--   **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
+-   **Vercel AI SDK** (`ai` + `@ai-sdk/*`): For streaming AI responses and multi-provider support
+-   **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
+All providers except AWS Bedrock and OpenRouter support custom endpoints.
 
-```bash
-claude mcp add drawio -- npx @next-ai-drawio/mcp-server@latest
-```
+📖 **[Detailed Provider Configuration Guide](./docs/ai-providers.md)** - See setup instructions for each provider.
 
-Then ask Claude to create diagrams:
-> "Create a flowchart showing user authentication with login, MFA, and session management"
+**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-4o, Gemini 2.0, and DeepSeek V3/R1.
 
-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/)
-
-
-
-> **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 |

-**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.
+Be sure to **set the environment variables** in the Vercel dashboard as you did in your local `.env.local` file.

-## 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
-
-ダイアグラムはdraw.ioでレンダリングできるXMLとして表現されます。AIがコマンドを処理し、それに応じてこのXMLを生成または変更します。

 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;
+1. All mxCell elements must be DIRECT children of <root> - never nested
+2. Every mxCell needs a unique id
+3. Every mxCell (except id="0") needs a valid parent attribute
+4. Edge source/target must reference existing cell IDs
+5. Escape special chars in values: &lt; &gt; &amp; &quot;
+6. Always start with: <mxCell id="0"/><mxCell id="1" parent="0"/>
 
-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>
+Example with swimlanes and edges (note: all mxCells are siblings):
+<root>

+CRITICAL: Copy-paste the EXACT search pattern from the "Current diagram XML" in system context. Do NOT reorder attributes or reformat - the attribute order in draw.io XML varies and you MUST match it exactly.
+IMPORTANT: Keep edits concise:
+- COPY the exact mxCell line from the current XML (attribute order matters!)
+- Only include the lines that are changing, plus 1-2 surrounding lines for context if needed
+- Break large changes into multiple smaller edits
+- Each search must contain complete lines (never truncate mid-line)
+- First match only - be specific enough to target the right element
 
-Operations:
-- update: Replace an existing cell by its id. Provide cell_id and complete new_xml.
-- add: Add a new cell. Provide cell_id (new unique id) and new_xml.
-- delete: Remove a cell by its id. Only cell_id is needed.
-
-For update/add, new_xml must be a complete mxCell element including mxGeometry.
-
-⚠️ JSON ESCAPING: Every " inside new_xml MUST be escaped as \\". Example: id=\\"5\\" value=\\"Label\\"

-# Deploy on Cloudflare Workers
-
-This project can be deployed as a **Cloudflare Worker** using the **OpenNext adapter**, giving you:
-
-- Global edge deployment
-- Very low latency
-- Free `workers.dev` hosting
-- Full Next.js ISR support via R2 (optional)
-
-> **Important Windows Note:** OpenNext and Wrangler are **not fully reliable on native Windows**. Recommended options:
->
-> - Use **GitHub Codespaces** (works perfectly)
-> - OR use **WSL (Linux)**
->
-> Pure Windows builds may fail due to WASM file path issues.
-
----
-
-## Prerequisites
-
-1. A **Cloudflare account** (free tier works for basic deployment)
-2. **Node.js 18+**
-3. **Wrangler CLI** installed (dev dependency is fine):
-
-```bash
-npm install -D wrangler
-```
-
-4. Cloudflare login:
-
-```bash
-npx wrangler login
-```
-
-> **Note:** A payment method is only required if you want to enable R2 for ISR caching. Basic Workers deployment is free.
-
----
-
-## Step 1 — Install dependencies
-
-```bash
-npm install
-```
-
----
-
-## Step 2 — Configure environment variables
-
-Cloudflare uses a different file for local testing.
-
-### 1) Create `.dev.vars` (for Cloudflare local + deploy)
-
-```bash
-cp env.example .dev.vars
-```
-
-Fill in your API keys and configuration.
-
-### 2) Make sure `.env.local` also exists (for regular Next.js dev)
-
-```bash
-cp env.example .env.local
-```
-
-Fill in the same values there.
-
----
-
-## Step 3 — Choose your deployment type
-
-### Option A: Deploy WITHOUT R2 (Simple, Free)
-
-If you don't need ISR caching, you can deploy without R2:
-
-**1. Use simple `open-next.config.ts`:**
-
-```ts
-import { defineCloudflareConfig } from "@opennextjs/cloudflare/config"
-
-export default defineCloudflareConfig({})
-```
-
-**2. Use simple `wrangler.jsonc` (without r2_buckets):**
-
-```jsonc
-{
-  "$schema": "node_modules/wrangler/config-schema.json",
-  "main": ".open-next/worker.js",
-  "name": "next-ai-draw-io-worker",
-  "compatibility_date": "2025-12-08",
-  "compatibility_flags": ["nodejs_compat", "global_fetch_strictly_public"],
-  "assets": {
-    "directory": ".open-next/assets",
-    "binding": "ASSETS"
-  },
-  "services": [
-    {
-      "binding": "WORKER_SELF_REFERENCE",
-      "service": "next-ai-draw-io-worker"
-    }
-  ]
-}
-```
-
-Skip to **Step 4**.
-
----
-
-### Option B: Deploy WITH R2 (Full ISR Support)
-
-R2 enables **Incremental Static Regeneration (ISR)** caching. Requires a payment method on your Cloudflare account.
-
-**1. Create an R2 bucket** in the Cloudflare Dashboard:
-
-- Go to **Storage & Databases → R2**
-- Click **Create bucket**
-- Name it: `next-inc-cache`
-
-**2. Configure `open-next.config.ts`:**
-
-```ts
-import { defineCloudflareConfig } from "@opennextjs/cloudflare/config"
-import r2IncrementalCache from "@opennextjs/cloudflare/overrides/incremental-cache/r2-incremental-cache"
-
-export default defineCloudflareConfig({
-  incrementalCache: r2IncrementalCache,
-})
-```
-
-**3. Configure `wrangler.jsonc` (with R2):**
-
-```jsonc
-{
-  "$schema": "node_modules/wrangler/config-schema.json",
-  "main": ".open-next/worker.js",
-  "name": "next-ai-draw-io-worker",
-  "compatibility_date": "2025-12-08",
-  "compatibility_flags": ["nodejs_compat", "global_fetch_strictly_public"],
-  "assets": {
-    "directory": ".open-next/assets",
-    "binding": "ASSETS"
-  },
-  "r2_buckets": [
-    {
-      "binding": "NEXT_INC_CACHE_R2_BUCKET",
-      "bucket_name": "next-inc-cache"
-    }
-  ],
-  "services": [
-    {
-      "binding": "WORKER_SELF_REFERENCE",
-      "service": "next-ai-draw-io-worker"
-    }
-  ]
-}
-```
-
-> **Important:** The `bucket_name` must exactly match the name you created in the Cloudflare dashboard.
-
----
-
-## Step 4 — Register a workers.dev subdomain (first-time only)
-
-Before your first deployment, you need a workers.dev subdomain.
-
-**Option 1: Via Cloudflare Dashboard (Recommended)**
-
-Visit: https://dash.cloudflare.com → Workers & Pages → Overview → Set up a subdomain
-
-**Option 2: During deploy**
-
-When you run `npm run deploy`, Wrangler may prompt:
-
-```
-Would you like to register a workers.dev subdomain? (Y/n)
-```
-
-Type `Y` and choose a subdomain name.
-
-> **Note:** In CI/CD or non-interactive environments, the prompt won't appear. Register via the dashboard first.
-
----
-
-## Step 5 — Deploy to Cloudflare
-
-```bash
-npm run deploy
-```
-
-What the script does:
-
-- Builds the Next.js app
-- Converts it to a Cloudflare Worker via OpenNext
-- Uploads static assets
-- Publishes the Worker
-
-Your app will be available at:
-
-```
-https://<worker-name>.<your-subdomain>.workers.dev
-```
-
----
-
-## Common issues & fixes
-
-### `You need to register a workers.dev subdomain`
-
-**Cause:** No workers.dev subdomain registered for your account.
-
-**Fix:** Go to https://dash.cloudflare.com → Workers & Pages → Set up a subdomain.
-
----
-
-### `Please enable R2 through the Cloudflare Dashboard`
-
-**Cause:** R2 is configured in wrangler.jsonc but not enabled on your account.
-
-**Fix:** Either enable R2 (requires payment method) or use Option A (deploy without R2).
-
----
-
-### `No R2 binding "NEXT_INC_CACHE_R2_BUCKET" found`
-
-**Cause:** `r2_buckets` is missing from `wrangler.jsonc`.
-
-**Fix:** Add the `r2_buckets` section or switch to Option A (without R2).
-
----
-
-### `Can't set compatibility date in the future`
-
-**Cause:** `compatibility_date` in wrangler config is set to a future date.
-
-**Fix:** Change `compatibility_date` to today or an earlier date.
-
----
-
-### Windows error: `resvg.wasm?module` (ENOENT)
-
-**Cause:** Windows filenames cannot include `?`, but a wasm asset uses `?module` in its filename.
-
-**Fix:** Build/deploy on Linux (WSL, Codespaces, or CI).
-
----
-
-## Optional: Preview locally
-
-Preview the Worker locally before deploying:
-
-```bash
-npm run preview
-```
-
----
-

-# 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` |
-
-**Do NOT use** internal Docker aliases like `http://drawio:8080`; the browser cannot resolve them.
