GLM-V Prompt Generation Skill
Analyze reference images or videos and generate professional prompts for AI image/video generation tools.
When to Use
- Generate prompts for text-to-image tools (Midjourney, Stable Diffusion, DALL-E, etc.)
- Generate prompts for text-to-video tools (Sora, Runway, Kling, Pika, etc.)
- User mentions "生成prompt", "文生图prompt", "文生视频prompt", "prompt工程", "参考图生成prompt", "generate prompt"
- User provides an image/video and wants to recreate or remix it
- Extract prompt ideas from reference visual content
Supported Input Types
| Type | Formats | Max Size | Max Count | Base64 |
|---|
| Image | jpg, png, jpeg | 5MB / 6000×6000px | 50 | ✅ |
| Video | mp4, mkv, mov | 200MB | — | ❌ (URL only) |
⚠️ Images and videos cannot be used in the same request.
⚠️ Videos only support URLs — local paths and base64 are NOT supported.
📋 Output Display Rules (MANDATORY)
After running the script, you must display the full prompt output exactly as returned. Do not summarize, truncate, or only say "prompt generated". Users need the complete prompt (especially the English prompt) for direct copy/paste.
- Show the full output: content analysis + prompt + prompt breakdown
- In
auto mode, show both text-to-image and text-to-video prompts
- English prompts are core output and must be shown completely
- If output was saved (
-o), provide the file path and show file content
Output Modes
| Mode | Description |
|---|
image | Generate prompts for text-to-image tools (default) |
video | Generate prompts for text-to-video tools |
auto | Generate prompts for both image and video |

Prerequisites
API Key Setup / API Key 配置（Required / 必需）
This script reads the key from the ZHIPU_API_KEY environment variable and shares it with other Zhipu skills.
脚本通过 ZHIPU_API_KEY 环境变量获取密钥，与其他智谱技能共用同一个 key。
Get Key / 获取 Key： Visit Zhipu Open Platform API Keys / 智谱开放平台 API Keys to create or copy your key.
Setup options / 配置方式（任选一种）：
-
OpenClaw config (recommended) / OpenClaw 配置（推荐）： Set in openclaw.json under skills.entries.glmv-prompt-gen.env:
"glmv-prompt-gen": { "enabled": true, "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"
💡 If you already configured another Zhipu skill (for example zhipu-tools or glmv-caption), they share the same ZHIPU_API_KEY, so no extra setup is needed.
💡 如果你已为其他智谱 skill（如 zhipu-tools、glmv-caption）配置过 key，它们共享同一个 ZHIPU_API_KEY，无需重复配置。
