Multi-Service Orchestration

Overview

Multi-service management methodology adapted from the Everything Claude Code project. Handles service discovery, dependency resolution, PM2 management, cascade/parallel execution, and cross-service testing.

Service Discovery

• Scan for service directories (packages/, services/, apps/)
• Parse package.json for dependencies and scripts
• Build dependency graph
• Detect package managers per service
• Determine topological execution order
• Flag circular dependencies

Execution Modes

Cascade Mode

• Sequential execution following dependency order
• Wait for health check before starting dependents
• Stop on failure with detailed error report
• Support partial cascade (skip healthy services)

Parallel Mode

• Concurrent execution for independent services
• Optional worktree isolation per service
• Configurable concurrency limit
• Collect all results (continue on individual failures)

Auto Mode (Default)

• Analyze dependency graph
• Use cascade for services with sequential dependencies
• Use parallel for independent service groups
• Hybrid: cascade between groups, parallel within groups

PM2 Management

• Generate ecosystem.config.js from service manifest
• Configure per service: name, script, cwd, env, instances
• Start in topological order with health check gates
• Log rotation and restart policies
• Status monitoring: online, stopped, errored

Cross-Service Testing

• API contract verification (request/response schemas)
• Event bus message flow testing
• Shared state consistency checks
• Authentication across service boundaries
• Circuit breaker behavior validation

Health Monitoring

• Health check endpoint polling
• PM2 process status monitoring
• Resource usage tracking (CPU, memory)
• Log file error pattern detection
• Inter-service connectivity verification

When to Use

• Multi-package monorepo development
• Microservice orchestration
• Full-stack application management
• CI/CD pipeline for multi-service deployments

Agents Used

• architect (service discovery and dependency mapping)
• build-resolver (individual service builds)
• e2e-runner (cross-service integration testing)
