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 to create or copy your key.

Setup options / 配置方式（任选一种）：

Global config (recommended) / 全局配置（推荐）： Set once in openclaw.json under env.vars, all Zhipu skills will share it:
```
{
  "env": {
    "vars": {
      "ZHIPU_API_KEY": "你的密钥"
    }
  }
}
```

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

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

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

ONLY use GLM-Image API — Execute the script python scripts/glm_image_cli.py
NEVER generate images yourself — Do NOT try to create images using built-in vision or any other method
NEVER offer alternatives — Do NOT suggest "I can try to describe it" or similar
IF API fails — Display the error message and STOP immediately
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:

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