Code Refactoring Skills Pack for Claude Code

The Code Refactoring Skills Pack is the most comprehensive refactoring toolkit for Claude Code, featuring five specialized skills, two slash commands, and a unique 3-agent parallel code review system. Transform messy codebases into clean, maintainable architectures with confidence that nothing breaks in the process.

What You Get

• Extract and Modularize Skill — Identifies code that should be extracted into separate functions, modules, or services, then performs the extraction with all references updated
• Design Pattern Skill — Recognizes opportunities to apply design patterns (Strategy, Observer, Factory, etc.) and implements them with proper abstractions
• Dead Code Elimination Skill — Finds and safely removes unused imports, unreachable code, deprecated functions, and orphaned files across your entire project
• Type Safety Skill — Strengthens TypeScript types, removes any-casts, adds proper generics, and ensures end-to-end type safety from API to UI
• Performance Refactoring Skill — Optimizes algorithms, reduces unnecessary re-renders, improves database query patterns, and eliminates memory leaks
• /refactor Command — Launches a comprehensive refactoring session with the 3-agent parallel review: one agent refactors, one reviews for correctness, one checks for regressions
• /simplify Command — Reduces complexity of any function or module while preserving behavior, guided by cyclomatic complexity metrics

How to Install

Extract into your .claude/ directory. Use /refactor with a file or directory path to start a guided refactoring session. The 3-agent parallel review ensures every change is validated before being applied. Use /simplify on complex functions for targeted complexity reduction.

Who This Is For

• Developers working with legacy codebases that need modernization
• Tech leads paying down technical debt systematically
• Teams preparing codebases for scale or new feature development
• Anyone who wants to refactor with confidence that tests still pass
