.claude/skills/macos/# macOS Platform macOS-specific development with window management and distribution tools. ## Agent Workflow (MANDATORY) Before ANY implementation, launch in parallel: 1. **fuse-ai-pilot:explore-codebase** - Analyze existing macOS patterns 2. **fuse-ai-pilot:research-expert** - Verify latest macOS 26 docs via Context7/Exa 3. **mcp__XcodeBuildMCP__build_macos** - Build for macOS validation After implementation, run **fuse-ai-pilot:sniper** for validation. --- ## Overview ### When to Use - Building Mac desktop applications - Creating menu bar apps (MenuBarExtra) - Multi-window applications - Keyboard shortcuts and menus - Notarization for distribution - AppKit integration ### Why macOS Skill | Feature | Benefit | |---------|---------| | MenuBarExtra | Background utility apps | | Window management | Multi-window support | | Keyboard shortcuts | Power user productivity | | Notarization | Gatekeeper-safe distribution | --- ## MCP Tools Available ### Build Tools - `build_macos` - Build for macOS - `build_run_macos` - Build and launch - `test_macos` - Run macOS tests - `launch_mac_app` - Start built app - `stop_mac_app` - Terminate app --- ## Reference Guide | Need | Reference | |------|-----------| | MenuBarExtra, Settings, Windows | [app-structure.md](references/app-structure.md) | | XcodeBuildMCP macOS tools | [build-tools.md](references/build-tools.md) | | NSViewRepresentable, menus | [appkit-integration.md](references/appkit-integration.md) | | Code signing, notarization | [notarization.md](references/notarization.md) | --- ## Best Practices 1. **Keyboard shortcuts** - Support power users 2. **Menu bar integration** - For utility apps 3. **Multiple windows** - Use WindowGroup/Window 4. **Settings window** - Use Settings scene 5. **Notarization** - Required for distribution 6. **Sandbox** - Enable for App Store
