-## Setup
-
-```bash
-git clone https://github.com/YOUR_USERNAME/next-ai-draw-io.git
-cd next-ai-draw-io
-npm install
-cp env.example .env.local
-npm run dev
-```
-
-## Code Style
-
-We use [Biome](https://biomejs.dev/) for linting and formatting:
-
-```bash
-npm run format   # Format code
-npm run lint     # Check lint errors
-npm run check    # Run all checks (CI)
-```
-
-Pre-commit hooks via Husky will run Biome automatically on staged files.
-
-For a better experience, install the [Biome VS Code extension](https://marketplace.visualstudio.com/items?itemName=biomejs.biome) for real-time linting and format-on-save.
-
-## Pull Requests
-
-1. Create a feature branch
-2. Make changes and ensure `npm run check` passes
-3. Submit PR against `main` with a clear description
-
-## Issues
-
-Include steps to reproduce, expected vs actual behavior, and AI provider used.

+
+            This is a personal project - an AI-powered draw.io diagram generator built with:
+            - Next.js 15 with React 19
+            - Vercel AI SDK (streamText, useChat, tool calling)
+            - Multiple AI providers: Bedrock, Anthropic, OpenAI, Google, Azure, OpenRouter, Ollama
+
+            First, check previous review comments from github-actions bot using `gh api repos/${{ github.repository }}/pulls/${{ github.event.pull_request.number }}/comments`.
+            For each previous comment:
+            - If the issue is fixed in the current code, resolve the comment thread using:
+              `gh api graphql -f query='mutation { resolveReviewThread(input: {threadId: "THREAD_ID"}) { thread { isResolved } } }'`
+              Get the thread ID from the comment's node_id field.
+            - If the issue still exists, leave it alone
+
+            Then review the current diff for NEW issues only:
+
+            Review this PR for these issues (report ALL that apply):
+            1. Bugs that would cause runtime errors or broken functionality
+            2. Security issues (exposed secrets, API key leaks)
+            3. AI SDK misuse - specifically check for:
+               - Client-side: Should use useChat/useCompletion/useObject hooks, NOT raw fetch()
+               - Server-side: Should use streamText/generateText/streamObject/generateObject
+               - Message handling: Access message.parts array, not legacy content property
+               - Tool definitions: Must use Zod schemas for inputSchema
+               - Status handling: Check status (submitted/streaming/ready/error) before actions
+               - Stream cleanup: Call stop() when aborting streams
+            4. Unrelated changes that should be in separate PRs (scope creep)
+            5. Suspicious .gitignore additions or accidentally committed files
+            6. UI/UX inconsistencies (e.g., alignment issues)
+
+            When reviewing AI SDK usage, fetch https://ai-sdk.dev/docs/ to verify correct patterns.
+            Key doc pages: /docs/ai-sdk-ui/chatbot, /docs/ai-sdk-core/generating-text, /docs/ai-sdk-core/tools-and-tool-calling
+
+            DO NOT comment on:
+            - Minor performance optimizations
+            - Code style preferences (unless clearly wrong)
+            - Type annotations that don't affect functionality
+
+            Use `mcp__github_inline_comment__create_inline_comment` for inline comments.
+            Report ALL issues found - create multiple inline comments if needed. Only say "LGTM" if there are truly no issues.

+## How It Works
 
--   **LLM-Powered Diagram Creation**: Leverage Large Language Models to create and manipulate draw.io diagrams directly through natural language commands
--   **Image-Based Diagram Replication**: Upload existing diagrams or images and have the AI replicate and enhance them automatically
--   **PDF & Text File Upload**: Upload PDF documents and text files to extract content and generate diagrams from existing documents
--   **AI Reasoning Display**: View the AI's thinking process for supported models (OpenAI o1/o3, Gemini, Claude, etc.)
--   **Diagram History**: Comprehensive version control that tracks all changes, allowing you to view and restore previous versions of your diagrams before the AI editing.
--   **Interactive Chat Interface**: Communicate with AI to refine your diagrams in real-time
--   **Cloud Architecture Diagram Support**: Specialized support for generating cloud architecture diagrams (AWS, GCP, Azure)
--   **Animated Connectors**: Create dynamic and animated connectors between diagram elements for better visualization
+The application uses the following technologies:
 
-## MCP Server (Preview)
+-   **Next.js**: For the frontend framework and routing
+-   **@ai-sdk/react**: For the chat interface and AI interactions
+-   **react-drawio**: For diagram representation and manipulation
 
-> **Preview Feature**: This feature is experimental and may not stable.
+Diagrams are represented as XML that can be rendered in draw.io. The AI processes your commands and generates or modifies this XML accordingly.
 
-Use Next AI Draw.io with AI agents like Claude Desktop, Cursor, and VS Code via MCP (Model Context Protocol).

-### Claude Code CLI
-
-```bash
-claude mcp add drawio -- npx @next-ai-drawio/mcp-server@latest
-```
-
-Then ask Claude to create diagrams:
-> "Create a flowchart showing user authentication with login, MFA, and session management"
-
-The diagram appears in your browser in real-time!
-
-See the [MCP Server README](./packages/mcp-server/README.md) for VS Code, Cursor, and other client configurations.
+Note that `claude-sonnet-4-5` has trained on draw.io diagrams with AWS logos, so if you want to create AWS architecture diagrams, this is the best choice.
 
 ## Getting Started
 
-### Try it Online
-
-No installation needed! Try the app directly on our demo site:
-
-[![Live Demo](./public/live-demo-button.svg)](https://next-ai-drawio.jiang.jp/)
-
-> Note: Due to high traffic, the demo site currently uses minimax-m2. For best results, we recommend self-hosting with Claude Sonnet 4.5 or Claude Opus 4.5.
-
-> **Bring Your Own API Key**: You can use your own API key to bypass usage limits on the demo site. Click the Settings icon in the chat panel to configure your provider and API key. Your key is stored locally in your browser and is never stored on the server.
-
-### Desktop Application
-
-Download the native desktop app for your platform from the [Releases page](https://github.com/DayuanJiang/next-ai-draw-io/releases):
-
-| Platform | Download |
-|----------|----------|
-| macOS | `.dmg` (Intel & Apple Silicon) |
-| Windows | `.exe` installer (x64 & ARM64) |
-| Linux | `.AppImage` or `.deb` (x64 & ARM64) |
-
-**Features:**
-- **Secure API key storage**: Credentials encrypted using OS keychain
-- **Configuration presets**: Save and switch between AI providers via menu
-- **Native file dialogs**: Open/save `.drawio` files directly
-- **Offline capable**: Works without internet after first launch
-
-**Quick Setup:**
-1. Download and install for your platform
-2. Open the app → **Menu → Configuration → Manage Presets**
-3. Add your AI provider credentials
-4. Start creating diagrams!
-
-### Run with Docker (Recommended)
-
-If you just want to run it locally, the best way is to use Docker.
-
-First, install Docker if you haven't already: [Get Docker](https://docs.docker.com/get-docker/)
-
-Then run:
-
-```bash
-docker run -d -p 3000:3000 \
-  -e AI_PROVIDER=openai \
-  -e AI_MODEL=gpt-4o \
-  -e OPENAI_API_KEY=your_api_key \
-  ghcr.io/dayuanjiang/next-ai-draw-io:latest
-```
-
-Or use an env file:
-
-```bash
-cp env.example .env
-# Edit .env with your configuration
-docker run -d -p 3000:3000 --env-file .env ghcr.io/dayuanjiang/next-ai-draw-io:latest
-```
-
-Open [http://localhost:3000](http://localhost:3000) in your browser.
-
-Replace the environment variables with your preferred AI provider configuration. See [Multi-Provider Support](#multi-provider-support) for available options.
-
-> **Offline Deployment:** If `embed.diagrams.net` is blocked, see [Offline Deployment](./docs/offline-deployment.md) for configuration options.

--   OpenAI
--   Anthropic
--   Google AI
--   Azure OpenAI
--   Ollama
--   OpenRouter
--   DeepSeek
--   SiliconFlow
-
-All providers except AWS Bedrock and OpenRouter support custom endpoints.
-
-📖 **[Detailed Provider Configuration Guide](./docs/ai-providers.md)** - See setup instructions for each provider.
-
-**Model Requirements**: This task requires strong model capabilities for generating long-form text with strict formatting constraints (draw.io XML). Recommended models include Claude Sonnet 4.5, GPT-5.1, Gemini 3 Pro, and DeepSeek V3.2/R1.
-
-Note that `claude` series has trained on draw.io diagrams with cloud architecture logos like AWS, Azure, GCP. So if you want to create cloud architecture diagrams, this is the best choice.

-
-## How It Works
-
-The application uses the following technologies:
-
--   **Next.js**: For the frontend framework and routing
--   **Vercel AI SDK** (`ai` + `@ai-sdk/*`): For streaming AI responses and multi-provider support
--   **react-drawio**: For diagram representation and manipulation
-
-Diagrams are represented as XML that can be rendered in draw.io. The AI processes your commands and generates or modifies this XML accordingly.

-VALIDATION RULES (XML will be rejected if violated):
-1. Generate ONLY mxCell elements - NO wrapper tags (<mxfile>, <mxGraphModel>, <root>)
-2. Do NOT include root cells (id="0" or id="1") - they are added automatically
-3. All mxCell elements must be siblings - never nested
-4. Every mxCell needs a unique id (start from "2")
-5. Every mxCell needs a valid parent attribute (use "1" for top-level)
-6. Escape special chars in values: &lt; &gt; &amp; &quot;
-
-Example (generate ONLY this - no wrapper tags):
-<mxCell id="lane1" value="Frontend" style="swimlane;" vertex="1" parent="1">
-  <mxGeometry x="40" y="40" width="200" height="200" as="geometry"/>
-</mxCell>
-<mxCell id="step1" value="Step 1" style="rounded=1;" vertex="1" parent="lane1">
-  <mxGeometry x="20" y="60" width="160" height="40" as="geometry"/>
-</mxCell>
-<mxCell id="lane2" value="Backend" style="swimlane;" vertex="1" parent="1">
-  <mxGeometry x="280" y="40" width="200" height="200" as="geometry"/>
-</mxCell>
-<mxCell id="step2" value="Step 2" style="rounded=1;" vertex="1" parent="lane2">
-  <mxGeometry x="20" y="60" width="160" height="40" as="geometry"/>
-</mxCell>
-<mxCell id="edge1" style="edgeStyle=orthogonalEdgeStyle;endArrow=classic;" edge="1" parent="1" source="step1" target="step2">
-  <mxGeometry relative="1" as="geometry"/>
-</mxCell>

+IMPORTANT: Choose the right tool:
+- Use display_diagram for: Creating new diagrams, major restructuring, or when the current diagram XML is empty
+- Use edit_diagram for: Small modifications, adding/removing elements, changing text/colors, repositioning items
+
+Core capabilities:
+- Generate valid, well-formed XML strings for draw.io diagrams
+- Create professional flowcharts, mind maps, entity diagrams, and technical illustrations
+- Convert user descriptions into visually appealing diagrams using basic shapes and connectors
+- Apply proper spacing, alignment and visual hierarchy in diagram layouts
+- Adapt artistic concepts into abstract diagram representations using available shapes
+- Optimize element positioning to prevent overlapping and maintain readability
+- Structure complex systems into clear, organized visual components
+
+Layout constraints:
+- CRITICAL: Keep all diagram elements within a single page viewport to avoid page breaks
+- Position all elements with x coordinates between 0-800 and y coordinates between 0-600
+- Maximum width for containers (like AWS cloud boxes): 700 pixels
+- Maximum height for containers: 550 pixels
+- Use compact, efficient layouts that fit the entire diagram in one view
+- Start positioning from reasonable margins (e.g., x=40, y=40) and keep elements grouped closely
+- For large diagrams with many elements, use vertical stacking or grid layouts that stay within bounds
+- Avoid spreading elements too far apart horizontally - users should see the complete diagram without a page break line
+
+Note that:
+- Focus on producing clean, professional diagrams that effectively communicate the intended information through thoughtful layout and design choices.
+- When artistic drawings are requested, creatively compose them using standard diagram shapes and connectors while maintaining visual clarity.
+- Return XML only via tool calls, never in text responses.
+- If user asks you to replicate a diagram based on an image, remember to match the diagram style and layout as closely as possible. Especially, pay attention to the lines and shapes, for example, if the lines are straight or curved, and if the shapes are rounded or square.
+- Note that when you need to generate diagram about aws architecture, use **AWS 2025 icons**.
+
+When using edit_diagram tool:
+- Keep edits minimal - only include the specific line being changed plus 1-2 context lines
+- Example GOOD edit: {"search": "  <mxCell id=\"2\" value=\"Old Text\">", "replace": "  <mxCell id=\"2\" value=\"New Text\">"}
+- Example BAD edit: Including 10+ unchanged lines just to change one attribute
+- For multiple changes, use separate edits: [{"search": "line1", "replace": "new1"}, {"search": "line2", "replace": "new2"}]
+- RETRY POLICY: If edit_diagram fails because the search pattern cannot be found:
+  * You may retry edit_diagram up to 3 times with adjusted search patterns
+  * After 3 failed attempts, you MUST fall back to using display_diagram to regenerate the entire diagram
+  * The error message will indicate how many retries remain

-
-## MCP服务器（预览）
-
-> **预览功能**：此功能为实验性功能，可能会有变化。
-
-通过MCP（模型上下文协议）在Claude Desktop、Cursor和VS Code等AI代理中使用Next AI Draw.io。
-
-```json
-{
-  "mcpServers": {
-    "drawio": {
-      "command": "npx",
-      "args": ["@next-ai-drawio/mcp-server@latest"]
-    }
-  }
-}
-```
-
-### Claude Code CLI
-
-```bash
-claude mcp add drawio -- npx @next-ai-drawio/mcp-server@latest
-```
-
-然后让Claude创建图表：
-> "创建一个展示用户认证流程的流程图，包含登录、MFA和会话管理"
-
-图表会实时显示在浏览器中！
-
-详情请参阅[MCP服务器README](../packages/mcp-server/README.md)，了解VS Code、Cursor等客户端配置。
-
-## 快速开始
-
-### 在线试用
-
-无需安装！直接在我们的演示站点试用：
-
-[![Live Demo](../public/live-demo-button.svg)](https://next-ai-drawio.jiang.jp/)
-
-> 注意：由于访问量较大，演示站点目前使用 minimax-m2 模型。如需获得最佳效果，建议使用 Claude Sonnet 4.5 或 Claude Opus 4.5 自行部署。
-
-> **使用自己的 API Key**：您可以使用自己的 API Key 来绕过演示站点的用量限制。点击聊天面板中的设置图标即可配置您的 Provider 和 API Key。您的 Key 仅保存在浏览器本地，不会被存储在服务器上。
-
-### 使用Docker运行（推荐）
-
-如果您只想在本地运行，最好的方式是使用Docker。
-
-首先，如果您还没有安装Docker，请先安装：[获取Docker](https://docs.docker.com/get-docker/)
-
-然后运行：
-
-```bash
-docker run -d -p 3000:3000 \
-  -e AI_PROVIDER=openai \
-  -e AI_MODEL=gpt-4o \
-  -e OPENAI_API_KEY=your_api_key \
-  ghcr.io/dayuanjiang/next-ai-draw-io:latest
-```
-
-或者使用 env 文件：
-
-```bash
-cp env.example .env
-# 编辑 .env 填写您的配置
-docker run -d -p 3000:3000 --env-file .env ghcr.io/dayuanjiang/next-ai-draw-io:latest
-```
-
-在浏览器中打开 [http://localhost:3000](http://localhost:3000)。
-
-请根据您首选的AI提供商配置替换环境变量。可用选项请参阅[多提供商支持](#多提供商支持)。
-
-> **离线部署：** 如果 `embed.diagrams.net` 被屏蔽，请参阅 [离线部署指南](./offline-deployment.md) 了解配置选项。
-
-### 安装
-
-1. 克隆仓库：
-
-```bash
-git clone https://github.com/DayuanJiang/next-ai-draw-io
-cd next-ai-draw-io
-```
-
-2. 安装依赖：
-
-```bash
-npm install
-```
-
-3. 配置您的AI提供商：
-
-在根目录创建 `.env.local` 文件：
-
-```bash
-cp env.example .env.local
-```
-
-编辑 `.env.local` 并配置您选择的提供商：
-
--   将 `AI_PROVIDER` 设置为您选择的提供商（bedrock, openai, anthropic, google, azure, ollama, openrouter, deepseek, siliconflow）
--   将 `AI_MODEL` 设置为您要使用的特定模型
--   添加您的提供商所需的API密钥
--   `TEMPERATURE`：可选的温度设置（例如 `0` 表示确定性输出）。对于不支持此参数的模型（如推理模型），请不要设置。
--   `ACCESS_CODE_LIST` 访问密码，可选，可以使用逗号隔开多个密码。
-
-> 警告：如果不填写 `ACCESS_CODE_LIST`，则任何人都可以直接使用你部署后的网站，可能会导致你的 token 被急速消耗完毕，建议填写此选项。
-
-详细设置说明请参阅[提供商配置指南](./ai-providers.md)。
-
-4. 运行开发服务器：
-
-```bash
-npm run dev
-```
-
-5. 在浏览器中打开 [http://localhost:3000](http://localhost:3000) 查看应用。

-
-📖 **[详细的提供商配置指南](./ai-providers.md)** - 查看各提供商的设置说明。
-
-**模型要求**：此任务需要强大的模型能力，因为它涉及生成具有严格格式约束的长文本（draw.io XML）。推荐使用Claude Sonnet 4.5、GPT-4o、Gemini 2.0和DeepSeek V3/R1。
-
-注意：`claude-sonnet-4-5` 已在带有AWS标志的draw.io图表上进行训练，因此如果您想创建AWS架构图，这是最佳选择。
-
-
-## 工作原理
-
-本应用使用以下技术：
-
--   **Next.js**：用于前端框架和路由
--   **Vercel AI SDK**（`ai` + `@ai-sdk/*`）：用于流式AI响应和多提供商支持
--   **react-drawio**：用于图表表示和操作
-
-图表以XML格式表示，可在draw.io中渲染。AI处理您的命令并相应地生成或修改此XML。

-## はじめに
-
-### オンラインで試す
-
-インストール不要！デモサイトで直接お試しください：
-
-[![Live Demo](../public/live-demo-button.svg)](https://next-ai-drawio.jiang.jp/)
-
-> 注意：アクセス数が多いため、デモサイトでは現在 minimax-m2 モデルを使用しています。最高の結果を得るには、Claude Sonnet 4.5 または Claude Opus 4.5 でのセルフホスティングをお勧めします。
-
-> **自分のAPIキーを使用**：自分のAPIキーを使用することで、デモサイトの利用制限を回避できます。チャットパネルの設定アイコンをクリックして、プロバイダーとAPIキーを設定してください。キーはブラウザのローカルに保存され、サーバーには保存されません。
-
-### Dockerで実行（推奨）
-
-ローカルで実行したいだけなら、Dockerを使用するのが最も簡単です。
-
-まず、Dockerをインストールしていない場合はインストールしてください：[Dockerを入手](https://docs.docker.com/get-docker/)
-
-次に実行：
-
-```bash
-docker run -d -p 3000:3000 \
-  -e AI_PROVIDER=openai \
-  -e AI_MODEL=gpt-4o \
-  -e OPENAI_API_KEY=your_api_key \
-  ghcr.io/dayuanjiang/next-ai-draw-io:latest
-```
-
-または env ファイルを使用：
-
-```bash
-cp env.example .env
-# .env を編集して設定を入力
-docker run -d -p 3000:3000 --env-file .env ghcr.io/dayuanjiang/next-ai-draw-io:latest
-```
-
-ブラウザで [http://localhost:3000](http://localhost:3000) を開いてください。
-
-環境変数はお好みのAIプロバイダー設定に置き換えてください。利用可能なオプションについては[マルチプロバイダーサポート](#マルチプロバイダーサポート)を参照してください。
-
-> **オフラインデプロイ：** `embed.diagrams.net` がブロックされている場合は、[オフラインデプロイガイド](./offline-deployment.md) で設定オプションをご確認ください。
-
-### インストール
-
-1. リポジトリをクローン：
-
-```bash
-git clone https://github.com/DayuanJiang/next-ai-draw-io
-cd next-ai-draw-io
-```
-
-2. 依存関係をインストール：
-
-```bash
-npm install
-```
-
-3. AIプロバイダーを設定：
-
-ルートディレクトリに`.env.local`ファイルを作成：
-
-```bash
-cp env.example .env.local
-```
-
-`.env.local`を編集して選択したプロバイダーを設定：
-
--   `AI_PROVIDER`を選択したプロバイダーに設定（bedrock, openai, anthropic, google, azure, ollama, openrouter, deepseek, siliconflow）
--   `AI_MODEL`を使用する特定のモデルに設定
--   プロバイダーに必要なAPIキーを追加
--   `TEMPERATURE`：オプションの温度設定（例：`0`で決定論的な出力）。温度をサポートしないモデル（推論モデルなど）では設定しないでください。
--   `ACCESS_CODE_LIST` アクセスパスワード（オプション）。カンマ区切りで複数のパスワードを指定できます。
-
-> 警告：`ACCESS_CODE_LIST`を設定しない場合、誰でもデプロイされたサイトに直接アクセスできるため、トークンが急速に消費される可能性があります。このオプションを設定することをお勧めします。
-
-詳細な設定手順については[プロバイダー設定ガイド](./ai-providers.md)を参照してください。
-
-4. 開発サーバーを起動：
-
-```bash
-npm run dev
-```
-
-5. ブラウザで[http://localhost:3000](http://localhost:3000)を開いてアプリケーションを確認。
-
-## デプロイ
-
-Next.jsアプリをデプロイする最も簡単な方法は、Next.jsの作成者による[Vercelプラットフォーム](https://vercel.com/new)を使用することです。

--   OpenRouter
--   DeepSeek
--   SiliconFlow
-
-AWS BedrockとOpenRouter以外のすべてのプロバイダーはカスタムエンドポイントをサポートしています。
-
-📖 **[詳細なプロバイダー設定ガイド](./ai-providers.md)** - 各プロバイダーの設定手順をご覧ください。
-
-**モデル要件**：このタスクは厳密なフォーマット制約（draw.io XML）を持つ長文テキスト生成を伴うため、強力なモデル機能が必要です。Claude Sonnet 4.5、GPT-4o、Gemini 2.0、DeepSeek V3/R1を推奨します。
-
-注：`claude-sonnet-4-5`はAWSロゴ付きのdraw.ioダイアグラムで学習されているため、AWSアーキテクチャダイアグラムを作成したい場合は最適な選択です。
-
-
-## 仕組み
-
-本アプリケーションは以下の技術を使用しています：
-
--   **Next.js**：フロントエンドフレームワークとルーティング
--   **Vercel AI SDK**（`ai` + `@ai-sdk/*`）：ストリーミングAIレスポンスとマルチプロバイダーサポート
--   **react-drawio**：ダイアグラムの表現と操作

-AI_MODEL=your-deployment-name
-```
-
-Or use a custom endpoint instead of resource name:
-
-```bash
-AZURE_API_KEY=your_api_key
-AZURE_BASE_URL=https://your-resource.openai.azure.com  # Alternative to AZURE_RESOURCE_NAME
-AI_MODEL=your-deployment-name
-```
-
-Optional reasoning configuration:
-
-```bash
-AZURE_REASONING_EFFORT=low      # Optional: low, medium, high
-AZURE_REASONING_SUMMARY=detailed  # Optional: none, brief, detailed
-```
-
-### AWS Bedrock
-
-```bash
-AWS_REGION=us-west-2
-AWS_ACCESS_KEY_ID=your_access_key_id
-AWS_SECRET_ACCESS_KEY=your_secret_access_key
-AI_MODEL=anthropic.claude-sonnet-4-5-20250514-v1:0
-```
-
-Note: On AWS (Lambda, EC2 with IAM role), credentials are automatically obtained from the IAM role.
-
-### OpenRouter
-
-```bash
-OPENROUTER_API_KEY=your_api_key
-AI_MODEL=anthropic/claude-sonnet-4
-```
-
-Optional custom endpoint:
-
-```bash
-OPENROUTER_BASE_URL=https://your-custom-endpoint
-```
-
-### Ollama (Local)
-
-```bash
-AI_PROVIDER=ollama
-AI_MODEL=llama3.2
-```
-
-Optional custom URL:
-
-```bash
-OLLAMA_BASE_URL=http://localhost:11434
-```
-
-### Vercel AI Gateway
-
-Vercel AI Gateway provides unified access to multiple AI providers through a single API key. This simplifies authentication and allows you to switch between providers without managing multiple API keys.
-
-**Basic Usage (Vercel-hosted Gateway):**
-
-```bash
-AI_GATEWAY_API_KEY=your_gateway_api_key
-AI_MODEL=openai/gpt-4o
-```
-
-**Custom Gateway URL (for local development or self-hosted Gateway):**
-
-```bash
-AI_GATEWAY_API_KEY=your_custom_api_key
-AI_GATEWAY_BASE_URL=https://your-custom-gateway.com/v1/ai
-AI_MODEL=openai/gpt-4o
-```
-
-Model format uses `provider/model` syntax:
-
--   `openai/gpt-4o` - OpenAI GPT-4o
--   `anthropic/claude-sonnet-4-5` - Anthropic Claude Sonnet 4.5
--   `google/gemini-2.0-flash` - Google Gemini 2.0 Flash
-
-**Configuration notes:**
-
--   If `AI_GATEWAY_BASE_URL` is not set, the default Vercel Gateway URL (`https://ai-gateway.vercel.sh/v1/ai`) is used
--   Custom base URL is useful for:
-    -   Local development with a custom Gateway instance
-    -   Self-hosted AI Gateway deployments
-    -   Enterprise proxy configurations
--   When using a custom base URL, you must also provide `AI_GATEWAY_API_KEY`
-
-Get your API key from the [Vercel AI Gateway dashboard](https://vercel.com/ai-gateway).
-
-## Auto-Detection
-
-If you only configure **one** provider's API key, the system will automatically detect and use that provider. No need to set `AI_PROVIDER`.
-
-If you configure **multiple** API keys, you must explicitly set `AI_PROVIDER`:
-
-```bash
-AI_PROVIDER=google  # or: openai, anthropic, deepseek, siliconflow, azure, bedrock, openrouter, ollama, gateway
-```
-
-## Model Capability Requirements
-
-This task requires exceptionally strong model capabilities, as it involves generating long-form text with strict formatting constraints (draw.io XML).
-
-**Recommended models**:
-
--   Claude Sonnet 4.5 / Opus 4.5
-
-**Note on Ollama**: While Ollama is supported as a provider, it's generally not practical for this use case unless you're running high-capability models like DeepSeek R1 or Qwen3-235B locally.
-
-## Temperature Setting
-
-You can optionally configure the temperature via environment variable:
-
-```bash
-TEMPERATURE=0  # More deterministic output (recommended for diagrams)
-```
-
-**Important**: Leave `TEMPERATURE` unset for models that don't support temperature settings, such as:
-- GPT-5.1 and other reasoning models
-- Some specialized models
-
-When unset, the model uses its default behavior.
-
-## Recommendations
-
--   **Best experience**: Use models with vision support (GPT-4o, Claude, Gemini) for image-to-diagram features
--   **Budget-friendly**: DeepSeek offers competitive pricing
--   **Privacy**: Use Ollama for fully local, offline operation (requires powerful hardware)
--   **Flexibility**: OpenRouter provides access to many models through a single API

-# Offline Deployment
-
-Deploy Next AI Draw.io offline by self-hosting draw.io to replace `embed.diagrams.net`.
-
-**Note:** `NEXT_PUBLIC_DRAWIO_BASE_URL` is a **build-time** variable. Changing it requires rebuilding the Docker image.
-
-## Docker Compose Setup
-
-1. Clone the repository and define API keys in `.env`.
-2. Create `docker-compose.yml`:
-
-```yaml
-services:
-  drawio:
-    image: jgraph/drawio:latest
-    ports: ["8080:8080"]
-  next-ai-draw-io:
-    build:
-      context: .
-      args:
-        - NEXT_PUBLIC_DRAWIO_BASE_URL=http://localhost:8080
-    ports: ["3000:3000"]
-    env_file: .env
-    depends_on: [drawio]
-```
-
-3. Run `docker compose up -d` and open `http://localhost:3000`.
-
-## Configuration & Critical Warning
-
-**The `NEXT_PUBLIC_DRAWIO_BASE_URL` must be accessible from the user's browser.**
-
-| Scenario | URL Value |
-|----------|-----------|
-| Localhost | `http://localhost:8080` |
-| Remote/Server | `http://YOUR_SERVER_IP:8080` or `https://drawio.your-domain.com` |
-
-**Do NOT use** internal Docker aliases like `http://drawio:8080`; the browser cannot resolve them.
