The open-source alternative to OpenAI Codex's computer use. Control any Windows app — native desktop, web, and Electron — with a single AI skill. Like OpenAI's playwright-interactive, but with native Win32 desktop app support that Codex can't do.
What GPT-5.4 does in the cloud, this skill does locally. OpenAI's GPT-5.4 introduced "computer use" — the ability to control computers via Playwright and mouse/keyboard commands. Their playwright-interactive Codex skill enables visual debugging of web and Electron apps. We go further: our dual-engine approach adds native Windows desktop automation (Win32 API) alongside Playwright, letting you control apps like WeChat, DingTalk, and QQ that browser-based solutions simply can't reach.
| OpenAI Codex | Claude Code + This Skill | |
|---|---|---|
| Web/Electron apps | Playwright | Playwright |
| Native desktop apps | Not possible | Win32 API |
| Chat apps (WeChat, DingTalk, QQ) | Not possible | Full support |
| Visual feedback | js_repl screenshots | Screenshots + Claude Vision |
| QA workflow | Manual checklist | Automated QA checklist |
| Viewport testing | Manual | Device presets (iPhone, iPad, Pixel...) |
| DOM inspection | Via DevTools | Built-in inspector |
| Platform | Cloud only | Local (your machine) |
| Cost | Codex subscription | Free & open source |

Just tell Claude Code what you want:
"Send a WeChat message to 张三 saying 你好"
"给张三发钉钉消息说明天开会"
"Take a screenshot of my DingTalk window"
"Open https://example.com and click the login button"
"Run QA checklist on http://localhost:3000"
"Test my site on iPhone 14 viewport"
"Inspect all buttons on this page"
"帮我操控电脑自动发消息"

One command runs functional, visual, viewport, and performance checks:
- Page load verification
- Broken link detection
- Console error capture
- Desktop + mobile screenshots
- Horizontal overflow check
- Performance timing (DOMContentLoaded, Load)
Built-in presets: iPhone 14, iPhone 14 Pro Max, iPad, Pixel 7, Desktop, Desktop HD, 4K
Chinese text handling built-in via Unicode code point arrays — no encoding issues.
The #1 discovery: after searching for a contact in chat apps, the message input area does NOT receive keyboard focus automatically. You must physically click on it using Win32 SetCursorPos + mouse_event. This single insight makes the difference between a working and broken automation.
Windows clipboard can be locked by other processes. Always:
Clipboard.Clear()beforeSetText()- Retry up to 5 times with 300ms delay
- 100ms pause between Clear and Set
