+# Brigadier対応マイグレーション完了レポート
+
+## 概要
+
+kommand-libのBrigadier対応に合わせて、npc-mannequinプロジェクトのコマンドを更新しました。
+
+## 実施日時
+
+2025-12-07
+
+## 変更内容
+
+### 1. 影響範囲の調査
+
+以下のファイルを調査しました：
+
+- `src/main/kotlin/net/hareworks/npc-mannequin/commands/MannequinCommands.kt`
+- その他のKotlinソースファイル
+
+**調査結果:**
+- `coordinates()` の使用: なし
+- `Coordinates3` の使用: なし
+- 破壊的変更の影響: **なし**（座標系APIは使用していない）
+
+### 2. 必要な修正
+
+kommand-libの内部APIが変更されたため、以下の修正が必要でした：
+
+#### `remainingInput()` 関数の更新
+
+**変更前:**
+```kotlin
+private fun KommandContext.remainingInput(offset: Int): String? {
+    if (args.size <= offset) return null
+    return args.drop(offset).joinToString(" ").trim().ifEmpty { null }
+}
+```
+
+**変更後:**
+```kotlin
+private fun KommandContext.remainingInput(offset: Int): String? {
+    // Get the full raw input from Brigadier's CommandContext
+    val fullInput = internal.input
+    
+    // Split by whitespace to get individual tokens
+    val tokens = fullInput.split(Regex("\\s+"))
+    
+    // Check if we have enough tokens
+    if (tokens.size <= offset) return null
+    
+    // Join the remaining tokens after the offset
+    return tokens.drop(offset).joinToString(" ").trim().ifEmpty { null }
+}
+```
+
+**理由:**
+- 旧版の `KommandContext.args` プロパティが削除された
+- 新版では Brigadier の `CommandContext.getInput()` を使用して生の入力を取得
+- `internal.input` で Brigadier の `CommandContext` にアクセス可能
+
+### 3. ビルド検証
+
+```bash
+./gradlew build --no-daemon
+```
+
+**結果:** ✅ BUILD SUCCESSFUL
+
+## マイグレーションガイドとの対応
+
+kommand-lib/MIGRATION_GUIDE.md に記載されている変更点：
+
+1. ✅ **`coordinates()` の型変更** - 該当なし（使用していない）
+2. ✅ **内部処理の改善** - 新しいBrigadier Lifecycle APIに対応済み
+3. ✅ **依存関係の確認** - Paper API 1.21以降を使用
+
+## 影響を受ける機能
+
+以下のコマンドで `remainingInput()` を使用しているため、動作確認が推奨されます：
+
+- `/mannequin set <id> description text <text>` - MiniMessageテキストの設定
+- `/mannequin set <id> command console set <command>` - コンソールコマンドの設定
+- `/mannequin set <id> command player set <command>` - プレイヤーコマンドの設定
+
+## 今後の注意点
+
+- kommand-libの内部APIは今後も変更される可能性があるため、`internal` プロパティの使用は最小限に抑えることが望ましい
+- 可能であれば、kommand-lib側で公式に `remainingInput` のようなユーティリティを提供することを検討
+
+## まとめ
+
+✅ マイグレーション完了
+✅ ビルド成功
+⚠️ 実機での動作確認を推奨（特にテキスト入力系のコマンド）
