Refactoring shallow modules improves codebase testability by consolidating scattered logic into deep, cohesive components. The skill analyzes dependency graphs and call flows to propose structural improvements that enhance locality and leverage, making interfaces simpler and logic centralized.

A shallow module in software architecture is a component with an overly complex interface and scattered internal logic. This creates architectural friction that makes the codebase difficult to test and navigate, requiring structural improvements to create deep, cohesive units with better locality.

You can visualize dependency graphs and call flows by generating self-contained HTML reports with Mermaid diagrams and custom SVG visuals. These visual reports illustrate dependency flows and deepening opportunities to facilitate collaborative design decisions and architectural alignment.

No specific dependencies or environment setup are required to run this architectural analysis. You can invoke the skill directly to scan the current repository and generate an architectural review report in the system temporary directory without external components.

The best way to enforce consistent design vocabulary during codebase refactoring is to apply a strict domain and architectural vocabulary. This ensures consistent communication and decision-making when identifying shallow modules and proposing structural improvements for deepening components.

You should avoid automated architectural refactoring proposals when your codebase lacks clear dependency graphs or call flows to analyze. Without traceable structural data, generating accurate visual HTML reports or proposing cohesive deep modules becomes unreliable for collaborative design decisions.
