name: refactor-assist description: Get refactoring suggestions with colored diffs. Use when improving code quality.

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

How It Works

Reads your file, sends it to GPT-4o-mini for analysis, and shows refactoring suggestions as diffs. Looks at readability, duplication, modern patterns, performance, and type safety.
