Professional Code Refactoring

About

The Professional Code Refactoring skill provides a disciplined, safety-first framework for improving codebases within Claude Code. By enforcing a test-driven workflow, it guides the model to identify code smells, plan incremental changes, and verify behavior after every modification. This skill is essential for developers looking to reduce technical debt, eliminate duplication, and break down complex logic into clean, modular components without the risk of introducing regressions.

Key Features

• Automated identification of code smells and high-complexity areas
• Integration with simplicity principles like KISS, YAGNI, and the Boy Scout Rule
• Test-driven safety protocol requiring verified tests before and after changes
• Pre-defined patterns for function extraction and conditional simplification
• Incremental 'one-change-at-a-time' workflow for manageable commits
• 72 GitHub stars

Use Cases

• Breaking down 'God classes' or oversized functions into modular, reusable units
• Simplifying deeply nested conditional logic to improve code path clarity
• Consolidating duplicated logic across multiple modules to centralize maintenance
