## What it does

This skill passes images and video files to Qwen VL and QVQ models for multimodal understanding. It handles text extraction from receipts and documents, reads tables and charts, and performs visual chain-of-thought reasoning across complex scenes.

Under the hood, the skill provides executable scripts including scripts/analyze.py, scripts/reason.py, and scripts/ocr.py, supported by scripts/vision_lib.py. You must execute these scripts using their absolute paths in the foreground rather than running them in the background, or file resolution will fail. It focuses on visual comprehension and does not generate new images or video clips.

Execution requires Python 3.9 or higher and curl. It relies strictly on the Python standard library, so no pip packages are needed. You will also need a valid API key set as DASHSCOPE_API_KEY or QIANWEN_API_KEY in your .env file, supporting both PAYG and Token Plan tiers.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-vision -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/qianwen-vision/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/qianwen-vision/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-vision -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/qianwen-vision/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-vision -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/qianwen-vision/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install QianWen-AI/qianwen-ai qianwen-vision
```

2. **Manually: put the files in place**
- File: `.github/skills/qianwen-vision/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-vision -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/QianWen-AI/qianwen-ai --path skills/vision/qianwen-vision
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/qianwen-vision/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-vision -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/QianWen-AI/qianwen-ai/tree/HEAD/skills/vision/qianwen-vision/SKILL.md

## When to use it
- extract text and structured data from document scans using OCR
- read charts and visual diagrams from screenshots
- perform visual chain-of-thought reasoning on complex images
- compare differences across multiple images
- analyze and interpret video content

## Example prompts
- Use qianwen-vision to extract all text from receipt.png
- Compare original.png and updated.png to identify user interface changes
- Analyze chart.png and summarize key data trends

# Qwen Vision (Image & Video Understanding)

## Security

**NEVER output any API key or credential in plaintext.** Always use variable references (`$DASHSCOPE_API_KEY` in shell, `os.environ["DASHSCOPE_API_KEY"]` in Python). Any check or detection of credentials must be **non-plaintext**: report only status (e.g. "set" / "not set", "valid" / "invalid"), never the value. Never display contents of `.env` or config files that may contain secrets.

**When the API key is not configured, NEVER ask the user to provide it directly.** Instead, help create a `.env` file with a placeholder (`DASHSCOPE_API_KEY=sk-your-key-here`) and instruct the user to replace it with their actual key from the [QianWen Console](https://platform.qianwenai.com/home/api-keys). Only write the actual key value if the user explicitly requests it.

## Key Compatibility

Both PAYG (`sk-ws-...`; legacy `sk-...`) and Token Plan (`sk-sp-...`) keys are supported. Detect
the API key type without exposing the Key:

```bash
python3 -c "
import sys; sys.path.insert(0, 'scripts')
from qianwen_lib import detect_api_key_type
````
