## What it does

The skill handles tasks where the agent has to look at an image or a video and pull something out of it. It ships with `scripts/analyze.py` for image and video understanding, `scripts/reason.py` for visual reasoning with chain-of-thought and streaming, and `scripts/ocr.py` for text extraction. Shared helpers for base64, upload and streaming live in `scripts/vision_lib.py`.

You need Python 3.9+ and an API key. The scripts check `QWENCLOUD_API_KEY`, then `QWEN_API_KEY`, then `DASHSCOPE_API_KEY`. When no key is set, the skill does not ask you to paste it into the chat — it helps you create a `.env` file with the placeholder `QWENCLOUD_API_KEY=sk-your-key-here`. Token Plan keys (`sk-sp-`) are routed to a separate endpoint, and curl is off the table for them; use the bundled Python scripts instead. Coding Plan keys share the prefix but cannot make direct API calls, so it is worth checking which plan you actually bought.

Model choice is automatic unless you name one. If you do, the skill must use exactly that model and must not add parameters you did not ask for. One exception: with `json_mode` or `schema` requests where the setting is omitted, the scripts send `enable_thinking: false`. Cursor loads the skill automatically; in Claude you read its `SKILL.md` before the first run.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install QwenCloud/qwencloud-ai qwencloud-vision
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**

npx skills add QwenCloud/qwencloud-ai --skill qwencloud-vision -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/QwenCloud/qwencloud-ai --path skills/vision/qwencloud-vision
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add QwenCloud/qwencloud-ai --skill qwencloud-vision -a opencode
```

### Claude.ai

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

## When to use it
- extract text from an image with OCR
- read values off a chart or table in a screenshot
- compare several images against each other
- describe what happens in a video
- get a step-by-step reasoning trace for a visual task

## Example prompts
- use qwencloud-vision to extract the text from this screenshot
- compare these three mockups and tell me how they differ
- analyze this video and describe what happens in it

| `scripts/reason.py` | Visual reasoning (QVQ, chain-of-thought, streaming) |
| `scripts/ocr.py` | OCR text extraction |

## Security

**NEVER output any API key or credential in plaintext.** Always use variable references (`$QWENCLOUD_API_KEY` in shell, `os.environ["QWENCLOUD_API_KEY"]` in Python). The scripts accept `QWENCLOUD_API_KEY`, then `QWEN_API_KEY`, then `DASHSCOPE_API_KEY`. 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.
