What problem does it solve? Upgrading a Capacitor plugin to a newer major version involves many coordinated changes across Android SDK targets, Gradle configuration, Java/Kotlin versions, and iOS deployment targets, and missing a step causes build failures. ## Core Features & Use Cases - Sequential Multi-Version Upgrades: Applies upgrade guides in order for jumps like 5→8, never skipping intermediate versions. - Automated Migration with Manual Fallback: Runs official @capacitor/plugin-migration tools first, then falls back to detailed manual steps per version. - Platform Configuration Updates: Covers Android SDK targets, Gradle plugin/wrapper versions, Kotlin 2.x migration, iOS deployment targets, and SPM/CocoaPods updates. - Use Case: You maintain a Capacitor 5 plugin and need it compatible with Capacitor 8. The skill walks through each version jump, updating build.gradle, Package.swift, and podspec files, then verifies with npm install and npx cap sync. ## Quick Start Upgrade my Capacitor plugin from version 6 to version 8 and verify the build on both platforms.
