Ruby Code Review & Refactoring Guide

Analyze Ruby code for unnecessary custom objects, class bloat, and insufficient usage of Ruby's generic data structures. Provide specific refactoring steps with before/after code examples for libraries, gems, CLI tools, and Ruby applications.

Scope Determination

Determine scope from the user's request:

• File paths (e.g., lib/parser.rb): analyze only those files
• Directory paths (e.g., lib/services/): analyze all Ruby files in that directory
• Branch name: compare current branch against it to review only changed files
• No scope specified: perform full codebase audit of lib/ directory
• Focus area (e.g., "command objects", "data structures"): prioritize that aspect

Required Skill

MANDATORY: Load the simplifying-ruby-code skill and apply its principles throughout the analysis. Reference specific patterns explicitly (e.g., "Pattern 1: Command Objects -> Module Functions").
