What is the 'Library-First' approach in this skill?

The Library-First approach is a philosophy that encourages searching for existing, well-maintained libraries (npm, PyPI, etc.) or SaaS solutions before writing custom code to minimize future maintenance costs.

Which architectural patterns does the Developer skill implement?

The skill focuses on implementing the Repository pattern for data access, the Service pattern for business logic, and the Factory pattern for complex object creation.

Does this skill help with code quality and testing?

Yes, it promotes a TDD (Test-Driven Development) workflow and includes checklists for refactoring and ensuring adherence to core implementation principles.

How does this skill handle technical debt?

It actively identifies and avoids anti-patterns like 'Not Invented Here' (NIH), premature optimization, and over-engineering to keep the codebase lean and maintainable.

About

This skill transforms Claude into a high-performance feature implementation specialist focused on writing clean, maintainable code while minimizing technical debt. It enforces a 'Library-First' philosophy, guiding the developer to leverage existing open-source solutions (npm, PyPI, Maven) before writing custom logic. By applying standard patterns like Repository, Service, and Factory, it ensures that every feature is built with scalability, testability, and clear separation of concerns in mind, making it ideal for professional software engineering tasks.

Library-First evaluation to prioritize existing solutions over custom code
Standardized implementation of Repository, Service, and Factory patterns
Test-Driven Development (TDD) workflow integration
Clear separation of domain logic from infrastructure and data access
Anti-pattern detection for NIH (Not Invented Here) and over-engineering
0 GitHub stars

Use Cases

Building complex backend business logic for new application features
Refactoring monolithic codebases into structured architectural patterns
Selecting and integrating the most efficient third-party libraries for common tasks
