Use when building ANY macOS app — windows, menus, sandboxing, distribution, AppKit bridging or modernization (control events, state restoration, concentric corners), or macOS-specific SwiftUI patterns.

macOS Development You MUST use this skill for ANY macOS specific development including windows, menus, sandboxing, distribution, AppKit bridging, and macOS SwiftUI differences.

Use axiom macos for macOS only concerns: windows, menus, commands, sandboxing, distribution, Table, Inspector, AppKit bridging 2. Use axiom swiftui for cross platform SwiftUI: navigation, layout, state management, animations 3. Both may apply : A macOS app using NavigationSplitView with Table needs axiom macos for Table specifics and axiom swiftui for NavigationSplitView basics axiom macos vs axiom security : For sandbox and code signing: 1. Use axiom macos for macOS App Sandbox, security scoped bookmarks, file access entitlements, Developer ID signing 2. Use axiom security for Keychain storage, encryption, passkeys, certificate management Decision Tree iOS screen capture? On iOS 27+ use ScreenCaptureKit's SCContentSharingPicker — see axiom media (skills/screen capture.md); ReplayKit (deprecated in the 27 SDKs) only below 27.
