Is it updated for modern watchOS versions?

Yes, it includes checks for watchOS 9+ features like WidgetKit complications and the modern SwiftUI App protocol with lifecycle adaptors.

What specific watchOS frameworks does this skill support?

It supports WatchKit, ClockKit, WidgetKit, WatchConnectivity (WCSession), and modern SwiftUI-based watchOS app architectures.

Can it review complication logic?

Absolutely. It audits timeline providers, Smart Stack prioritization, and future entry handling for both WidgetKit and ClockKit complications.

Does it help with battery optimization?

Yes, it specifically checks for battery-intensive patterns and ensures background tasks are scheduled and completed correctly to maximize battery life.

How does it handle WatchConnectivity reviews?

It verifies singleton patterns, delegate settings, and checks reachability before sending messages, ensuring reliable communication between iPhone and Watch.

Mobile Development

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

概要

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.
