How does it detect code duplication?

The skill uses Grep, Glob, and specialized scripts to find similar logic blocks, repeated function signatures, and structural similarities across different files.

How does it analyze system architecture?

It maps directory structures, identifies layer boundaries (like data vs. presentation), and searches for indicators of specific architectural patterns like the Repository or Service Layer patterns.

What software patterns can this skill identify?

It recognizes Gang of Four patterns (Factory, Singleton, Observer, etc.), architectural styles (MVC, MVVM, Microservices), and code-level patterns like naming conventions and error handling strategies.

Can this skill help with refactoring?

Yes, it specifically identifies anti-patterns and redundant code, providing recommendations on where to extract shared utilities or apply better design patterns.

Does it support different programming languages?

While it is highly effective in TypeScript and JavaScript environments, its pattern discovery methodology is designed to work across most object-oriented and functional codebases.

開発者ツール

Analyzes codebases to identify design patterns, architectural structures, and recurring code conventions for better system understanding.

The Pattern & Architecture Analyzer skill empowers Claude to perform deep structural analysis of complex software projects. By leveraging specialized search strategies and systematic methodologies, it detects Gang of Four design patterns, system architectures like MVC or Hexagonal, and identifies problematic anti-patterns. Whether you are onboarding to a legacy codebase or conducting a formal architectural review, this skill provides the insights needed to document naming conventions, find code duplication, and uncover refactoring opportunities to improve long-term maintainability.
