SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill addresses the common issue of shallow, tightly coupled codebases that are difficult to test and maintain by providing a shared vocabulary and architectural framework for building deep modules.

Core Features & Use Cases

  • Architectural Vocabulary: Standardizes terms like module, interface, seam, and adapter to ensure consistent communication across the development team.
  • Deepening Strategies: Provides actionable guidance on how to refactor shallow modules into deep ones, improving leverage and locality.
  • Design-It-Twice Pattern: Facilitates parallel exploration of interface designs to ensure the most robust and flexible solution is chosen.

Quick Start

Use the codebase-design skill to analyze the current module structure and suggest a deepening strategy for the identified dependencies.

FAQPage Schema
What is a deep module in software design and how does it improve testability?▼

Deep modules provide a simple interface hiding complex implementation, improving testability by isolating dependencies and reducing tight coupling across the codebase architecture.

How do I refactor shallow modules into deep modules for better maintainability?▼

Refactor shallow modules by applying deepening strategies that clean module seams and minimize interfaces, improving architectural leverage and locality across complex codebase dependencies.

When should I use the design-it-twice pattern for interface design?▼

Use the design-it-twice pattern during interface design to explore parallel architectural solutions, ensuring selection of the most robust and flexible module boundary before implementation.

Does this architectural framework work for complex codebase refactoring?▼

Yes, this architectural framework applies to software refactoring, interface design, and testability improvement within complex codebases by standardizing module boundaries and adapter implementation.

How do I standardize architectural vocabulary like seams and adapters across a development team?▼

Standardize architectural vocabulary by adhering to a defined glossary of terms like module, interface, seam, and adapter, ensuring consistent module boundary communication across development teams.

What are the limitations of using deep modules for software architecture?▼

Deep module design requires strict adherence to defined design principles and glossaries; if existing codebases lack clear seams, adapter implementation and boundary refactoring demand significant upfront structural analysis.
