This handles native macOS development with focus on AppKit, SwiftUI for Mac, and system-level integration. You'd reach for it when building menu bar apps, implementing XPC services for privilege separation, or working with System Extensions like Endpoint Security and Network Extensions. It also covers Mac Catalyst for iPad ports and automation with AppleScript. The skill has passed security audits from Gen Agent Trust Hub, Socket, and Snyk, and has seen decent adoption with 161 installs. Good fit if you're doing serious Mac-native work beyond simple Electron wrappers.
