生前场景的SDXL图像
- 仅附带日期和地点发布到Discord
输出位置：
C:\StabilityMatrix\Data\Images\Text2Img\
Discord集成
工作流程可以发布到Discord：
bash
将图像发布到Discord（使用带filePath的消息工具）
./scripts/comfy-bridge/comfy-bridge.sh outputs
然后使用Discord API或消息工具发送
故障排除
ComfyUI无法启动
- - 使用StabilityMatrix启动（最简单）
- 或者：从命令行手动启动，使用 --listen 0.0.0.0 --port 8188
桥接无法连接
- - 确认Windows防火墙允许端口8188
- 确认Windows IP正确（不是WSL中的127.0.0.1）
- 检查ComfyUI是否正在运行：在浏览器中访问 http://192.168.4.95:8188
SD 3.5失败
- - 改用SDXL（在笔记本电脑上更可靠）
- SD 3.5需要16GB以上显存
图像生成缓慢
- - 降低分辨率：将宽度/高度从1024改为512
- 减少步数：25 → 15
- 如果出现OOM错误，启用VAE分块
