Implementation Reference

• src/tools/player.ts:134-180 (handler)

  The core logic for `view_inventory` which reads the player data and formats the inventory content string.

  export async function viewInventory(saveKey: string): Promise<string> {
    const data = await storage.load(saveKey);
  
    if (!data.player.name) {
      return "プレイヤーが見つかりません。先に'create_player'を実行してください。";
    }
  
    const hasEquipment = data.player.inventory.length > 0;
    const hasItems = (data.player.itemInventory?.length || 0) > 0;
  
    if (!hasEquipment && !hasItems) {
      return "インベントリは空です。";
    }
  
    let output = `=== インベントリ ===\n\n`;
  
    // 装備インベントリ
    if (hasEquipment) {
      output += `【装備】 (${data.player.inventory.length}個)\n\n`;
  
      const groupedByType: { [key: string]: Equipment[] } = {};
  
      for (const item of data.player.inventory) {
        if (!groupedByType[item.type]) {
          groupedByType[item.type] = [];
        }
        groupedByType[item.type].push(item);
      }
  
      const typeNames: { [key: string]: string } = {
        weapon: '武器',
        shield: '盾',
        armor: '防具',
        accessory: 'アクセサリ'
      };
  
      for (const [type, items] of Object.entries(groupedByType)) {
        output += `${typeNames[type] || type}:\n`;
        for (const item of items) {
          output += `  [${item.id}] ${item.name} [${item.rarity}]\n`;
          output += `    攻撃+${item.stats.attack} 防御+${item.stats.defense} 速度+${item.stats.speed} 運+${item.stats.luck}\n`;
        }
        output += '\n';
      }
    }
  
    // 持ち物インベントリ

• src/index.ts:77-88 (registration)

  Tool registration for `view_inventory` with its schema definition in `src/index.ts`.

  name: 'view_inventory',
  description: 'インベントリ内のすべてのアイテムを表示します。',
  inputSchema: {
    type: 'object',
    properties: {
      save_key: {
        type: 'string',
        description: 'セーブキー',
      },
    },
    required: ['save_key'],
  },

• src/index.ts:326-334 (handler)

  The switch-case handler in `src/index.ts` that dispatches the `view_inventory` request to the implementation in `playerTools`.

  case 'view_inventory':
    return {
      content: [
        {
          type: 'text',
          text: await playerTools.viewInventory(args.save_key as string),
        },
      ],
    };
