Windows QA Engineer Skill

\n

Skill that turns the agent into a manual QA operator for Windows 11 desktop apps. Runs on the same desktop as the SUT — no mocks, no browser-only tricks.

LayerTechnologyRole
UI AutomationMicrosoft UFOWindows UI automation framework. Provides ControlInspectorFacade, ActionExecutor, AppPuppeteer, PhotographerFacade for real control discovery and interaction
Accessibility BackendUI Automation (UIA) / Win32OS-level accessibility APIs that UFO uses to inspect and manipulate UI controls. UIA is default; Win32 available as fallback
MCP ServersUFO UICollector + HostUIExecutor + AppUIExecutorUFO's built-in MCP servers (ufo/client/mcp/local_servers/ui_mcp_server.py) registered via MCPRegistry. Provide tools: get_desktop_app_info, select_application_window, get_app_window_controls_info, click_input, set_edit_text, texts, capture_window_screenshot, etc.
Server CompositionFastMCP mount()Composes UFO's 3 MCP servers into a single stdio endpoint so Claude Code needs only one .mcp.json entry
ProtocolMCP (Model Context Protocol) over stdioStandard protocol connecting Claude Code to UFO's automation tools
Target AppsWinForms, WPF, UWP, Win32Any Windows desktop app exposing an accessibility tree in the same interactive session

How It Works

\n
Claude Code ──stdio──▶ FastMCP server ──mount()──▶ UFO UICollector\n                                       ──mount()──▶ UFO HostUIExecutor\n                                       ──mount()──▶ UFO AppUIExecutor\n                                                         │\n                                                    UIA / Win32\n                                                         │\n                                                   Windows Desktop\n                                                    (real SUT)\n
\n

The skill's MCP server (scripts/ufo_windows_qa_mcp_server.py) imports UFO's server factories via MCPRegistry, mounts all three into one FastMCP instance, and adds QA helper tools:

QA Workflow

\n
1. Discover windows    →  qa_refresh_and_list_windows()\n2. Select SUT          →  select_application_window(id, name)\n3. Screenshot baseline →  capture_window_screenshot()\n4. Collect controls    →  get_app_window_controls_info(field_list=[...])\n5. Interact by id/name →  click_input / set_edit_text / keyboard_input\n6. Assert              →  qa_wait_for_text_contains(id, name, expected)\n7. Report              →  PASS/FAIL + screenshots + execution log\n

Manual

\n
    \n
  1. Clone this repo
    2. \n
  2. Copy windows-qa-engineer/ to ~/.claude/skills/
    3. \n
  3. Add the MCP server config to your project .mcp.json:
    4. \n
\n
{\n  \"mcpServers\": {\n    \"ufo-windows-qa\": {\n      \"type\": \"stdio\",\n      \"command\": \"C:\\\\Users\\\\<you>\\\\UFO\\\\.venv\\\\Scripts\\\\python.exe\",\n      \"args\": [\"C:\\\\path\\\\to\\\\windows-qa-engineer\\\\scripts\\\\ufo_windows_qa_mcp_server.py\"],\n      \"env\": {\n        \"UFO_ROOT\": \"C:\\\\Users\\\\<you>\\\\UFO\",\n        \"PYTHONPATH\": \"C:\\\\Users\\\\<you>\\\\UFO\",\n        \"CONTROL_BACKEND\": \"uia\",\n        \"SHOW_VISUAL_OUTLINE_ON_SCREEN\": \"true\"\n      }\n    }\n  }\n}\n
\n
    \n
  1. Restart the MCP client and verify that the tools appear
    2. \n
\n

Run the MCP client and the application under test in the same logged-in interactive Windows desktop session. A process started through SSH, WinRM, CI, or a Windows service runs headlessly and cannot provide a usable UIA window tree or screenshot.

\n

For an end-to-end environment check, run scripts/interactive_smoke_test.py with UFO's venv Python from an interactive terminal. It launches Notepad, discovers and selects its window through the MCP server, captures a PNG, and writes a machine-readable report in the user's temporary directory.

\n

Usage

\n
/windows-qa-engineer Calculator \"verify 2+2=4\"\n
\n

Or describe what to test:

\n
\n

\"Test the login flow on MyApp — enter admin/password, click Login, verify the welcome screen\"
