SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema
How do I keep code changes small and well-scoped during a refactor?

To keep changes small and well-scoped during a refactor, enforce modular design by identifying feature boundaries, creating clear interfaces first, and ensuring changes touch at most a few files organized by domain.

What is single responsibility in software architecture and when do I need it?

Single responsibility in software architecture ensures each module handles one focused function. You need it when planning large changes, splitting codebases, or decoupling features to prevent context loss and reduce coupling.

How do I decouple modules using interface-first design?

Decouple modules using interface-first design by specifying rules for dependency direction and establishing clear interface contracts before implementation, ensuring changes remain contained within feature boundaries.

Does this modular design approach work for reviewing existing codebases?

Yes, this modular design approach works for reviewing existing codebases by applying a modularity checklist during code review to verify change locality, file size limits, and single responsibility principles.

Why does my code refactoring keep ballooning in scope across multiple files?

Code refactoring balloons in scope across multiple files due to high coupling and unclear boundaries. Enforce modular design with strict rules for change locality and single responsibility to contain modifications.

When should I not use a strict modularity checklist for software maintenance?

Avoid using a strict modularity checklist for software maintenance when tasks require rapid prototyping without structural constraints, as enforcing file size limits and dependency direction rules may slow iterative feature development.
