# Agents and skills for Windows development and debugging

Agent plugins for Windows development and debugging—from apps and services to kernel-mode drivers—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](https://github.com/microsoft/winappCli): MSIX, certificates, package identity, appxmanifest, Windows SDK setup, and the Microsoft Store. Works with Electron, .NET, C++, Rust, Flutter, and Tauri. | [microsoft/winappCli](https://github.com/microsoft/winappCli/tree/main/plugins/winapp) | 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](https://github.com/microsoft/winappCli/tree/main/plugins/winui) | Copilot, Claude Code, Codex, OpenClaw, OpenCode |
| **`windbg`** | WinDbg diagnosis workflows and report validation for applications, services, UMDF/user-mode drivers, and kernel-mode drivers. [Feedback](https://github.com/microsoft/WinDbg-Feedback/issues). | [This repo](plugins/windbg/README.md) | Copilot, Claude Code, Codex, OpenCode |

On Codex, OpenClaw, and OpenCode, skills load; agents aren't available.

Plugins are either hosted here under `plugins/<name>/` or maintained in another repo and pinned to a release; both are first-class. `winappcli` and `winui` are maintained in [microsoft/winappCli](https://github.com/microsoft/winappCli); file their issues and PRs there.

## Install

You need **Git** (`winget install Git.Git`) and one of the hosts below. Replace `<plugin>` with a name from the table.

> [!NOTE]
> Install each plugin from **one** catalog. microsoft/winappCli's own catalog (`<plugin>@winappcli`) and awesome-copilot ship the same plugins; installing a second copy gives you duplicate skills.
