What is 'Core Obesity Syndrome' in backend development?

It refers to the excessive growth of a shared kernel where business logic from different contexts becomes tightly coupled. This skill prevents it by enforcing minimal shared folders.

How does this skill handle code duplication?

It follows the 'Duplication Over Coupling' principle, preferring to have similar code in separate contexts rather than creating a shared dependency that limits independent evolution.

Can I use this for existing projects?

Absolutely. You can use it to help decide where new files should go or to refactor existing messy structures into clean, vertical slices.

Does this skill work with Domain-Driven Design (DDD)?

Yes, it specifically provides patterns for DDD concepts including Entities, Value Objects, Repositories, and Domain Events within isolated contexts.

Why does it recommend UUIDv7 for entity identifiers?

UUIDv7 is used because it is time-ordered and monotonic, which provides significantly better database index performance compared to random UUIDs while remaining unique.

Enforces Clean Architecture principles for Modular Monoliths to ensure domain isolation and prevent architectural decay.

This skill guides Claude in structuring backend applications using isolated bounded contexts and a minimal shared kernel to prevent 'Core Obesity Syndrome.' It provides strict patterns for organizing code into Domain, Application, and Infrastructure layers, prioritizing 'Duplication Over Coupling' to maintain clear boundaries. It is essential for developers building scalable Node.js or TypeScript backends who want to implement Domain-Driven Design (DDD) with high maintainability and low technical debt.
