How does this skill improve code maintainability?

It reduces coupling between modules. By ensuring modules only talk to 'immediate friends' and delegate logic to data owners, it prevents a change in one area of the code from causing a cascade of failures elsewhere.

What is the 'Tell, Don't Ask' principle mentioned in this skill?

It's a design pattern where you tell an object or module to perform an action using its own data, rather than asking for its data to perform the logic yourself, which keeps business rules encapsulated.

Can I use this skill to refactor existing legacy code?

Yes, the skill is excellent at identifying 'code smells' like deep property chaining or fragile inheritance trees and suggesting structural improvements based on industry best practices.

Does this skill only work for Object-Oriented Programming?

No, while these principles originated in OOP, this skill provides specific translations for functional programming paradigms, such as using function composition and module boundaries in Elixir.

开发者工具

Implements robust, maintainable software architectures using Composition, Law of Demeter, and Tell Don't Ask principles across all programming paradigms.

关于

The Structural Design Principles skill empowers Claude to architect modules and components that are resilient to change and easy to test. By applying core concepts like Composition Over Inheritance and the Law of Demeter, this skill helps developers reduce code coupling and maintain clear boundaries between data and logic. Whether you are building functional systems in Elixir or object-oriented applications in TypeScript/React, this skill provides the necessary patterns to ensure business logic lives with the data it owns, preventing the 'train wreck' code smells and fragile hierarchies that plague complex codebases.
