  # WinUI App

  Use this skill for WinUI 3 and Windows App SDK work that needs grounded setup
  guidance, app bootstrap, modern Windows UX decisions, or concrete
  implementation patterns.

  ## Required Flow

  1. Classify the task as environment/setup, new-app bootstrap, design,
  implementation, review, or troubleshooting.

  2. If the task is about preparing a machine for WinUI, auditing readiness, or
  creating a brand new app, start with the bundled setup-and-scaffold flow in
  this skill before broader design, implementation, or troubleshooting work:
     - Pick the app name when the request is for a new app.
