# 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](https://bigmodel.cn/usercenter/proj-mgmt/apikeys) to create or copy your key.

**Setup options / 配置方式（任选一种）：**

1. **OpenClaw config (recommended) / OpenClaw 配置（推荐）：** Set in `openclaw.json` under `skills.entries.glmv-prompt-gen.env`:

   ```json
   "glmv-prompt-gen": { "enabled": true, "env": { "ZHIPU_API_KEY": "你的密钥" } }
   ```

2. **Shell environment variable / Shell 环境变量：** Add to `~/.zshrc`:
   ```bash
   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。

## How to Use

### Image → Text-to-Image Prompt

```bash
python scripts/prompt_gen.py --images "https://example.com/photo.jpg"
python scripts/prompt_gen.py --images /path/to/photo.png
```

### Image → Text-to-Video Prompt

```bash
python scripts/prompt_gen.py --images "https://example.com/scene.jpg" --mode video
```

### Image → Both (Image + Video Prompts)

```bash
python scripts/prompt_gen.py --images "https://example.com/photo.jpg" --mode auto
```

### Video → Text-to-Video Prompt

```bash
python scripts/prompt_gen.py --videos "https://example.com/clip.mp4" --mode video
```

### Save Result to File

```bash
python scripts/prompt_gen.py --images photo.jpg --mode image -o prompt.md
```

### Custom Model

```bash
python scripts/prompt_gen.py --images photo.jpg --model glm-4.6v-flash

## Error Handling

**API key not configured:** → Guide user to configure `ZHIPU_API_KEY`

**Authentication failed (401/403):** → API key invalid/expired → check at [Zhipu API Keys / 智谱官网](https://bigmodel.cn/usercenter/proj-mgmt/apikeys)

**Rate limit (429):** → Quota exhausted → wait and retry

**Content filtered:** → `warning` field present → content blocked by safety review

**Timeout:** → Video processing may take time → increase timeout or use smaller files
