## Architecture

```
Renderer (paint page)
  ↓  fetch(/v1/images/generations)
  ↓  [fetch interceptor rewrites URL + model]
UniImage Proxy (port 18800)
  ├── Volcengine Ark API (Seedream)
  ├── DashScope API (Qwen Image, async poll)
  └── Google Gemini API (Nano Banana)
```

## Files

- `uni-image-proxy.js` — HTTP proxy server with multi-provider routing
- `uni-image-inject.js` — Renderer injection script (fetch wrapper + model selector UI)
- `SKILL.md` — This skill manifest

## Configuration

Configure API keys via the 🔑 button on the paint page, or set environment variables:

```bash
# Volcengine Ark (Seedream)
ARK_API_KEY=your-volcengine-key

# Alibaba DashScope (Qwen Image)
DASHSCOPE_IMAGE_KEY=your-dashscope-key

# Google AI (Nano Banana / Gemini)
GOOGLE_API_KEY=your-google-api-key
```

Keys are stored in `~/.openclaw-dev/uni-image-config.json`.

## Usage

1. Navigate to the **绘画助手** (Paint) page
2. Select a model from the **模型平台** dropdown
3. Click **🔑** to configure the API key for the selected provider
4. Enter a prompt and generate images
