// Production setup with full monitoring
const integration = quickSetup.production();

// Custom configuration
const integration = createAgentAPIIntegration({
  agentAPI: {
    baseURL: 'http://localhost:3284',
    timeout: 30000,
    maxRetries: 3
  },
  workspace: {
    basePath: '/tmp/workspace',
    maxConcurrent: 10,
    cleanupAfter: 3600000
  },
  monitoring: {
    healthCheckInterval: 30000,
    alertThresholds: {
      errorRate: 10,
      responseTime: 5000
    }
  }
});

📊 Performance Criteria

• Response Time: < 5 seconds for simple operations
• Throughput: Support 10+ concurrent agent sessions
• Reliability: 99% success rate for agent communication
• Recovery: Automatic retry on transient failures

🧪 Testing

Comprehensive test suite with >90% coverage:

# Run AgentAPI integration tests
npm run agentapi:test

# Run examples
npm run agentapi:example

📚 Usage Examples

Basic Task Execution

import { createAgentAPIIntegration } from './src/integrations/index.js';

const integration = createAgentAPIIntegration();

const task = {
  id: 'feature-001',
  title: 'Add input validation',
  description: 'Implement comprehensive input validation',
  type: 'feature',
  requirements: ['Validate email format', 'Check password strength']
};

const result = await integration.executeTask(task);
console.log('Task completed:', result.parsedResults.summary);

Health Monitoring

import { AgentMonitor } from './src/integrations/index.js';

const monitor = new AgentMonitor();
monitor.on('health:alerts', (alerts) => {
  alerts.forEach(alert => console.log(`🚨 ${alert.message}`));
});
monitor.start();

Workspace Management

import { WorkspaceManager } from './src/integrations/index.js';

const workspaceManager = new WorkspaceManager();
const workspace = await workspaceManager.createWorkspace('task-001', {
  repository: 'https://github.com/example/project.git',
  environment: {
    dependencies: { nodePackages: ['lodash', 'axios'] }
  }
});

🛡️ Error Handling

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • Open a follow-up GitHub issue for this discussion.
