+   ```
+
+   If you want to publish a beta version:
+   ```bash
+   npm publish --tag beta
+   ```
+
+2. Verify the package is published:
+   ```bash
+   npm view homeassistant-mcp
+   ```
+
+## After Publishing
+
+1. Create a git tag for the version:
+   ```bash
+   git tag -a v1.0.0 -m "Version 1.0.0"
+   git push origin v1.0.0
+   ```
+
+2. Create a GitHub release with the same version number and include the changelog.
+
+## Testing the Published Package
+
+To test the published package:
+
+```bash
+# Install globally
+npm install -g homeassistant-mcp
+

+homeassistant-mcp
+
+# Or use npx without installing
+npx homeassistant-mcp
+```
+
+## Unpublishing
+
+If you need to unpublish a version (only possible within 72 hours of publishing):
+
+```bash
+npm unpublish homeassistant-mcp@1.0.0
+```
+
+## Publishing a New Version
+
+1. Update the version in package.json
+2. Update CHANGELOG.md
+3. Build all files
+4. Run tests
+5. Publish to npm
+6. Create a git tag
+7. Create a GitHub release

----
+## Overview
+
+The Model Context Protocol (MCP) server acts as a bridge between AI models (like Claude, GPT, etc.) and Home Assistant, enabling AI assistants to:
+
+- Execute commands on Home Assistant devices
+- Retrieve information about the smart home
+- Stream responses for long-running operations
+- Validate parameters and inputs
+- Provide consistent error handling
+
+## Features
+
+- **Modular Architecture** - Clean separation between transport, middleware, and tools
+- **Typed Interface** - Fully TypeScript typed for better developer experience
+- **Multiple Transports**:
+  - **Standard I/O** (stdin/stdout) for CLI integration
+  - **HTTP/REST API** with Server-Sent Events support for streaming
+- **Middleware System** - Validation, logging, timeout, and error handling
+- **Built-in Tools**:
+  - Light control (brightness, color, etc.)
+  - Climate control (thermostats, HVAC)
+  - More to come...
+- **Extensible Plugin System** - Easily add new tools and capabilities
+- **Streaming Responses** - Support for long-running operations
+- **Parameter Validation** - Using Zod schemas
+- **Claude & Cursor Integration** - Ready-made utilities for AI assistants
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js 16+
+- Home Assistant instance (or you can use the mock implementations for testing)
+
+### Installation
+
+```bash
+# Clone the repository
+cd /data
+git clone https://git.carriere.cloud/alex/homeassistant-mcp.git
+
+# Install dependencies 
+cd homeassistant-mcp
+
+npm install -g bun
+bun install
+
+# Build the project
+npm run build
+
+```
+
+### Running the Server
+
+```bash
+# Start with standard I/O transport (for AI assistant integration)
+npm start -- --stdio
+
+# Start with HTTP transport (for API access)
+npm start -- --http
+
+# Start with both transports
+npm start -- --stdio --http
+```
+
+### Configuration
+
+Configure the server using environment variables or a `.env` file:
+
+```dotenv
+# Server configuration
+PORT=3000
+NODE_ENV=development
+
+# Execution settings
+EXECUTION_TIMEOUT=30000
+STREAMING_ENABLED=true
+
+# Transport settings
+USE_STDIO_TRANSPORT=true
+USE_HTTP_TRANSPORT=true
+
+# Debug and logging
+DEBUG_MODE=false
+DEBUG_STDIO=false
+DEBUG_HTTP=false
+SILENT_STARTUP=false
+
+# CORS settings
+CORS_ORIGIN=*
+```
+
+## Architecture
+
+The MCP server is built with a layered architecture:
+
+1. **Transport Layer** - Handles communication protocols (stdio, HTTP)
+2. **Middleware Layer** - Processes requests through a pipeline
+3. **Tool Layer** - Implements specific functionality
+4. **Resource Layer** - Manages stateful resources
+
+### Tools
+
+Tools are the primary way to add functionality to the MCP server. Each tool:
+
+- Has a unique name
+- Accepts typed parameters
+- Returns typed results
+- Can stream partial results
+- Validates inputs and outputs
+
+Example tool registration:
+
+```typescript
+import { LightsControlTool } from "./tools/homeassistant/lights.tool.js";
+import { ClimateControlTool } from "./tools/homeassistant/climate.tool.js";
+
+// Register tools
+server.registerTool(new LightsControlTool());
+server.registerTool(new ClimateControlTool());
+```
+
+### API
+
+When running with HTTP transport, the server provides a JSON-RPC 2.0 API:
+
+- `POST /api/mcp/jsonrpc` - Execute a tool
+- `GET /api/mcp/stream` - Connect to SSE stream for real-time updates
+- `GET /api/mcp/info` - Get server information
+- `GET /health` - Health check endpoint
+
+## Integration with AI Models
+
+### Claude Integration
+
+```typescript
+import { createClaudeToolDefinitions } from "./mcp/index.js";
+
+// Generate Claude-compatible tool definitions
+const claudeTools = createClaudeToolDefinitions([
+  new LightsControlTool(),
+  new ClimateControlTool()
+]);
+
+// Use with Claude API
+const messages = [
+  { role: "user", content: "Turn on the lights in the living room" }
+];
+
+const response = await claude.messages.create({
+  model: "claude-3-opus-20240229",
+  messages,
+  tools: claudeTools
+});
+```
+
+### Cursor Integration
+
+To use the Home Assistant MCP server with Cursor, add the following to your `.cursor/config/config.json` file:
+
+```json
+{
+  "mcpServers": {
+    "homeassistant-mcp": {
+      "command": "bash",
+      "args": ["-c", "cd ${workspaceRoot} && bun run dist/index.js --stdio 2>/dev/null | grep -E '\\{\"jsonrpc\":\"2\\.0\"'"],
+      "env": {
+        "NODE_ENV": "development",
+        "USE_STDIO_TRANSPORT": "true",
+        "DEBUG_STDIO": "true"
+      }
+    }
+  }
+}
+```
+
+This configuration:
+1. Runs the MCP server with stdio transport
+2. Redirects all stderr output to /dev/null
+3. Uses grep to filter stdout for lines containing `{"jsonrpc":"2.0"`, ensuring clean JSON-RPC output
+
+#### Troubleshooting Cursor Integration
+
+If you encounter a "failed to create client" error when using the MCP server with Cursor:
+
+1. Make sure you're using the correct command and arguments in your Cursor configuration
+   - The bash script approach ensures only valid JSON-RPC messages reach Cursor
+   - Ensure the server is built by running `bun run build` before trying to connect
+
+2. Ensure the server is properly outputting JSON-RPC messages to stdout:
+   ```bash
+   bun run dist/index.js --stdio 2>/dev/null | grep -E '\{"jsonrpc":"2\.0"' > json_only.txt
+   ```
+   Then examine json_only.txt to verify it contains only valid JSON-RPC messages.
+
+3. Make sure grep is installed on your system (it should be available by default on most systems)
+
+4. Try rebuilding the server with:
+   ```bash
+   bun run build
+   ```
+   
+5. Enable debug mode by setting `DEBUG_STDIO=true` in the environment variables
+
+If the issue persists, you can try:
+1. Restarting Cursor
+2. Clearing Cursor's cache (Help > Developer > Clear Cache and Reload)
+3. Using a similar approach with Node.js:
+   ```json
+   {
+     "command": "bash",
+     "args": ["-c", "cd ${workspaceRoot} && node dist/index.js --stdio 2>/dev/null | grep -E '\\{\"jsonrpc\":\"2\\.0\"'"]
+   }
+   ```

+     "mcpServers": {
+       "homeassistant-mcp": {
+         "command": "npx",
+         "args": ["homeassistant-mcp"],
+         "env": {

+         }
+       }
+     }
+   }
+   ```
+
+3. Restart Claude Desktop.
+
+4. In Claude, you can now use the Home Assistant MCP tools.
+
+### JSON-RPC 2.0 Message Format
+
+## Usage
+
+### Using NPX (Easiest)
+
+The simplest way to use the Home Assistant MCP server is through NPX:
+
+```bash
+# Start the server in stdio mode
+npx homeassistant-mcp
+```
+
+This will automatically:
+1. Start the server in stdio mode
+2. Output JSON-RPC messages to stdout
+3. Send log messages to stderr
+4. Create a logs directory if it doesn't exist
+
+You can redirect stderr to hide logs and only see the JSON-RPC output:
+
+```bash
+npx homeassistant-mcp 2>/dev/null
+```
+
+### Manual Installation
+
+If you prefer to install the package globally or locally:
+
+```bash
+# Install globally
+npm install -g homeassistant-mcp
+
+# Then run
+homeassistant-mcp
+```
+
+Or install locally:
+
+```bash
+# Install locally
+npm install homeassistant-mcp
+
+# Then run using npx
+npx homeassistant-mcp
+```
+

-![API Version](https://img.shields.io/badge/API-v2.1-blueviolet) ![Rate Limit](https://img.shields.io/badge/Rate%20Limit-100%2Fmin-brightgreen)
-
-## 🌟 Quick Start
-
-```bash
-# Get API schema with caching
-curl -X GET http://localhost:3000/mcp \
-  -H "Cache-Control: max-age=3600" # Cache for 1 hour
-```
-
-## 🔌 Core Functions ⚙️
-
-### State Management (`/api/state`)
-```http
-GET /api/state?cache=true  # Enable client-side caching
-POST /api/state
-```
-
-**Example Request:**
-```json
-{
-  "context": "living_room",
-  "state": {
-    "lights": "on",
-    "temperature": 22
-  },
-  "_cache": {  // Optional caching config
-    "ttl": 300,  // 5 minutes
-    "tags": ["lights", "climate"]
-  }
-}
-```
-
-## ⚡ Action Endpoints
-
-### Execute Action with Cache Validation
-```http
-POST /api/action
-If-None-Match: "etag_value"  // Prevent duplicate actions
-```
-
-**Batch Processing:**
-```json
-{
-  "actions": [
-    { "action": "🌞 Morning Routine", "params": { "brightness": 80 } },
-    { "action": "❄️ AC Control", "params": { "temp": 21 } }
-  ],
-  "_parallel": true  // Execute actions concurrently
-}
-```
-
-## 🔍 Query Functions
-
-### Available Actions with ETag
-```http
-GET /api/actions
-ETag: "a1b2c3d4"  // Client-side cache validation
-```
-
-**Response Headers:**
-```
-Cache-Control: public, max-age=86400  // 24-hour cache
-ETag: "a1b2c3d4"
-```
-
-## 🌐 WebSocket Events
-
-```javascript
-const ws = new WebSocket('wss://ha-mcp/ws');
-ws.onmessage = ({ data }) => {
-  const event = JSON.parse(data);
-  if(event.type === 'STATE_UPDATE') {
-    updateUI(event.payload);  // 🎨 Real-time UI sync
-  }
-};
-```
-
-## 🗃️ Caching Strategies
-
-### Client-Side Caching
-```http
-GET /api/devices
-Cache-Control: max-age=300, stale-while-revalidate=60
-```
-
-### Server-Side Cache-Control
-```typescript
-// Example middleware configuration
-app.use(
-  cacheMiddleware({
-    ttl: 60 * 5,  // 5 minutes
-    paths: ['/api/devices', '/mcp'],
-    vary: ['Authorization']  // User-specific caching
-  })
-);
-```
-
-## ❌ Error Handling
-
-**429 Too Many Requests:**
-```json
-{
-  "error": {
-    "code": "RATE_LIMITED",
-    "message": "Slow down! 🐢",
-    "retry_after": 30,
-    "docs": "https://ha-mcp/docs/rate-limits"
-  }
-}
-```
-
-## 🚦 Rate Limiting Tiers
-
-| Tier          | Requests/min | Features               |
-|---------------|--------------|------------------------|
-| Guest         | 10           | Basic read-only        |
-| User          | 100          | Full access            |
-| Power User    | 500          | Priority queue         |
-| Integration   | 1000         | Bulk operations        |
-
-## 🛠️ Example Usage
-
-### Smart Cache Refresh
-```javascript
-async function getDevices() {
-  const response = await fetch('/api/devices', {
-    headers: {
-      'If-None-Match': localStorage.getItem('devicesETag')
-    }
-  });
-  
-  if(response.status === 304) {  // Not Modified
-    return JSON.parse(localStorage.devicesCache);
-  }
-  
-  const data = await response.json();
-  localStorage.setItem('devicesETag', response.headers.get('ETag'));
-  localStorage.setItem('devicesCache', JSON.stringify(data));
-  return data;
-}
-```
-
-## 🔒 Security Middleware (Enhanced)
-
-### Cache-Aware Rate Limiting
-```typescript
-app.use(
-  rateLimit({
-    windowMs: 15 * 60 * 1000, // 15 minutes
-    max: 100, // Limit each IP to 100 requests per window
-    cache: new RedisStore(), // Distributed cache
-    keyGenerator: (req) => {
-      return `${req.ip}-${req.headers.authorization}`;
-    }
-  })
-);
-```
-
-### Security Headers
-```http
-Content-Security-Policy: default-src 'self';
-Strict-Transport-Security: max-age=31536000;
-X-Content-Type-Options: nosniff;
-Cache-Control: public, max-age=600;
-ETag: "abc123"
-```
-
-## 📘 Best Practices
-
-1. **Cache Wisely:** Use `ETag` and `Cache-Control` headers for state data
-2. **Batch Operations:** Combine requests using `/api/actions/batch`
-3. **WebSocket First:** Prefer real-time updates over polling
-4. **Error Recovery:** Implement exponential backoff with jitter
-5. **Cache Invalidation:** Use tags for bulk invalidation
-
-```mermaid
-graph LR
-A[Client] -->|Cached Request| B{CDN}
-B -->|Cache Hit| C[Return 304]
-B -->|Cache Miss| D[Origin Server]
-D -->|Response| B
-B -->|Response| A
-```
-
-> Pro Tip: Use `curl -I` to inspect cache headers! 🔍
-
-## Device Control
-
-### Common Entity Controls
-
-```json
-{
-  "tool": "control",
-  "command": "turn_on",  // Options: "turn_on", "turn_off", "toggle"
-  "entity_id": "light.living_room"
-}
-```
-
-### Light Control
-
-```json
-{
-  "tool": "control",
-  "command": "turn_on",
-  "entity_id": "light.living_room",
-  "brightness": 128,
-  "color_temp": 4000,
-  "rgb_color": [255, 0, 0]
-}
-```
-
-## Add-on Management

-```json
-{
-  "tool": "addon",
-  "action": "install",
-  "slug": "core_configurator",
-  "version": "5.6.0"
-}
-```
-
-### Manage Add-on State
-
-```json
-{
-  "tool": "addon",
-  "action": "start",  // Options: "start", "stop", "restart"
-  "slug": "core_configurator"
-}
-```
-
-## Package Management

-- Apply proper security headers.
-- Gracefully handle errors based on the environment.
-
-## Troubleshooting
-
-If you experience issues with the API:
-- Verify the endpoint and request payload.
-- Check authentication tokens and required headers.
-- Consult the [Troubleshooting Guide](troubleshooting.md) for further guidance.
-
-## MCP Schema Endpoint
-
-The server exposes an MCP (Model Context Protocol) schema endpoint that describes all available tools and their parameters:
-
-```http
-GET /mcp
-```
-
-This endpoint returns a JSON schema describing all available tools, their parameters, and documentation resources. The schema follows the MCP specification and can be used by LLM clients to understand the server's capabilities.
-
-Example response:
-```json
-{
-  "tools": [
-    {
-      "name": "list_devices",
-      "description": "List all devices connected to Home Assistant",
-      "parameters": {
-        "type": "object",
-        "properties": {
-          "domain": {
-            "type": "string",
-            "enum": ["light", "climate", "alarm_control_panel", ...]
-          },
-          "area": { "type": "string" },
-          "floor": { "type": "string" }
-        }
-      }
-    },
-    // ... other tools
-  ],
-  "prompts": [],
-  "resources": [
-    {
-      "name": "Home Assistant API",
-      "url": "https://developers.home-assistant.io/docs/api/rest/"
-    }
-  ]
-}
-```
-
-Note: The `/mcp` endpoint is publicly accessible and does not require authentication, as it only provides schema information.
-

-
-Manages rate limiting for IP addresses to prevent abuse.
-
-**Parameters**:
-- `ip`: IP address to track
-- `maxRequests`: Maximum number of requests allowed (default: 100)
-- `windowMs`: Time window for rate limiting (default: 15 minutes)
-
-**Returns**: `boolean` or throws an error if limit is exceeded
-
-**Example**:
-```typescript
-try {
-  checkRateLimit('127.0.0.1'); // Checks rate limit with default settings
-} catch (error) {
-  // Handle rate limit exceeded
-}
-```
-
-#### `validateRequestHeaders(request: Request, requiredContentType?: string)`
-
-Validates incoming HTTP request headers for security and compliance.
-
-**Parameters**:
-- `request`: The incoming HTTP request
-- `requiredContentType`: Expected content type (default: 'application/json')
-
-**Checks**:
-- Content type
-- Request body size
-- Authorization header (optional)
-
-**Example**:
-```typescript
-try {
-  validateRequestHeaders(request);
-} catch (error) {
-  // Handle validation errors
-}
-```
-
-#### `sanitizeValue(value: unknown)`
-
-Sanitizes input values to prevent XSS attacks.
-
-**Features**:
-- Escapes HTML tags
-- Handles nested objects and arrays
-- Preserves non-string values
-
-**Example**:
-```typescript
-const sanitized = sanitizeValue('<script>alert("xss")</script>');
-// Returns: '&lt;script&gt;alert(&quot;xss&quot;)&lt;/script&gt;'
-```
-
-#### `applySecurityHeaders(request: Request, helmetConfig?: HelmetOptions)`
-
-Applies security headers to HTTP requests using Helmet.
-
-**Security Headers**:
-- Content Security Policy
-- X-Frame-Options
-- X-Content-Type-Options
-- Referrer Policy
-- HSTS (in production)
-
-**Example**:
-```typescript
-const headers = applySecurityHeaders(request);
-```
-
-#### `handleError(error: Error, env?: string)`
-
-Handles error responses with environment-specific details.
-
-**Modes**:
-- Production: Generic error message
-- Development: Detailed error with stack trace
-
-**Example**:
-```typescript
-const errorResponse = handleError(error, process.env.NODE_ENV);
-```
-
-### Middleware Usage

-- Clients should handle reconnection on connection loss
-
-## Example Implementation
-
-```javascript
-class HomeAssistantSSE {
-  constructor(baseUrl, token) {
-    this.baseUrl = baseUrl;
-    this.token = token;
-    this.eventSource = null;
-    this.reconnectAttempts = 0;
-    this.maxReconnectAttempts = 5;
-    this.reconnectDelay = 1000;
-  }
-
-  connect(options = {}) {
-    const params = new URLSearchParams({
-      token: this.token,
-      ...(options.events && { events: options.events.join(',') }),
-      ...(options.entity_id && { entity_id: options.entity_id }),
-      ...(options.domain && { domain: options.domain })
-    });
-
-    this.eventSource = new EventSource(`${this.baseUrl}/subscribe_events?${params}`);
-
-    this.eventSource.onmessage = (event) => {
-      const data = JSON.parse(event.data);
-      this.handleEvent(data);
-    };
-
-    this.eventSource.onerror = (error) => {
-      console.error('SSE Error:', error);
-      this.handleError(error);
-    };
-  }
-
-  handleEvent(data) {
-    switch (data.type) {
-      case 'connection':
-        this.reconnectAttempts = 0;
-        console.log('Connected:', data);
-        break;
-      case 'ping':
-        // Connection is alive
-        break;
-      case 'error':
-        console.error('Server Error:', data);
-        break;
-      default:
-        // Handle other event types
-        console.log('Event:', data);
-    }
-  }
-
-  handleError(error) {
-    this.eventSource?.close();
-    
-    if (this.reconnectAttempts < this.maxReconnectAttempts) {
-      this.reconnectAttempts++;
-      const delay = this.reconnectDelay * Math.pow(2, this.reconnectAttempts - 1);
-      console.log(`Reconnecting in ${delay}ms (attempt ${this.reconnectAttempts})`);
-      setTimeout(() => this.connect(), delay);
-    } else {
-      console.error('Max reconnection attempts reached');
-    }
-  }
-
-  disconnect() {
-    this.eventSource?.close();
-    this.eventSource = null;
-  }
-}
-
-// Usage example
-const client = new HomeAssistantSSE('http://localhost:3000', 'YOUR_HASS_TOKEN');
-client.connect({
-  events: ['state_changed', 'automation_triggered'],
-  domain: 'light'
-});
-```
-
-## Best Practices
-
-1. **Error Handling**
-   - Implement exponential backoff for reconnection attempts
-   - Handle connection timeouts gracefully
-   - Monitor for rate limit errors
-
-2. **Resource Management**
-   - Close EventSource when no longer needed
-   - Limit subscriptions to necessary events/entities
-   - Handle cleanup on page unload
-
-3. **Security**
-   - Never expose the authentication token in client-side code
-   - Use HTTPS in production
-   - Validate all incoming data
-
-4. **Performance**
-   - Subscribe only to needed events
-   - Implement client-side event filtering
-   - Monitor memory usage for long-running connections
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Connection Failures**
-   - Verify your authentication token is valid
-   - Check server URL is accessible
-   - Ensure proper network connectivity
-   - Verify SSL/TLS configuration if using HTTPS
-
-2. **Missing Events**
-   - Confirm subscription parameters are correct
-   - Check rate limiting status
-   - Verify entity/domain exists
-   - Monitor client-side event handlers
-
-3. **Performance Issues**
-   - Reduce number of subscriptions
-   - Implement client-side filtering
-   - Monitor memory usage
-   - Check network latency
-
-### Debugging Tips
-
-1. Enable console logging:
-```javascript
-const client = new HomeAssistantSSE('http://localhost:3000', 'YOUR_HASS_TOKEN');
-client.debug = true; // Enables detailed logging
-```
-
-2. Monitor network traffic:
-```javascript
-// Add event listeners for connection states
-eventSource.addEventListener('open', () => {
-  console.log('Connection opened');
-});
-
-eventSource.addEventListener('error', (e) => {
-  console.log('Connection error:', e);
-});
-```
-
-3. Track subscription status:
-```javascript
-// Get current subscriptions
-const stats = await fetch('/get_sse_stats', {
-  headers: { 'Authorization': `Bearer ${token}` }
-}).then(r => r.json());
-
-console.log('Current subscriptions:', stats);
-```

-```
-
-## Overview
-
-This document describes the testing setup and practices used in the Home Assistant MCP project. We use Bun's test runner for both unit and integration testing, ensuring comprehensive coverage across modules.
-
-## Test Structure
-
-Tests are organized in two main locations:
-
-1. **Root Level Integration Tests** (`/__tests__/`):
-
-```
-__tests__/
-├── ai/              # AI/ML component tests
-├── api/             # API integration tests
-├── context/         # Context management tests
-├── hass/            # Home Assistant integration tests
-├── schemas/         # Schema validation tests
-├── security/        # Security integration tests
-├── tools/           # Tools and utilities tests
-├── websocket/       # WebSocket integration tests
-├── helpers.test.ts  # Helper function tests
-├── index.test.ts    # Main application tests
-└── server.test.ts   # Server integration tests
-```
-
-2. **Component Level Unit Tests** (`src/**/`):
-
-```
-src/
-├── __tests__/   # Global test setup and utilities
-│   └── setup.ts # Global test configuration
-├── component/
-│   ├── __tests__/   # Component-specific unit tests
-│   └── component.ts
-```
-
-## Test Configuration
-
-### Bun Test Configuration (`bunfig.toml`)
-
-```toml
-[test]
-preload = ["./src/__tests__/setup.ts"]  # Global test setup
-coverage = true                         # Enable coverage by default
-timeout = 30000                         # Test timeout in milliseconds
-testMatch = ["**/__tests__/**/*.test.ts"] # Test file patterns
-```
-
-### Bun Scripts
-
-Available test commands in `package.json`:
-
-```bash
-# Run all tests
-bun test
-
-# Watch mode for development
-bun test --watch
-
-# Generate coverage report
-bun test --coverage
-
-# Run linting
-bun run lint
-
-# Format code
-bun run format
-```
-
-## Test Setup
-
-### Global Configuration
-
-A global test setup file (`src/__tests__/setup.ts`) provides:
-- Environment configuration
-- Mock utilities
-- Test helper functions
-- Global lifecycle hooks
-
-### Test Environment
-
-- Environment variables are loaded from `.env.test`.
-- Console output is minimized unless `DEBUG=true`.
-- JWT secrets and tokens are preconfigured for testing.
-- Rate limiting and security features are initialized appropriately.
-
-## Running Tests
-
-```bash
-# Basic test run
-bun test
-
-# Run tests with coverage
-bun test --coverage
-
-# Run a specific test file
-bun test path/to/test.test.ts
-
-# Run tests in watch mode
-bun test --watch
-
-# Run tests with debug output
-DEBUG=true bun test
-
-# Run tests with increased timeout
-bun test --timeout 60000
-
-# Run tests matching a pattern
-bun test --pattern "auth"
-```
-
-## Advanced Debugging
-
-### Using Node Inspector
-
-```bash
-# Start tests with inspector
-bun test --inspect
-
-# Start tests with inspector and break on first line
-bun test --inspect-brk
-```
-
-### Using VS Code
-
-Create a launch configuration in `.vscode/launch.json`:
-
-```json
-{
-  "version": "0.2.0",
-  "configurations": [
-    {
-      "type": "bun",
-      "request": "launch",
-      "name": "Debug Tests",
-      "program": "${workspaceFolder}/node_modules/bun/bin/bun",
-      "args": ["test", "${file}"],
-      "cwd": "${workspaceFolder}",
-      "env": { "DEBUG": "true" }
-    }
-  ]
-}
-```
-
-### Test Isolation
-
-To run a single test in isolation:
-
-```typescript
-describe.only("specific test suite", () => {
-  it.only("specific test case", () => {
-    // Only this test will run
-  });
-});
-```
-
-## Writing Tests
-
-### Test File Naming
-
-- Place test files in a `__tests__` directory adjacent to the code being tested.
-- Name files with the pattern `*.test.ts`.
-- Mirror the structure of the source code in your test organization.
-
-### Example Test Structure
-
-```typescript
-describe("Security Features", () => {
-  it("should validate tokens correctly", () => {
-    const payload = { userId: "123", role: "user" };
-    const token = jwt.sign(payload, validSecret, { expiresIn: "1h" });
-    const result = TokenManager.validateToken(token, testIp);
-    expect(result.valid).toBe(true);
-  });
-});
-```
-
-## Coverage
-
-The project maintains strict coverage:
-- Overall coverage: at least 80%
-- Critical paths: 90%+
-- New features: ≥85% coverage
-
-Generate a coverage report with:
-
-```bash
-bun test --coverage
-```
-
-## Security Middleware Testing
-
-### Utility Function Testing
-
-The security middleware now uses a utility-first approach, which allows for more granular and comprehensive testing. Each security function is now independently testable, improving code reliability and maintainability.
-
-#### Key Utility Functions
-
-1. **Rate Limiting (`checkRateLimit`)**
-   - Tests multiple scenarios:
-     - Requests under threshold
-     - Requests exceeding threshold
-     - Rate limit reset after window expiration
-   
-   ```typescript
-   // Example test
-   it('should throw when requests exceed threshold', () => {
-     const ip = '127.0.0.2';
-     for (let i = 0; i < 11; i++) {
-       if (i < 10) {
-         expect(() => checkRateLimit(ip, 10)).not.toThrow();
-       } else {
-         expect(() => checkRateLimit(ip, 10)).toThrow('Too many requests from this IP');
-       }
-     }
-   });
-   ```
-
-2. **Request Validation (`validateRequestHeaders`)**
-   - Tests content type validation
-   - Checks request size limits
-   - Validates authorization headers
-   
-   ```typescript
-   it('should reject invalid content type', () => {
-     const mockRequest = new Request('http://localhost', {
-       method: 'POST',
-       headers: { 'content-type': 'text/plain' }
-     });
-     expect(() => validateRequestHeaders(mockRequest)).toThrow('Content-Type must be application/json');
-   });
-   ```
-
-3. **Input Sanitization (`sanitizeValue`)**
-   - Sanitizes HTML tags
-   - Handles nested objects
-   - Preserves non-string values
-   
-   ```typescript
-   it('should sanitize HTML tags', () => {
-     const input = '<script>alert("xss")</script>Hello';
-     const sanitized = sanitizeValue(input);
-     expect(sanitized).toBe('&lt;script&gt;alert(&quot;xss&quot;)&lt;/script&gt;Hello');
-   });
-   ```
-
-4. **Security Headers (`applySecurityHeaders`)**
-   - Verifies correct security header application
-   - Checks CSP, frame options, and other security headers
-   
-   ```typescript
-   it('should apply security headers', () => {
-     const mockRequest = new Request('http://localhost');
-     const headers = applySecurityHeaders(mockRequest);
-     expect(headers['content-security-policy']).toBeDefined();
-     expect(headers['x-frame-options']).toBeDefined();
-   });
-   ```
-
-5. **Error Handling (`handleError`)**
-   - Tests error responses in production and development modes
-   - Verifies error message and stack trace inclusion
-   
-   ```typescript
-   it('should include error details in development mode', () => {
-     const error = new Error('Test error');
-     const result = handleError(error, 'development');
-     expect(result).toEqual({
-       error: true,
-       message: 'Internal server error',
-       error: 'Test error',
-       stack: expect.any(String)
-     });
-   });
-   ```
-
-### Testing Philosophy
-
-- **Isolation**: Each utility function is tested independently
-- **Comprehensive Coverage**: Multiple scenarios for each function
-- **Predictable Behavior**: Clear expectations for input and output
-- **Error Handling**: Robust testing of error conditions
-
-### Best Practices
-
-1. Use minimal, focused test cases
-2. Test both successful and failure scenarios
-3. Verify input sanitization and security measures
-4. Mock external dependencies when necessary
-
-### Running Security Tests
-
-```bash
-# Run all tests
-bun test
-
-# Run specific security tests
-bun test __tests__/security/
-```
-
-### Continuous Improvement
-
-- Regularly update test cases
-- Add new test scenarios as security requirements evolve
-- Perform periodic security audits
-
-## Best Practices
-
-1. **Isolation**: Each test should be independent and not rely on the state of other tests.
-2. **Mocking**: Use the provided mock utilities for external dependencies.
-3. **Cleanup**: Clean up any resources or state modifications in `afterEach` or `afterAll` hooks.
-4. **Descriptive Names**: Use clear, descriptive test names that explain the expected behavior.
-5. **Assertions**: Make specific, meaningful assertions rather than general ones.
-6. **Setup**: Use `beforeEach` for common test setup to avoid repetition.
-7. **Error Cases**: Test both success and error cases for complete coverage.
-
-## Coverage
-
-The project aims for high test coverage, particularly focusing on:
-- Security-critical code paths
-- API endpoints
-- Data validation
-- Error handling
-- Event broadcasting
-
-Run coverage reports using:
-```bash
-bun test --coverage
-```
-
-## Debugging Tests
-
-To debug tests:
-1. Set `DEBUG=true` to enable console output during tests
-2. Use the `--watch` flag for development
-3. Add `console.log()` statements (they're only shown when DEBUG is true)
-4. Use the test utilities' debugging helpers
-
-### Advanced Debugging
-
-1. **Using Node Inspector**:
-   ```bash
-   # Start tests with inspector
-   bun test --inspect
-   
-   # Start tests with inspector and break on first line
-   bun test --inspect-brk
-   ```
-
-2. **Using VS Code**:
-   ```jsonc
-   // .vscode/launch.json
-   {
-     "version": "0.2.0",
-     "configurations": [
-       {
-         "type": "bun",
-         "request": "launch",
-         "name": "Debug Tests",
-         "program": "${workspaceFolder}/node_modules/bun/bin/bun",
-         "args": ["test", "${file}"],
-         "cwd": "${workspaceFolder}",
-         "env": { "DEBUG": "true" }
-       }
-     ]
-   }
-   ```
-
-3. **Test Isolation**:
-   To run a single test in isolation:
-   ```typescript
-   describe.only("specific test suite", () => {
-     it.only("specific test case", () => {
-       // Only this test will run
-     });
-   });
-   ```
-
-## Contributing
-
-When contributing new code:
-1. Add tests for new features
-2. Ensure existing tests pass
-3. Maintain or improve coverage
-4. Follow the existing test patterns and naming conventions
-5. Document any new test utilities or patterns 
-
-## Coverage Requirements
-
-The project maintains strict coverage requirements:
-
-- Minimum overall coverage: 80%
-- Critical paths (security, API, data validation): 90%
-- New features must include tests with >= 85% coverage
-
-Coverage reports are generated in multiple formats:
-- Console summary
-- HTML report (./coverage/index.html)
-- LCOV report (./coverage/lcov.info)
-
-To view detailed coverage:
-```bash
-# Generate and open coverage report
-bun test --coverage && open coverage/index.html
-```
