What problem does it solve?

Rails projects often struggle to map domain concepts to Rails structures without fighting Rails conventions or over-engineering. This skill provides a Rails-first approach to modeling entities, value objects, aggregates, domain services, and domain events in a way that respects Rails defaults while preserving clear domain boundaries.

Core Features & Use Cases

• Rails-first mapping guidance: align domain concepts with appropriate Rails homes (models, services, policies) to keep code expressive and maintainable.
• Invariant-driven design: prioritize domain invariants and ownership, guiding when to introduce boundary objects like services or repositories.
• Integration planning: outlines a pragmatic sequence from domain concepts to implementation, tests, and documentation.

Quick Start

Identify the domain concepts and map them to Rails structures following the Rails-first guidance provided herein.
