SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires inversify.

What problem does it solve? Building a modular TypeScript codebase without clear architectural boundaries leads to tangled dependencies, untestable business logic, and fragile domain models. This Skill provides a complete blueprint for implementing claude-flow v3 core modules using Domain-Driven Design, clean architecture, and dependency injection. ## Core Features & Use Cases - DDD Domain Modeling: Provides base classes for Entities, Value Objects, and Aggregate Roots, plus a full Task Management domain with entities, value objects, domain events, and services. - Clean Architecture Layers: Defines repository interfaces with SQLite implementations, application-layer use cases (e.g., AssignTaskUseCase), and an Inversify-based dependency injection container. - Testing & Quality: Includes unit tests for domain entities, integration tests for repositories, strict TypeScript configuration, and entity caching for performance. - Use Case: When scaffolding the claude-flow v3 core, use this Skill to generate the task-management, session-management, and health-monitoring domains with consistent patterns and >90% test coverage targets. ## Quick Start Ask the AI to implement the claude-flow v3 core domains with DDD patterns, clean architecture, and comprehensive tests using this Skill.

Frequently Asked Questions about V3 Core Implementation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement DDD entities and value objects in TypeScript?▼

Create abstract base classes: an Entity with identity equality and domain event tracking, and a ValueObject with frozen props and structural equality. Extend AggregateRoot for event sourcing with version increments on each applied event.

How to structure a clean architecture TypeScript project?▼

Organize code into domains (entities, value objects, services, repositories, events), a shared kernel (base classes, event bus, DI container), and an application layer (use cases, commands, queries, handlers). Dependencies point inward toward the domain.

What dependency injection library works with TypeScript decorators?▼

Inversify works with TypeScript decorators like @Injectable and @Inject when experimentalDecorators and emitDecoratorMetadata are enabled in tsconfig. Bind interfaces to implementations in a container using singleton scope for repositories and services.

How do I test domain entities without a database?▼

Write unit tests against entity behavior directly: create entities via factory methods, invoke domain methods like assignTo, and assert state changes and emitted domain events. Use in-memory SQLite only for repository integration tests.

When should I use domain events in DDD?▼

Use domain events when state changes need to trigger side effects across aggregates, such as publishing TaskAssignedEvent after assignment. Collect uncommitted events on the aggregate, publish them after persistence, then mark them committed.
