Provider Fallback System

Intelligent Failover

// Automatic provider switching based on:
interface ProviderSelection {
  primaryProvider: string;     // User's preferred provider
  fallbackChain: string[];     // Ordered fallback list
  healthCheck: boolean;        // Real-time availability
  rateLimit: RateLimitStatus;  // Current usage limits
  capabilities: string[];      // Feature compatibility
}

// Example fallback logic:
const providerChain = [
  'openai',      // Primary: Best for general tasks
  'claude',      // Fallback 1: Good for analysis
  'gemini',      // Fallback 2: Free tier available
  'chrome-ai'    // Final fallback: Always available
];

Provider Selection Criteria

• Availability: Real-time health checks
• Rate Limits: Avoid providers near limits
• Task Suitability: Match provider strengths to task type
• User Preferences: Respect user-defined priorities
• Cost Optimization: Consider API costs when applicable

Performance Optimization

Request Optimization

• Batch Processing: Combine related requests
• Caching: Store frequent responses locally
• Compression: Minimize payload sizes
• Streaming: Real-time response display

Rate Limit Management

class RateLimitManager {
  private limits: Map<string, RateLimit> = new Map();
  
  async checkAvailability(provider: string): Promise<boolean> {
    const limit = this.limits.get(provider);
    if (!limit) return true;
    
    return limit.remaining > 0 && 
           Date.now() > limit.resetTime;
  }
  
  updateLimits(provider: string, headers: Headers) {
    this.limits.set(provider, {
      remaining: parseInt(headers.get('x-ratelimit-remaining')),
      resetTime: parseInt(headers.get('x-ratelimit-reset')) * 1000
    });
  }
}

Privacy & Security

Privacy-First Architecture

Data Handling Principles

Local Processing Priority

• Chrome's built-in AI processes data locally when possible
• Content extraction and preprocessing done in-browser
• Only necessary data sent to external APIs
• Immediate cleanup of temporary data

Data Minimization

interface DataProcessingPolicy {
  contentLimit: 50000;        // Max characters sent to AI
  retentionPeriod: 0;         // No permanent storage
  personalDataFiltering: true; // Remove PII before processing
  encryptionInTransit: true;   // All API calls encrypted
}

// Example PII filtering
class PrivacyFilter {
  static sanitizeContent(content: string): string {
    return content
      .replace(/\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b/g, '[EMAIL]')
      .replace(/\b\d{3}-\d{2}-\d{4}\b/g, '[SSN]')
      .replace(/\b\d{4}[\s-]?\d{4}[\s-]?\d{4}[\s-]?\d{4}\b/g, '[CARD]');
  }
}

Security Measures

API Key Security

• API keys encrypted using Chrome's storage encryption
• Keys never logged or transmitted unnecessarily
• Secure key rotation supported
• Option to use session-only keys

Content Security

// Content Security Policy
const csp = {
  "script-src": "'self'",
  "object-src": "'self'",
  "connect-src": "'self' https://api.openai.com https://api.anthropic.com https://generativelanguage.googleapis.com",
  "img-src": "'self' data: https:"
};

// Input validation and sanitization
class SecurityValidator {
  static validateInput(input: string): boolean {
    const maxLength = 100000;
    const forbiddenPatterns = [
      /<script[^>]*>.*?<\/script>/gi,
      /javascript:/gi,
      /data:text\/html/gi
    ];
    
    return input.length <= maxLength && 
           !forbiddenPatterns.some(pattern => pattern.test(input));
  }
}

Network Security

• All external API calls use HTTPS/TLS 1.3
• Certificate pinning for critical endpoints
• Request signing and validation
• Protection against man-in-the-middle attacks

User Control & Transparency

Privacy Controls

• Incognito Mode: Automatic data isolation
• Data Export: Users can export all their data
• Data Deletion: Complete data removal on demand
• Processing Opt-out: Disable specific AI providers

Transparency Features

• Activity Log: See what data was processed when
• Provider Usage: Track which AI services were used
• Data Flow: Understand where information goes
• Settings Audit: Review all privacy configurations

Compliance Standards

• GDPR compliant data handling
• CCPA privacy rights respected
• No tracking or analytics without consent
• Open source for transparency and audit

Testing Strategy

Comprehensive Testing Approach

Unit Testing (Vitest)

// Example test structure
import { describe, it, expect, vi, beforeEach } from 'vitest';
import { ContentProcessor } from '../services/content-processor.js';

describe('ContentProcessor', () => {
  let processor: ContentProcessor;
  
  beforeEach(() => {
    processor = new ContentProcessor();
  });
  
  it('should extract clean text from HTML content', async () => {
    const htmlContent = '<p>Hello <strong>world</strong>!</p>';
    const result = await processor.extractText(htmlContent);
    
    expect(result).toBe('Hello world!');
  });
  
  it('should handle malformed HTML gracefully', async () => {
    const malformedHtml = '<p>Unclosed paragraph<div>Mixed tags';
    const result = await processor.extractText(malformedHtml);
    
    expect(result).toBeTruthy();
    expect(typeof result).toBe('string');
  });
});

E2E Testing (Playwright)

// Extension testing with Playwright
import { test, expect } from '@playwright/test';

test.describe('GenAI Extension', () => {
  test('should load extension popup', async ({ page }) => {
    // Load extension
    await page.goto('chrome://extensions/');
    
    // Navigate to test page
    await page.goto('https://example.com');
    
    // Click extension icon
    await page.click('[title="GenAI Browser Tool"]');
    
    // Verify popup loads
    await expect(page.locator('.genai-popup')).toBeVisible();
  });
  
  test('should summarize page content', async ({ page }) => {
    await page.goto('https://example.com/article');
    await page.click('[title="GenAI Browser Tool"]');
    await page.click('#summarize-button');
    
    // Wait for AI processing
    await expect(page.locator('.summary-result')).toBeVisible({ timeout: 10000 });
    
    const summaryText = await page.locator('.summary-result').textContent();
    expect(summaryText.length).toBeGreaterThan(10);
  });
});

Performance Testing

// Performance monitoring
class PerformanceMonitor {
  static async measureProcessingTime(operation: () => Promise<any>): Promise<number> {
    const start = performance.now();
    await operation();
    const end = performance.now();
    return end - start;
  }
  
  static measureMemoryUsage(): number {
    return (performance as any).memory?.usedJSHeapSize || 0;
  }
}

// Performance tests
it('should process content within performance thresholds', async () => {
  const processingTime = await PerformanceMonitor.measureProcessingTime(
    () => processor.summarize(longContent)
  );
  
  expect(processingTime).toBeLessThan(5000); // 5 seconds max
});

Troubleshooting

Common Issues & Solutions

Extension Not Loading

Symptoms: Extension icon not appearing, popup not opening

Solutions:

1. Check Browser Compatibility

   # Minimum versions supported
   Chrome >= 88
   Edge >= 88
   Firefox >= 78 (limited support)

2. Verify Installation

   • Open chrome://extensions/
   • Ensure extension is enabled
   • Check for error messages in red
   • Click "Reload" if needed

3. Clear Extension Data

   // In extension popup console
   chrome.storage.local.clear();
   chrome.storage.sync.clear();

4. Reinstall Extension

   • Remove extension from browser
   • Restart browser
   • Reinstall from store or load unpacked

AI Processing Issues

Symptoms: "Processing failed", slow responses, no AI output

Diagnostic Steps:

1. Check API Keys

   // Open extension popup > Settings
   // Verify API keys are correctly entered
   // Test each provider individually

2. Network Connectivity

   # Test API endpoints
   curl -X POST https://api.openai.com/v1/models \
     -H "Authorization: Bearer YOUR_API_KEY"

3. Rate Limit Status

   • Check provider dashboard for rate limits
   • Switch to different provider temporarily
   • Wait for rate limit reset

4. Content Size Issues

   // Reduce content length if too large
   const maxLength = 50000; // characters
   const truncatedContent = content.substring(0, maxLength);

Performance Issues

Symptoms: Slow responses, browser lag, high memory usage

Optimization Steps:

1. Reduce Processing Load

   // Settings > Performance
   {
     "maxConcurrentRequests": 1,
     "enableCaching": true,
     "streamingResponses": false
   }

2. Clear Cache

   // Extension popup > Settings > Clear Cache
   chrome.storage.local.remove(['cache', 'responses']);

3. Monitor Resource Usage

   // Check memory usage
   console.log('Memory:', performance.memory?.usedJSHeapSize || 'N/A');

4. Update Extension

   • Check for extension updates
   • Clear browser cache
   • Restart browser

Debug Mode

Enabling Debug Features

Enable Debug Mode

1. Open extension popup
2. Go to Settings > Advanced
3. Enable "Debug Mode"
4. Reload extension

Debug Console

// Access debug information
window.genaiDebug = {
  logs: [], // All extension logs
  performance: {}, // Performance metrics
  apiCalls: [], // API call history
  errors: [] // Error stack traces
};

// View recent activity
console.table(window.genaiDebug.apiCalls.slice(-10));

Performance Monitoring

// Built-in performance tracking
class DebugMonitor {
  static logPerformance(operation: string, duration: number) {
    console.log(`[PERFORMANCE] ${operation}: ${duration}ms`);
    
    if (duration > 5000) {
      console.warn(`Slow operation detected: ${operation}`);
    }
  }
}
