File contents

Refactor Assistant

Code review yourself before anyone else does. Point this at a file and get specific refactoring suggestions with diffs.

One command. Zero config. Just works.

Quick Start

npx ai-refactor src/utils.ts

What It Does

Analyzes code for improvement opportunities
Shows colored diffs for suggested changes
Focuses on readability and patterns
Can apply changes automatically

Usage Examples

# See suggestions
npx ai-refactor src/utils.ts

# Apply changes directly
npx ai-refactor src/utils.ts --apply

# Focus on specific area
npx ai-refactor src/api.ts --focus "error handling"

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
