  MCPConnectionError 
} from 'planner-mcp/errors';

try {
  const plan = await orchestrator.createPlan(request);
} catch (error) {
  if (error instanceof ValidationError) {
    console.log('Validation failed:', error.validationResults);
  } else if (error instanceof MCPConnectionError) {
    console.log('MCP server unavailable:', error.serverName);
  } else {
    console.log('Unexpected error:', error.message);
  }
}
```

**Error Categories:**
- **ValidationError** - Plan validation failures
- **AuthenticationError** - Authentication/authorization failures
- **InfrastructureError** - System infrastructure issues
- **MCPConnectionError** - MCP server connectivity problems
- **ConfigurationError** - Configuration and setup issues

### Error Recovery

```typescript
import { ErrorRecoveryManager } from 'planner-mcp/recovery';

const recovery = new ErrorRecoveryManager({
  strategies: ['retry', 'fallback', 'circuit_breaker'],
  maxRetries: 3,
  backoff: 'exponential'
});
```

## Performance Guidelines

### Optimization Best Practices

1. **Use Caching Effectively**
   ```typescript
   // Cache frequently accessed data
   const cached = await cache.get(key) || await expensive_operation();
   ```

2. **Implement Circuit Breakers**
   ```typescript
   // Prevent cascade failures
   const circuitBreaker = new CircuitBreaker(service, {
     timeout: 3000,
     errorThresholdPercentage: 50
   });
   ```

3. **Monitor Performance Metrics**
   ```typescript
   // Track key performance indicators
   metrics.timing('plan.generation.duration', duration);
   metrics.increment('plan.generation.success');
   ```

### Performance Targets

| Metric | Target | Monitoring |
|--------|--------|------------|
| **Response Time (P95)** | < 2 seconds | Real-time |
| **Error Rate** | < 1% | Real-time |
| **Availability** | > 99.9% | 24/7 |
| **Throughput** | > 1000 req/min | Real-time |
| **Quality Score** | > 85 average | Daily |

## Configuration

### Environment Configuration
Comprehensive configuration management.

```typescript
import { ConfigManager } from 'planner-mcp/config';

const config = new ConfigManager({
  sources: ['env', 'file', 'vault'],
  validation: true,
  encryption: true
});

// Access configuration
const dbConfig = config.get('database');
const mcpServers = config.get('mcp.servers');
```

### Feature Flags
Dynamic feature management and A/B testing.

```typescript
import { FeatureFlags } from 'planner-mcp/features';

const features = new FeatureFlags({
  provider: 'launchdarkly',
  fallbacks: true
});

if (await features.isEnabled('enhanced-validation', userId)) {
  // Use enhanced validation
}
```
