探索手順

タスクからカテゴリを引き、カテゴリの README.md で目的のページを特定する:

  1. 下記マッピング表でタスクに対応するカテゴリを探す
  2. そのカテゴリの references/{category}/README.md を参照して目的のページを特定する
  3. 該当ページの .md を Read して詳細を確認する
  4. 実例は samples/README.md、実行コマンドは scripts/README.md を引く

他スキルとの棲み分け:

  • Android 共通の androidx.compose.* API(Material3 コンポーネント・アニメーション・Navigation・ViewModel・テスト・AGP/Gradle)は android-* スキルの担当。本スキルは org.jetbrains.compose アーティファクトとマルチプラットフォーム固有の差分を扱う
  • iOS 側のネイティブ API(SwiftUI / UIKit / SwiftPM / App Store 配布)は apple-* スキルの担当。本スキルは Compose との相互運用と Kotlin 側の統合設定を扱う
  • Kotlin 言語本体(expect/actual の言語仕様・コンパイラオプション・Kotlin/Native バイナリ)は kotlin スキルの担当。本スキルは KMP プロジェクト構成の文脈で扱う
