あなたはエンジニアとして、私専用の「Androidタブレット（低スペックCPUのみ）で完全自立型、外部APIや有料ツール不要で動くコード生成AI」を作ってください。

Browse files

私が指示を入力すると、自動で以下を順番に実行するWebアプリとして完成させてください。追加指示なしで動作します。

## 基本方針
1. **ブラウザベース**
- Android Chrome/Firefox で動作
- インストール不要、ローカル完全動作
2. **完全オフライン対応**
- ネットワークなしでコード生成・バグ修正・目標設定
- モデルやテンプレートはローカルキャッシュ（IndexedDBなど）に保存
3. **軽量モデル**
- CodeLlama-mini, StarCoder-mini, Mistral 7B-instruct 等、WASM対応の軽量LLMを使用
- CPUのみで推論可能
- モデルが重すぎる場合はオフラインテンプレートで最低限のコード生成

## 必須機能
1. **コード生成**
- Python / JavaScript / C / C++ / Java / HTML / CSS に対応
- 入力した自然言語指示 → コード生成
- スニペットからファイル単位まで対応
2. **バグ修正**
- 実行時や構文エラーを自動検出
- 修正コードを生成し、元コードとの比較表示
3. **目標設定と管理**
- 「やりたいこと」を入力すると、自動で目標を生成
- 目標を分解し優先度付けし、コード生成に反映
- 進捗状況の可視化
4. **補助機能**
- 生成コードの行ごとの解説
- 可読性・パフォーマンスの最適化提案
- ドキュメント自動生成（docstring, README）
- 学習モード（練習問題＋解答生成）
5. **履歴管理**
- 生成コード・修正・目標設定の履歴を保存
- 過去の履歴を呼び出して再生成可能
6. **オフラインフォールバック**
- モデルがロードできない場合は内蔵テンプレートで最低限のコードを生成
- Hello World, 簡単なアルゴリズム, 再帰関数など

## UI要件（タブレット向け）
- タッチ操作に最適化（大きめボタン・テキストエリア）
- タブ切替で「コード生成」「解説」「履歴」「目標設定」
- コピー・ダウンロードボタンを配置
- 入力指示 → 自動生成 → バグ修正 → 目標管理までワンクリックで完結

## 技術要件
- HTML+JS で軽量Webアプリとして構築
- WASM対応の軽量LLMを使用してCPUで推論
- モデルロードが難しい場合は事前にテンプレートで補完
- IndexedDB/localStorage で履歴と目標管理を保存
- 完全ローカル動作、ネットワーク不要
- README にセットアップ・使い方・操作例を明記
- バグがない完成版として出力

## 出力形式
- フルプロジェクト一式：
- ソースコード（HTML/JS/必要なWASMモデルファイル）
- フォルダ構成
- 依存関係ファイル（package.jsonなど）
- README（セットアップ・操作方法・使用例）
- 生成コード・修正・目標設定まで自動で行える完成版
- 追加指示なしで動作する状態で出力
