Orchestration Implementation Guide ​

Bridge from architectural specifications to working code. This guide provides reference implementations, development workflows, and practical examples for building orchestration layer components.

Quick Implementation Overview ​

30-Second Architecture Summary ​

User Query → CEO (Intent + Budget) → ACS (Provider Selection) → Execution → Results

5-Minute "Hello World" Pipeline ​

  1. Start CEO: Parse intent, allocate basic budget
  2. Route to ACS: Select single provider based on simple scoring
  3. Execute: Call provider, handle timeout/errors
  4. Return: Format results with metadata

Implementation Roadmap ​

Phase 1: Core Pipeline (v0) ​

  • [ ] CEO: Basic intent parsing + budget allocation
  • [ ] ACS: Simple provider selection + execution
  • [ ] Provider Interface: HTTP client with retry logic
  • [ ] Error Handling: Timeout, retry, fallback patterns

Phase 2: Advanced Features (v1) ​

  • [ ] CEO: Advanced cognitive load management
  • [ ] ACS: ML-based scoring models
  • [ ] HCS: Streaming coordination (removed from v0)
  • [ ] Monitoring: Comprehensive metrics and alerting

Development Workflows ​

Local Development Setup ​

bash
# 1. Clone and setup
git clone <repo>
cd orchestration
npm install

# 2. Start local services
docker-compose up -d  # Mock providers + monitoring

# 3. Run hello world
npm run dev:hello-world

# 4. Run tests
npm test

Testing Strategy ​

  • Unit Tests: Component isolation with mocks
  • Integration Tests: Full pipeline with test providers
  • Load Tests: Performance under realistic load
  • Chaos Tests: Failure scenarios and recovery

Debugging Workflow ​

  1. Enable Debug Logging: DEBUG=orchestration:* npm start
  2. Check Component Health: curl /health endpoints
  3. Trace Request Flow: Follow request ID through logs
  4. Validate Provider Responses: Check provider-specific logs

Common Implementation Patterns ​

Error Handling Pattern ​

typescript
async function executeWithRetry<T>(
  operation: () => Promise<T>,
  retries: number = 3,
  timeout: number = 5000
): Promise<T> {
  // Implementation example - see component guides
}

Configuration Management ​

typescript
interface OrchestrationConfig {
  ceo: CEOConfig;
  acs: ACSConfig;
  providers: ProviderConfig[];
  monitoring: MonitoringConfig;
}

Monitoring Integration ​

typescript
// Performance tracking
const metrics = new OrchestrationMetrics();
metrics.recordLatency('ceo.intent_parsing', duration);
metrics.incrementCounter('acs.provider_selection', {provider: 'openai'});

Production Deployment ​

Infrastructure Requirements ​

  • CPU: 2-4 cores per orchestration instance
  • Memory: 2-8GB depending on provider count
  • Network: Low-latency connection to providers
  • Storage: Minimal (stateless design)

Scaling Patterns ​

  • Horizontal: Multiple orchestration instances behind load balancer
  • Provider-based: Scale ACS instances per provider type
  • Geographic: Deploy close to user populations

Monitoring & Alerting ​

  • Request Success Rate: >99.5% uptime SLA
  • Response Latency: <500ms p95 end-to-end
  • Provider Health: Automatic failover on provider issues
  • Error Rates: Alert on >1% error rate per component

Getting Started Checklist ​

First 15 Minutes ​

  • [ ] Read this README
  • [ ] Run local development setup
  • [ ] Execute hello world example
  • [ ] Verify all tests pass

First Hour ​

  • [ ] Implement basic CEO intent parsing
  • [ ] Add simple ACS provider selection
  • [ ] Test full pipeline with mock provider
  • [ ] Add basic error handling

First Day ​

  • [ ] Connect to real provider (OpenAI/Anthropic)
  • [ ] Add comprehensive logging
  • [ ] Implement retry logic
  • [ ] Add basic metrics collection

First Week ​

  • [ ] Add multiple provider support
  • [ ] Implement budget management
  • [ ] Add integration tests
  • [ ] Deploy to staging environment

Troubleshooting Quick Reference ​

Common Issues ​

  1. Provider Timeouts: Check network connectivity and increase timeout values
  2. Budget Exhaustion: Review budget allocation algorithms
  3. Score Calculation Errors: Validate benefit/cost model inputs
  4. Memory Leaks: Check for unclosed connections and event listeners

Debug Commands ​

bash
# Component health checks
curl localhost:3000/health/ceo
curl localhost:3000/health/acs

# Provider connectivity
npm run debug:providers

# Full system status
npm run status:all

Performance Profiling ​

bash
# CPU profiling
npm run profile:cpu

# Memory profiling  
npm run profile:memory

# Request tracing
npm run trace:requests

Next Steps ​

  1. Choose Your Component: Start with CEO or ACS based on your needs
  2. Follow Implementation Guide: Use reference implementations as starting point
  3. Run Tests: Verify your implementation works correctly
  4. Deploy and Monitor: Use production deployment guide
