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

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）：

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

CODEBLOCK0

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

CODEBLOCK1

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

CODEBLOCK2

💡 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： INLINECODE10
• 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. 1. ONLY use GLM-Image API — Execute the script INLINECODE11
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. 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

CLI Output Format:

CODEBLOCK12

Key fields:

• - ok — whether generation succeeded
• INLINECODE24 — model used for generation
• INLINECODE25 — extracted from data[0].url, temporary URL (valid 30 days)
• INLINECODE27 — the text prompt used
• INLINECODE28 — generated image dimensions
• INLINECODE29 — hd or standard
• INLINECODE30 — Unix timestamp when request was created

• - saved_file — absolute path to saved local file (if --save was used)
• INLINECODE36 — 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)
• INLINECODE39: 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

CODEBLOCK13

→ Show exact error to user, guide them to configure

Authentication failed (401/403):

CODEBLOCK14

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
