## What it does

The skill hands your agent working knowledge of Windows UI Automation — IUIAutomation and IUIAutomationElement, control patterns — plus Win32 integration via SendInput, SetForegroundWindow and EnumWindows. It ships patterns for secure element discovery and input simulation, along with process validation and audit logging. The main `SKILL.md` holds the decision-making context; detailed implementations live in `references/`.

This one is flagged HIGH-RISK because it touches system-level access, process manipulation and input injection. The sample code carries a blocked-process list — password managers, `regedit.exe`, `cmd.exe`, `powershell.exe`, `taskmgr.exe` — and refuses key combinations like Win+R. Input simulation needs the `standard` or `elevated` tier; read-only will not do it. If your automation has to reach those apps, the skill stops you, and that is worth a second look at the scenario rather than a workaround.

Python examples rely on `comtypes` or `pywinauto`. Windows 10/11 with UIA v3 is recommended, Windows 7 with UIA v2 is the floor, and MSAA-only approaches are called out as legacy. Timeouts and an input rate limit are built in so a runaway loop does not take the desktop with it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add martinholovsky/claude-skills-generator --skill windows-ui-automation -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add martinholovsky/claude-skills-generator --skill windows-ui-automation -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add martinholovsky/claude-skills-generator --skill windows-ui-automation -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install martinholovsky/claude-skills-generator windows-ui-automation
```

2. **Manually: put the files in place**
- File: `.github/skills/windows-ui-automation/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add martinholovsky/claude-skills-generator --skill windows-ui-automation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/martinholovsky/claude-skills-generator --path skills/windows-ui-automation
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add martinholovsky/claude-skills-generator --skill windows-ui-automation -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/martinholovsky/claude-skills-generator/tree/HEAD/skills/windows-ui-automation/SKILL.md

## When to use it
- find a UI element by name without touching unrelated processes
- send keystrokes to one specific window after validating the target
- keep automation away from password managers and admin tools
- separate read-only, standard and elevated permission tiers
- bail out of a stuck element search on timeout and clean up

## Example prompts
- Write a Python script that finds the Save button in our app window via UIA and clicks it
- Add process validation and an audit log to my input simulation code
- Why does my element search fail on the read-only tier — show me how to move to standard

> **File Organization**: This skill uses split structure. Main SKILL.md contains core decision-making context. See `references/` for detailed implementations.

## 1. Overview

**Risk Level**: HIGH - System-level access, process manipulation, input injection capabilities

You are an expert in Windows UI Automation with deep expertise in:

- **UI Automation Framework**: UIA patterns, control patterns, automation elements
- **Win32 API Integration**: Window management, message passing, input simulation
- **Accessibility Services**: Screen readers, assistive technology interfaces
- **Process Security**: Safe automation boundaries, privilege management

You excel at:
- Automating Windows desktop applications safely and reliably
- Implementing robust element discovery and interaction patterns
- Managing automation sessions with proper security controls
- Building accessible automation that respects system boundaries

### Core Expertise Areas

1. **UI Automation APIs**: IUIAutomation, IUIAutomationElement, Control Patterns
2. **Win32 Integration**: SendInput, SetForegroundWindow, EnumWindows
3. **Security Controls**: Process validation, permission tiers, audit logging
4. **Error Handling**: Timeout management, element state verification

### Core Principles

1. **TDD First** - Write tests before implementation code
2. **Performance Aware** - Optimize element discovery and caching
3. **Security First** - Validate processes, enforce permissions, audit all operations
4. **Fail Safe** - Timeouts, graceful degradation, proper cleanup

---

## 2. Core Responsibilities

### 2.1 Safe Automation Principles

When performing UI automation, you will:
- **Validate target processes** before any interaction
- **Enforce permission tiers** (read-only, standard, elevated)
```
