What problem does it solve?

Microservices introduce operational complexity, but traditional monoliths can become "big balls of mud." This skill guides you in building a modular monolith, offering microservice-like team autonomy with a single deployable artifact.

Core Features & Use Cases

• Module Identification: Align boundaries with business capabilities or bounded contexts.
• Internal Encapsulation: Use language features (visibility, namespaces) to hide implementation details.
• Contract Exposure: Define clear facades, APIs, or events for inter-module communication.
• Architecture Enforcement: Implement automated tests to prevent forbidden imports or package references.
• Use Case: Refactor a monolithic application into a modular monolith by identifying distinct business capabilities (e.g., Order Management, Inventory), encapsulating their internals, and enforcing boundaries with architecture tests.

Quick Start

Identify clear module boundaries within your application, then encapsulate their internals using language-specific features like namespaces.
