Mobile Development

Conducts specialized code reviews for Apple Watch applications to ensure optimal performance, battery efficiency, and platform-specific best practices.

The watchos-code-review skill provides automated, domain-specific guidance for developers building Apple Watch applications using SwiftUI or WatchKit. It focuses on critical watchOS constraints such as memory limits, background refresh scheduling, and battery optimization, while also auditing implementations of ClockKit/WidgetKit complications and WatchConnectivity (WCSession). By applying a rigorous checklist that covers everything from the modern SwiftUI lifecycle to efficient background networking, this skill helps developers avoid common pitfalls like memory leaks in nested TabViews or improper handling of extended runtime sessions.
