V3 DDD Architecture

V3 DDD Architecture

What This Skill Does

Designs and implements Domain-Driven Design (DDD) architecture for Codex-flow v3, decomposing god objects into bounded contexts, implementing clean architecture patterns, and enabling modular, testable code structure.

Quick Start

# Initialize DDD architecture analysis
Task("Architecture analysis", "Analyze current architecture and design DDD boundaries", "core-architect")

# Domain modeling (parallel)
Task("Domain decomposition", "Break down orchestrator god object into domains", "core-architect")
Task("Context mapping", "Map bounded contexts and relationships", "core-architect")
Task("Interface design", "Design clean domain interfaces", "core-architect")

Domain Boundaries

1. Task Management Domain

// core/domains/task-management/
interface TaskManagementDomain {
  // Entities
  Task: TaskEntity;
  TaskQueue: TaskQueueEntity;

  // Value Objects
  TaskId: TaskIdVO;
  TaskStatus: TaskStatusVO;
  Priority: PriorityVO;

  // Services
  TaskScheduler: TaskSchedulingService;
  TaskValidator: TaskValidationService;

  // Repository
  TaskRepository: ITaskRepository;
}

2. Session Management Domain

// core/domains/session-management/
interface SessionManagementDomain {
  // Entities
  Session: SessionEntity;
  SessionState: SessionStateEntity;

  // Value Objects
  SessionId: SessionIdVO;
  SessionStatus: SessionStatusVO;

  // Services
  SessionLifecycle: SessionLifecycleService;
  SessionPersistence: SessionPersistenceService;

  // Repository
  SessionRepository: ISessionRepository;
}
