+# ai.shell統合作業完了報告 (2025/01/06)
+
+## 作業概要
+ai.shellのRust実装をai.gptのPython実装に統合し、Claude Code風のインタラクティブシェル環境を実現。
+
+## 実装完了機能
+
+### 1. aigpt shellコマンド
+**場所**: `src/aigpt/cli.py` - `shell()` 関数
+
+**機能**:
+```bash
+aigpt shell  # インタラクティブシェル起動
+```
+
+**シェル内コマンド**:
+- `help` - コマンド一覧表示
+- `!<command>` - シェルコマンド実行（例: `!ls`, `!pwd`）
+- `analyze <file>` - ファイルをAIで分析
+- `generate <description>` - コード生成
+- `explain <topic>` - 概念説明
+- `load` - aishell.md読み込み
+- `status`, `fortune`, `relationships` - AI状態確認
+- `clear` - 画面クリア
+- `exit`/`quit` - 終了
+- その他のメッセージ - AIとの直接対話
+
+**実装の特徴**:
+- prompt-toolkit使用（補完・履歴機能）
+- ただしターミナル環境依存の問題あり（後で修正必要）
+- 現在は`input()`ベースでも動作
+
+### 2. MCPサーバー統合
+**場所**: `src/aigpt/mcp_server.py`
+
+**FastApiMCP実装パターン**:
+```python
+# FastAPIアプリ作成
+self.app = FastAPI(title="AI.GPT Memory and Relationship System")
+
+# FastApiMCPサーバー作成
+self.server = FastApiMCP(self.app)
+
+# エンドポイント登録
+@self.app.get("/get_memories", operation_id="get_memories")
+async def get_memories(limit: int = 10):
+    # ...
+
+# MCPマウント
+self.server.mount()
+```
+
+**公開ツール (14個)**:
+
+**ai.gpt系 (9個)**:
+- `get_memories` - アクティブメモリ取得
+- `get_relationship` - 特定ユーザーとの関係取得
+- `get_all_relationships` - 全関係取得
+- `get_persona_state` - 人格状態取得
+- `process_interaction` - ユーザー対話処理
+- `check_transmission_eligibility` - 送信可能性チェック
+- `get_fortune` - AI運勢取得
+- `summarize_memories` - メモリ要約作成
+- `run_maintenance` - 日次メンテナンス実行
+
+**ai.shell系 (5個)**:
+- `execute_command` - シェルコマンド実行
+- `analyze_file` - ファイルAI分析
+- `write_file` - ファイル書き込み（バックアップ付き）
+- `read_project_file` - aishell.md等の読み込み
+- `list_files` - ディレクトリファイル一覧
+
+### 3. ai.card統合対応
+**場所**: `src/aigpt/card_integration.py`
+
+**サーバー起動オプション**:
+```bash
+aigpt server --enable-card  # ai.card機能有効化
+```
+
+**ai.card系ツール (5個)**:
+- `get_user_cards` - ユーザーカード取得
+- `draw_card` - ガチャでカード取得
+- `get_card_details` - カード詳細情報
+- `sync_cards_atproto` - atproto同期
+- `analyze_card_collection` - コレクション分析
+
+### 4. プロジェクト仕様書
+**場所**: `aishell.md`
+
+Claude.md的な役割で、プロジェクトの目標と仕様を記述。`load`コマンドでAIが読み取り可能。
+
+## 技術実装詳細
+
+### ディレクトリ構造
+```
+src/aigpt/
+├── cli.py              # shell関数追加
+├── mcp_server.py       # FastApiMCP実装
+├── card_integration.py # ai.card統合
+└── ...                 # 既存ファイル
+```
+
+### 依存関係追加
+`pyproject.toml`:
+```toml
+dependencies = [
+    # ... 既存
+    "prompt-toolkit>=3.0.0",  # 追加
+]
+```
+
+### 名前規則の統一
+- MCP server名: `aigpt` (ai-gptから変更)
+- パッケージ名: `aigpt`
+- コマンド名: `aigpt shell`
+
+## 動作確認済み
+
+### CLI動作確認
+```bash
+# 基本機能
+aigpt shell
+# シェル内で
+ai.shell> help
+ai.shell> !ls
+ai.shell> analyze README.md  # ※AI provider要設定
+ai.shell> load
+ai.shell> exit
+
+# MCPサーバー
+aigpt server --model qwen2.5-coder:7b --port 8001
+# -> http://localhost:8001/docs でAPI確認可能
+# -> /mcp エンドポイントでMCP接続可能
+```
+
+### エラー対応済み
+1. **Pydantic日付型エラー**: `models.py`で`datetime.date`インポート追加
+2. **FastApiMCP使用法**: サンプルコードに基づき正しい実装パターンに修正
+3. **prompt関数名衝突**: `prompt_toolkit.prompt`を`ptk_prompt`にリネーム
+
+## 既知の課題と今後の改善点
+
+### 1. prompt-toolkit環境依存問題
+**症状**: ターミナル環境でない場合にエラー
+**対処法**: 環境検出して`input()`にフォールバック
+**場所**: `src/aigpt/cli.py` - `shell()` 関数
+
+### 2. AI provider設定
+**現状**: ollamaのqwen2.5モデルが必要
+**対処法**: 
+```bash
+ollama pull qwen2.5
+# または
+aigpt shell --model qwen2.5-coder:7b
+```
+
+### 3. atproto実装
+**現状**: ai.cardのatproto機能は未実装
+**今後**: 実際のatproto API連携実装
+
+## 次回開発時の推奨アプローチ
+
+### 1. このドキュメントの活用
+```bash
+# このファイルを読み込み
+cat docs/ai_shell_integration_summary.md
+```
+
+### 2. 環境セットアップ
+```bash
+cd /Users/syui/ai/gpt
+python -m venv venv
+source venv/bin/activate
+pip install -e .
+```
+
+### 3. 動作確認
+```bash
+# shell機能
+aigpt shell
+
+# MCP server
+aigpt server --model qwen2.5-coder:7b
+```
+
+### 4. 主要設定ファイル確認場所
+- CLI実装: `src/aigpt/cli.py`
+- MCP実装: `src/aigpt/mcp_server.py`
+- 依存関係: `pyproject.toml`
+- プロジェクト仕様: `aishell.md`
+
+## アーキテクチャ設計思想
+
+### yui system適用
+- **唯一性**: 各ユーザーとの関係は1:1
+- **不可逆性**: 関係性破壊は修復不可能
+- **現実反映**: ゲーム→現実の循環的影響
+
+### fastapi_mcp統一基盤
+- 各AI（gpt, shell, card）を統合MCPサーバーで公開
+- FastAPIエンドポイント → MCPツール自動変換
+- Claude Desktop, Cursor等から利用可能
+
+### 段階的実装完了
+1. ✅ ai.shell基本機能 → Python CLI
+2. ✅ MCP統合 → 外部AI連携
+3. 🔧 prompt-toolkit最適化 → 環境対応
+4. 🔧 atproto実装 → 本格的SNS連携
+
+## 成果サマリー
+
+**実装済み**: Claude Code風の開発環境
+**技術的成果**: Rust→Python移行、MCP統合、ai.card対応
+**哲学的一貫性**: yui systemとの整合性維持
+**利用可能性**: 即座に`aigpt shell`で体験可能
+
+この統合により、ai.gptは単なる会話AIから、開発支援を含む総合的なAI環境に進化しました。
