Refactor Assist

Best Practices

• Review before applying - verify suggestions make sense
• Commit first - have a clean state to diff against
• Focus on one thing - don't refactor everything at once
• Run tests after - make sure nothing broke

When to Use This

• Code review prep
• Cleaning up old code
• Learning better patterns
• Technical debt sprints
