modularity

What problem does it solve?

This skill helps teams enforce small, focused modules to prevent changes from ballooning in scope, reduce coupling, and maintain context when refactoring, splitting, or modularizing codebases.

Core Features & Use Cases

• Rule-based guidance for size, responsibility, change locality, interface design, and dependency direction to ensure modular boundaries.
• Use Case: during planning and review, when planning large changes (split/decouple/refactor), apply Modularity Checklist, and ensure changes touch at most a few files and are organized by feature/domain.

Quick Start

Decompose a large change into focused modules by identifying feature boundaries and creating clear interfaces before implementation.
