## 🚀 Quick Start for AI Agents (Recommended Method)

### Step 1: Install UIBridge
```bash
npm install @sashbot/uibridge
```

### Step 2: Start the Server
```bash
# Start the UIBridge server (keep this running)
node node_modules/@sashbot/uibridge/api-server.cjs
```
**✅ Server Status**: You should see `UIBridge API Server running on http://localhost:3002`

### Step 3: Load PowerShell Helper Functions
```powershell
# Download the helper functions (includes JSON corruption fixes)
curl -o uibridge-powershell-helpers.ps1 https://unpkg.com/@sashbot/uibridge@latest/uibridge-powershell-helpers.ps1

# Load the functions (do this first in every session)
. .\uibridge-powershell-helpers.ps1
```

### Step 4: Verify Everything Works
```powershell
# Test server connection
Test-UIBridgeServer

# Start a complete automation session (opens browser and takes screenshot)
Start-UIBridgeSession -Url "https://example.com"
```

**🎉 That's it!** You now have reliable browser automation with proper error handling.

Click-UIBridgeElement -Selector "button[type='submit']"
```

### 📸 Screenshots (Auto-Saved with Validation)
```powershell
# Basic screenshot (recommended)
Take-UIBridgeScreenshot

# Full page screenshot with options
Take-UIBridgeScreenshot -FullPage $true -Format "png" -Quality 90

# Screenshot with specific background color
Take-UIBridgeScreenshot -BackgroundColor "white"

## ✅ Why PowerShell Helpers Are the Primary Method

### 🛡️ **Built-in Reliability** (v1.2.5+ includes JSON corruption fixes)
- **JSON Validation**: Every command validates JSON before sending to prevent corruption errors
- **Consistent Formatting**: All JSON uses proper depth and escaping
- **Error Handling**: Clear error messages with troubleshooting guidance
- **Special Character Support**: Handles quotes, apostrophes, unicode, emoji correctly

### 🎯 **AI Agent Optimized**
- **Simple Function Calls**: `Click-UIBridgeText -Text "Submit"` instead of complex JSON
- **Multiple Click Strategies**: Automatic fallback between text, testId, and CSS selectors
- **Auto-Save Screenshots**: Timestamps and organized file management
- **Connection Testing**: Built-in server health checks

### 🧪 **Comprehensive Testing**
- **17 Unit Tests**: JSON generation, special characters, error handling
- **Integration Tests**: Real server and browser testing
- **Regression Prevention**: Prevents the return of JSON corruption bugs

```powershell
# Run tests to verify everything works
pwsh -ExecutionPolicy Bypass -File test-powershell-helpers.ps1
```

## 🔧 When to Use Alternative Methods

The PowerShell helpers are the **recommended primary method**, but use alternatives for these specific scenarios:

### 🌐 Live Session Method (Visual Debugging)
**Use when**: You need to see automation happen in real-time in your own browser
```html
<!-- Add to your web app for live visual feedback -->
<script src="http://localhost:3002/uibridge-client.js"></script>
```
```powershell
# Download live session helpers
curl -o uibridge-live-session-helpers.ps1 https://unpkg.com/@sashbot/uibridge@latest/uibridge-live-session-helpers.ps1
. .\uibridge-live-session-helpers.ps1

# Control YOUR browser live
Click-UIBridgeLiveText -Text "Submit"  # You see it happen in your browser!
```

### 🔧 Direct HTTP API
**Use when**: 
- Working from non-PowerShell environments (Python, Node.js, etc.)
- Need custom JSON structures not supported by helpers
- Building your own wrapper functions

```bash
# Direct HTTP for other languages
curl -X POST http://localhost:3002/execute \
  -H "Content-Type: application/json" \
  -d '{"command":"click","selector":{"text":"Submit"}}'
```

### 📦 NPM Package Integration
**Use when**: Building JavaScript/TypeScript applications with UIBridge
```javascript
import { UIBridge } from '@sashbot/uibridge';
const bridge = new UIBridge();
await bridge.click({ text: 'Submit' });
```

## 🚨 Troubleshooting & Error Resolution

### Problem: JSON corruption errors
**✅ FIXED in v1.2.5+** 
The PowerShell helpers now generate valid JSON consistently:
```powershell
# Verify the fix works
pwsh -ExecutionPolicy Bypass -File test-powershell-helpers.ps1
# Should show: All tests passed! ✅
```

### Problem: Server not accessible
```powershell
Test-UIBridgeServer
# If this fails:
# 1. Restart server: node node_modules/@sashbot/uibridge/api-server.cjs
# 2. Check firewall/antivirus blocking port 3002
# 3. Try different port: . .\uibridge-powershell-helpers.ps1 -ServerUrl "http://localhost:3003"
```

### Problem: Elements not found
```powershell
# Try multiple strategies in order:
Click-UIBridgeText -Text "Button Text"        # Try this first (most reliable)
Click-UIBridgeTestId -TestId "button-id"      # If text doesn't work  
Click-UIBridgeElement -Selector "#button-id"  # If test ID doesn't work

# Take screenshot to see current page state
Take-UIBridgeScreenshot
```

### Problem: Special characters in text
```powershell
# These all work correctly with the fixed helpers:
Click-UIBridgeText -Text "Text with ""quotes"" and 'apostrophes'"
Click-UIBridgeText -Text "Button with emoji 🚀"
Click-UIBridgeText -Text "Unicode: 测试 العربية русский"
```

---

## 🎯 AI Agent Best Practices

### ✅ DO (Primary Method):
```powershell
# 1. Always load helpers first
. .\uibridge-powershell-helpers.ps1

# 2. Test connection before automating
Test-UIBridgeServer

# 3. Use text-based clicking first (most reliable)
Click-UIBridgeText -Text "Submit"

# 4. Take screenshots to verify actions
Take-UIBridgeScreenshot

# 5. Use complete workflows
Start-UIBridgeSession -Url "https://example.com"
```

### ⚠️ AVOID:
- Don't construct JSON manually - use the helper functions
- Don't skip `Test-UIBridgeServer` - always verify connection
- Don't use complex CSS selectors if text clicking works
- Don't forget to handle errors with try/catch blocks
