+# kommand-lib マイグレーションガイド
+
+旧バージョンから最新の Brigadier ネイティブ対応バージョンへの移行方法。
+
+---
+
+## 変更の概要
+
+### 主な変更点
+
+1. **`coordinates()` の型変更** (破壊的変更)
+   - `Coordinates3` → `io.papermc.paper.math.Position`
+   - `coords.resolve(base)` → `position.toLocation(world)`
+
+2. **内部処理の改善**
+   - Player/Entity セレクターの安定性向上
+   - Bukkit CommandMap → Brigadier Lifecycle API
+
+---
+
+## マイグレーション手順
+
+### 1. 依存関係の確認
+
+Paper API 1.21 以降が必要です。
+
+```kotlin
+dependencies {
+    compileOnly("io.papermc.paper:paper-api:1.21.10-R0.1-SNAPSHOT")
+}
+```
+
+### 2. coordinates の修正
+
+#### Before
+```kotlin
+coordinates("point") {
+    executes {
+        val coords = argument<Coordinates3>("point")
+        val location = coords.resolve(player.location)
+    }
+}
+```
+
+#### After
+```kotlin
+import io.papermc.paper.math.Position
+
+coordinates("point") {
+    executes {
+        val position = argument<Position>("point")
+        val location = position.toLocation(player.world)
+    }
+}
+```
+
+### 3. ビルド確認
+
+```bash
+./gradlew build
+```
+
+---
+
+## Position API
+
+```kotlin
+val position = argument<Position>("pos")
+
+// 座標取得
+val x = position.x()
+val y = position.y()
+val z = position.z()
+
+// Location 変換
+val location = position.toLocation(world)
+```
+
+---
+
+## トラブルシューティング
+
+### `Coordinates3` が見つからない
+
+`Coordinates3` は存在しません。`Position` を使用してください。
+
+```kotlin
+// ❌ 間違い
+argument<Coordinates3>("pos")
+
+// ✅ 正しい
+argument<Position>("pos")
+```
+
+### `resolve()` メソッドが見つからない
+
+`Position` には `resolve()` はありません。`toLocation(world)` を使用してください。
+
+```kotlin
+// ❌ 間違い
+position.resolve(baseLocation)
+
+// ✅ 正しい
+position.toLocation(world)
+```
+
+---
+
+## FAQ
+
+**Q: 相対座標 (`~`) は使えますか？**  
+A: はい、`Position` は相対座標を完全にサポートしています。
+
+**Q: 旧バージョンとの互換性は？**  
+A: `coordinates()` の型が変更されているため互換性はありません。他の引数（`player()`, `players()` など）は互換性があります。
+
+**Q: 段階的な移行は可能？**  
+A: `coordinates()` を使用している場合は一度にすべて移行する必要があります。

+- `coordinates()` の返り値が `Coordinates3` から `io.papermc.paper.math.Position` に変更
+- `position.toLocation(world)` で `Location` に変換する方式に変更
+- Player/Entity セレクターの内部処理が改善され、より安定した動作を実現

+## クライアント側構文ヒント (Brigadier)
+
+Paper 1.21 以降の環境では、`LifecycleEventManager` を通じてコマンドが登録されるため、クライアントにコマンドの構造が送信されます。これにより以下のメリットがあります：
+
+- **構文の可視化**: 入力中に `<speed> <amount>` のような引数名が表示されます。
+- **クライアント側検証**: `integer("val", min=1, max=10)` などの範囲指定がクライアント側でも判定され、範囲外の値を入力すると赤字になります。
+- **互換性**: 内部的には `Brigadier` のノードに変換されますが、実際のコマンド実行は `kommand-lib` の既存ロジック（`KommandContext`）を使用するため、古いコードの修正は不要です。
