Description
Architecture and type design principles. Use when designing or reviewing an architecture, refactoring a module or class, or reviewing the design of a type.

Design Principles

Scope: Architecture design patterns applying SOLID (defined in @smith-principles/SKILL.md) Prerequisites: @smith-principles/SKILL.md (SOLID, DRY, KISS, YAGNI, MECE)

Before You Finish

When designing or reviewing architecture:

  1. Apply Single Responsibility - each module has one reason to change
  2. Design for extension without modification (Open/Closed)
  3. Ensure subtypes are substitutable (Liskov)
  4. Prefer small, focused interfaces (Interface Segregation)
  5. Depend on abstractions, not implementations (Dependency Inversion)

Claude Code Plugin Integration

When pr-review-toolkit is available:

  • type-design-analyzer agent: Rates type design on 4 dimensions (1-10 each)
    • Encapsulation
    • Invariant expression
    • Usefulness
    • Enforcement
  • Trigger: "Review the «TypeName» type design" or use Task tool
