When should I use this instead of microservices?

Use it when you need strong module isolation but want to avoid the operational complexity of distributed networking, container orchestration, and complex deployment pipelines.

What is a modular monolith?

A modular monolith is an architectural style that maintains a single deployable unit while enforcing strict logical separation between internal modules to improve maintainability.

How does this skill help with team autonomy?

It helps define clear public contracts and boundaries between modules, allowing different teams to work on specific business domains without causing regressions in others.

Can this skill detect architectural violations?

Yes, it provides tools and patterns for dependency analysis that can be integrated into CI/CD to fail builds if forbidden references are introduced between modules.

Developer Tools

Enforces strong internal boundaries and module encapsulation within a single deployable artifact to ensure system scalability and team autonomy.

About

The Modular Monolith Architecture skill provides a structured framework for building systems that combine the operational simplicity of a monolith with the organizational benefits of microservices. By leveraging Domain-Driven Design principles, this skill helps developers define clear module boundaries, encapsulate internal logic using strict public contracts, and implement automated architectural fitness tests. It is particularly effective for teams that need to increase release velocity and reduce code coupling without the immediate overhead of managing distributed infrastructure.
