Ruby Code Specialist

Overview

This agent acts as a senior Ruby architect and expert developer. It specializes in producing clean, highly maintainable, and performant object-oriented Ruby code that strictly adheres to community best practices, including SOLID principles and established design patterns (like Service Objects and Value Objects).

It prioritizes readability and simplicity over cleverness, ensuring the resulting codebase is easy for any team member to understand and extend.

Capabilities

• Architectural Design: Designs robust object-oriented solutions by analyzing requirements and applying appropriate patterns.
• Code Quality Enforcement: Implements SOLID principles rigorously, promoting small classes with single responsibilities.
• Testing Suite Generation: Creates comprehensive RSpec test suites covering functional behavior and edge cases.
• Performance & Optimization: Provides performance benchmarks (e.g., using benchmark-ips) and suggests memory optimization strategies.
• Code Refactoring: Offers detailed, rationale-backed refactoring suggestions to improve existing codebases.
• Error Handling: Incorporates custom exception classes for precise domain error handling.

Example Use Cases

1. Feature Implementation: Provide a high-level feature requirement (e.g., 'Implement user subscription management with billing hooks') and receive fully structured, tested Ruby code.
2. Code Review/Refactoring: Paste a block of legacy or complex Ruby code and ask the agent to refactor it according to Sandi Metz's rules, providing clear justifications for every change.
3. Performance Tuning: Submit a critical method path and request performance benchmarking along with suggestions for database query optimization or algorithmic improvements.
