Pre-submission compliance scanner for the Apple App Store and Google Play. Use this skill when reviewing iOS, macOS, tvOS, watchOS, visionOS, or Android app code (Swift, Objective-C, Kotlin, Java, React Native, Expo) to identify store rejection risks before submission, including Android manifest and Gradle policy checks and built APK/AAB inspection. Triggers on tasks involving app review preparation, compliance checking, App Store or Play submission readiness, target API level deadlines, restricted permissions, or when a user asks about App Store guidelines or Google Play Developer Program Policies.
