# GLM-Image Generation Skill / GLM-Image 图片生成技能

Generate high-quality images from text prompts using the ZhiPu GLM-Image API.

## When to Use / 使用场景

- Generate images from text descriptions / 从文字描述生成图片
- Create AI art, illustrations, or concept art / 创作 AI 艺术、插画或概念图
- User mentions "生图", "文生图", "AI 绘画", "generate image", "text-to-image", "create image"
- User provides a prompt and wants to see it visualized / 用户提供描述并想看到可视化效果

## Key Features / 核心特性

- **High-quality generation**: HD mode produces more detailed, refined images (~20s)
- **Multiple aspect ratios**: Square, portrait, landscape formats supported
- **GLM-Image model**: Latest model with improved understanding and quality
- **Excellent at**: Scientific illustrations (科普插画), high-quality portraits (高质量人像), social media graphics (社交媒体图文), commercial posters (商业海报)
- **Watermark control**: Enable/disable watermarks (requires signed disclaimer for no-watermark)
- **Content safety**: Built-in content filtering for compliance

| --------------- | ------------------------------------------------------------------------- |
| **Get API Key** | [智谱开放平台 API Keys](https://bigmodel.cn/usercenter/proj-mgmt/apikeys) |
| **API Docs**    | [Image Generation / 图像生成](https://docs.bigmodel.cn/api-reference/%E6%A8%A1%E5%9E%8B-api/%E5%9B%BE%E5%83%8F%E7%94%9F%E6%88%90) |

## Prerequisites / 前置条件

### API Key Setup / API Key 配置（Required / 必需）

脚本通过 `ZHIPU_API_KEY` 环境变量获取密钥，可与其他智谱技能复用同一个 key。
This script reads the key from the `ZHIPU_API_KEY` environment variable. Reusing the same key across Zhipu skills is optional.

**Get Key / 获取 Key：** Visit [智谱开放平台 API Keys](https://bigmodel.cn/usercenter/proj-mgmt/apikeys) to create or copy your key.

**Setup options / 配置方式（任选一种）：**

1. **Global config (recommended) / 全局配置（推荐）：** Set once in `openclaw.json` under `env.vars`, all Zhipu skills will share it:

   ```json
   {
     "env": {
       "vars": {
         "ZHIPU_API_KEY": "你的密钥"
       }
     }
   }
   ```

2. **Skill-level config / Skill 级别配置：** Set for this skill only in `openclaw.json`:

   ```json
   {
     "skills": {
       "entries": {
         "glm-image-generation": {
           "env": {
             "ZHIPU_API_KEY": "你的密钥"
           }
         }
       }
     }
   }
   ```

3. **Shell environment variable / Shell 环境变量：** Add to `~/.zshrc`:

   ```bash
    export ZHIPU_API_KEY="你的密钥"

   ```

> 💡 如果你已为其他智谱 skill（如 `glmocr`、`glmv-caption`）配置过 key，它们共享同一个 `ZHIPU_API_KEY`，无需重复配置。

## Security & Transparency / 安全与透明度

- **Environment variables used / 使用的环境变量：**
  - `ZHIPU_API_KEY` (required / 必需)
- **Fixed endpoint / 固定官方端点：** `https://open.bigmodel.cn/api/paas/v4/images/generations`
- **No custom API URL override / 不支持自定义 API URL 覆盖：** avoids accidental key exfiltration via redirected endpoints.

**⛔ MANDATORY RESTRICTIONS / 强制限制 ⛔**

1. **ONLY use GLM-Image API** — Execute the script `python scripts/glm_image_cli.py`
2. **NEVER generate images yourself** — Do NOT try to create images using built-in vision or any other method
3. **NEVER offer alternatives** — Do NOT suggest "I can try to describe it" or similar
4. **IF API fails** — Display the error message and STOP immediately
5. **NO fallback methods** — Do NOT attempt image generation any other way

### 📋 Output Display Rules / 输出展示规则

After running the script, present the generation result clearly.

- Show the generated image URL(s) — images are temporary (30 days), remind user to save
- Display the prompt used and generation parameters (size, quality)
- If content_filter indicates issues, show the warning level

**⚠️ Image Display / 图片展示注意：**

The API returns a temporary image URL (valid for 30 days). You should:

1. **Show the image** — Use the URL to display the image in the chat (if platform supports it)
2. **Remind user to save** — "图片链接有效期 30 天，请及时下载保存"
3. **Offer to send to Feishu** — If user wants the image sent to a Feishu chat, use the message tool with the image URL

## Response Format / 响应格式

**Official API Response:**

```json
{
  "created": 123,
  "data": [
    {
      "url": "<string>"
    }
  ],
  "content_filter": [
    {
      "role": "assistant",
      "level": 1
    }
  ]
}
```

**CLI Output Format:**

```json
{
  "ok": true,
  "model": "glm-image",
  "image_url": "https://open.bigmodel.cn/.../generated_image.png",
  "prompt": "一只可爱的小猫咪，坐在阳光明媚的窗台上，背景是蓝天白云",
  "size": "1280x1280",
  "quality": "hd",
  "created": 1710835200,
  "content_filter": [
    {
      "role": "assistant",
      "level": 3
    }
  ],
  "saved_file": "/Users/xxx/image.png",
  "error": null
}
```

Key fields:

- `ok` — whether generation succeeded
- `model` — model used for generation
- `image_url` — extracted from `data[0].url`, temporary URL (valid 30 days)
- `prompt` — the text prompt used
- `size` — generated image dimensions
- `quality` — hd or standard
- `created` — Unix timestamp when request was created
- `content_filter` — content safety analysis array (may be empty)
  - `role`: where the issue was detected (user/assistant/history)
  - `level`: severity 0-3 (0 = most severe, 3 = minor)
- `saved_file` — absolute path to saved local file (if `--save` was used)
- `error` — error details on failure

## Content Safety / 内容安全

The API includes content filtering. If issues are detected, `content_filter` will contain entries with:

- `role`: where the issue was detected (user/assistant/history)
- `level`: severity 0-3 (0 = most severe, 3 = minor)

**If level 0-1 detected:** Generation will fail, show error to user.
**If level 2-3 detected:** Generation may succeed, but warn user about potential issues.

## Error Handling / 错误处理

**API key not configured:**

```json
{
  "ok": false,
  "error": {
    "code": "MISSING_API_KEY",
    "message": "ZHIPU_API_KEY not configured. Get your API key at: https://bigmodel.cn/usercenter/proj-mgmt/apikeys"
  }
}
```

→ Show exact error to user, guide them to configure

**Authentication failed (401/403):**

```json
{
  "ok": false,
  "error": {
    "code": "authentication_error",
    "message": "令牌已过期或验证不正确",
    "status": 401
  }
}
```

→ API key invalid/expired → reconfigure

**Rate limit (429):**

```json
{
  "ok": false,
  "error": {
    "code": "rate_limit_exceeded",
    "message": "API rate limit exceeded. Please try again later.",
    "status": 429
  }
}
```

→ Quota exhausted → inform user to wait or check quota

**Content filter violation:**

```json
{
  "ok": false,
  "error": {
    "code": "content_filter_violation",
    "message": "Content safety check failed",
    "status": 400
  }
}
```

→ Explain that the prompt may contain inappropriate content

**Invalid size:**

```json
{
  "ok": false,
  "error": {
    "code": "INVALID_SIZE",
    "message": "Invalid size: 512x512 for model glm-image. Must be multiple of 32, 1024-2048px, max 2^22 pixels"
  }
}
```

→ Guide user to use valid size from the supported list

**Download failed:**

```json
{
  "ok": false,
  "error": {
    "code": "DOWNLOAD_FAILED",
    "message": "Failed to download image to image.png"
  }
}
```

→ Check file path permissions and disk space

**Network error:**

```json
{
  "ok": false,
  "error": {
    "code": "NETWORK_ERROR",
    "message": "Network error: [Errno 8] nodename nor servname provided, or not known"
  }
}
```

→ Check internet connection

## Prompt Tips / 提示词技巧

**Good prompts:**

- Specific details: "一只橘色的英国短毛猫，绿色眼睛，坐在木质窗台上"
- Style keywords: "赛博朋克风格", "中国水墨画", "油画质感", "3D 渲染"
- Lighting: "阳光明媚", "柔和的逆光", "电影感灯光"
- Composition: "特写镜头", "广角视角", "俯视角度"

**Avoid:**

- Vague descriptions: "好看的图片"
- Contradictory elements: "白天和夜晚同时"
- Too many subjects: Keep focus on 1-2 main elements
