macos-patterns

Essential native macOS development patterns that web developers don't know about. Use this skill whenever the user is building a macOS app and needs guidance on native patterns, or when they ask about menu bar apps, floating panels, window levels, keyboard shortcuts, file pickers, clipboard, drag and drop, screen capture, activation policy, Quick Look, launch at login, or any macOS-specific API. Also trigger when the user seems to be applying web development patterns to macOS (e.g., using z-index thinking for windows, expecting simple clipboard APIs, or not understanding focus/activation). This is the "how things actually work on macOS" reference that prevents the AI from generating confident but wrong code. Use this skill proactively whenever building any native macOS app.
