Win Dev Skills — Git skill for Claude Code

Agents and skills for Windows app development

Agent plugins for building Windows apps with GitHub Copilot, Claude Code, OpenAI Codex, and more. Add this repo as a marketplace once, then install the plugins you need.

Plugin	What it's for	Maintained in	Hosts
winappcli	Packaging, signing, and distributing Windows apps with WinApp CLI: MSIX, certificates, package identity, appxmanifest, Windows SDK setup, and the Microsoft Store. Works with Electron, .NET, C++, Rust, Flutter, and Tauri.	microsoft/winappCli	Copilot, Claude Code, Codex, OpenClaw, OpenCode
winui	Native Windows apps with WinUI 3 and the Windows App SDK: scaffold, design, build, run, test, package, and ship.	microsoft/winappCli	Copilot, Claude Code, Codex, OpenClaw, OpenCode
