Vibe Refactoring: 20+ Prompts to Clean Up AI Code

Half of vibe coding is cleanup. I learned this the hard way. Here are 20+ refactoring prompts that turn spaghetti into code you'll actually maintain.

Here's a truth nobody wants to hear: vibe refactoring should be 50% of your vibe coding work.

Not 10%. Not "whenever you feel like it." Half.

I know, I know. You didn't sign up for this. You came for the magic—describe what you want, watch code materialize, ship it. And that part? Genuinely amazing. But Cursor's CEO Michael Truell dropped a warning in December 2025 that should terrify anyone building real projects with AI: vibe-coded foundations are "shaky" and will "crumble" as your project grows.

He's right. I've watched it happen. Built something beautiful in an afternoon, then spent a week untangling the mess once it grew beyond three components.

The good news? There's a fix. And it's not "be more careful" or "plan better." It's having the right vibe refactoring prompts in your toolkit.

Key Takeaways:

Vibe refactoring should be 50% of your workflow—not an afterthought

5 Signs Your AI Code Is Rotting

Before we get to the prompts, let's talk diagnosis. Here's when to stop building and start cleaning:

1. You're afraid to touch certain files. You know the ones. That 400-line component where everything somehow works and you have no idea why. If you're navigating around code like it's a minefield, that's technical debt screaming at you.

2. "It works" is your best explanation. When someone asks how a feature works and your answer is basically a shrug? Bad sign. AI generates working code, but it doesn't generate understanding. That gap will bite you.

3. Copy-paste is your testing strategy. Found yourself copying a component and tweaking it instead of extending the original? That's duplication creeping in. And it compounds fast.

4. You can't find anything. If searching your codebase feels like archaeological excavation, your file structure needs help. AI doesn't naturally organize—it just puts things... somewhere.

5. Every change breaks something unrelated. This is the death spiral. Tightly coupled code where components depend on each other in mysterious ways. Classic AI code smell.

Any of these sound familiar? Don't panic. These vibe coding mistakes are recoverable with the right approach.

The 5 AI Code Smells Nobody Talks About

Let me be blunt: AI-generated code has specific patterns that cause problems. Not because the AI is bad—it's optimizing for "working code that answers your prompt." Not "maintainable code for a growing project."

Code Smell	What It Looks Like	Why AI Does This
Monolithic Components	300+ line files doing everything	AI answers the whole prompt at once
Inline Everything	Styles, logic, constants all mixed	Fewer files = simpler response
Prop Drilling Hell	Props passed through 4+ layers	No natural state management awareness
Magic Numbers	`setTimeout(() => {}, 1500)`	Works without explanation
Duplicate Logic	Same validation in 5 places	Each prompt answered in isolation

The frustrating part? Each piece of AI-generated code works perfectly in isolation. It's when you combine them that things get messy.

Component Cleanup Prompts (React/Tailwind)

Alright, here's where we fix things. These vibe refactoring prompts target the most common component issues.

5 Signs Your AI Code Is Rotting

Split Monolithic Components

Your 400-line monster needs to become manageable pieces. Try this:

Analyze this component and suggest how to split it into smaller,
focused components. Identify:
- UI elements that could be extracted (cards, lists, headers)
- Logic that could become custom hooks
- Any repeated patterns

Don't rewrite yet - just give me a refactoring plan with file names.

[paste your component]

This two-step approach matters. You want a plan before AI starts rewriting. Otherwise you'll get one messy file turned into three messy files.

Extract Business Logic

Extract the business logic from this component into a custom hook.
The hook should:
- Handle all state management
- Expose only what the component needs
- Have a clear, typed return value

Keep the component focused only on rendering.

[paste your component]

Clean Up Inline Styles

Refactor this component to use Tailwind CSS properly:
- Replace any inline styles with Tailwind classes
- Extract repeated class combinations into @apply directives or constants
- Group related utility classes logically
- Add responsive breakpoints where it makes sense

Current component:
[paste your component]

File Structure Organization Prompts

AI will dump everything in whatever folder seems vaguely correct. Here's how to fix it.

Audit and Reorganize

Review this React project structure and suggest a better organization:

Current structure:
[paste your folder tree]

I want:
- Components grouped by feature, not type
- Clear separation of hooks, utils, and types
- A structure that scales to 50+ components

Give me the proposed new structure and a migration plan.

Create Index Files

Once your structure is clean, index files make imports manageable:

Create index.ts barrel files for these directories:
- components/
- hooks/
- utils/

Each index should export all public items from that directory.
Use named exports, not default exports.

This turns

import { Button } from '../components/Button/Button'

into

import { Button } from '@/components'

. Small thing, huge quality-of-life improvement.

DRY Prompts - Kill the Duplicates

This is the hill I'll die on: duplicate code is the #1 killer of vibe-coded projects.

You build a card component. Then another page needs a similar card. AI generates a new one. Now you have two cards. Then three. Then you need to change the border radius on all of them and suddenly you're in hell.

Find Duplicates

Analyze these components and identify:
1. Identical or near-identical code blocks
2. Similar patterns that could be abstracted
3. Shared logic that should be in utilities

For each finding, suggest the extraction strategy.

Components:
[paste multiple components]

Create Shared Components

Create a reusable [ComponentName] component that handles all these variations:
[describe the variations you've found]

Requirements:
- Use props to control variations (not separate components)
- Include TypeScript types for all props
- Add sensible defaults
- Include size/variant props if applicable

Utility Extraction

Extract shared logic from these components into utility functions:
[paste code with duplicate logic]

Create:
- Pure utility functions in utils/
- Custom hooks for stateful logic in hooks/
- Type definitions in types/

Each utility should have a single, clear responsibility.

If you haven't read about context engineering, do it. It's the key to getting AI to understand your existing patterns instead of creating new duplicates.

Readability & Naming Prompts

Naming is famously the hardest problem in programming. AI is... not great at it. You'll get

handleClick

data

, and

temp

a lot.

Improve Variable Names

Improve the variable and function names in this code to be more descriptive:
[paste code]

Rules:
- Names should explain what/why, not how
- Use domain terminology where appropriate
- Boolean variables should read as questions (isLoading, hasError)
- Event handlers should be onVerbNoun (onSubmitForm)

Add Comments Where Needed

Add comments to this code only where genuinely helpful:
[paste code]

Comment rules:
- Explain WHY, never WHAT
- Document non-obvious business logic
- Skip obvious code (no "increment counter" comments)
- Add JSDoc for exported functions

Honestly? Most vibe-coded projects need fewer comments and better names. If you need a comment to explain what code does, rename the code.

TypeScript Enhancement Prompts

If you're vibe coding with TypeScript (and you should be), AI often creates loose types or skips them entirely. Here's how to tighten things up.

Add Proper Types

Add comprehensive TypeScript types to this code:
[paste code]

Requirements:
- No 'any' types (use 'unknown' if truly needed)
- Extract shared types to a types.ts file
- Use interfaces for object shapes, types for unions
- Add JSDoc descriptions to exported types

Create Type Guards

Create type guard functions for these types:
[paste your types]

Each guard should:
- Return proper TypeScript type predicates
- Handle edge cases (null, undefined)
- Be usable in conditional logic

Fix API Response Types

Create proper types for this API response:
[paste sample JSON response]

Include:
- Main response interface
- Nested object types
- Nullable fields marked correctly
- Optional fields where appropriate

The Refactoring Workflow That Actually Works

Prompts are tools. But tools without a system are just chaos. Here's the workflow:

Build → Review → Refactor → Test → Repeat

That's it. Four steps in a loop.

Step 1: Build (but Stop Sooner)

Build features in smaller chunks. Instead of "build me a complete dashboard," try "build me the sidebar navigation" then stop. Review. Then continue.

Step 2: Review (Actually Look at the Code)

After each generation session, spend 5 minutes reading what AI produced. Not debugging—reading. Look for:

Obvious duplication
Files that are too long
Names that don't make sense

Step 3: Refactor (Use These Prompts)

Pick the most pressing issue and use the appropriate prompt from above. One refactor at a time. Don't try to fix everything at once.

Step 4: Test (Manually or Automated)

Verify the refactored code works. Click through the UI. If you've got tests, run them. This catches when refactoring breaks something.

The Refactoring Schedule

Here's my controversial opinion: schedule your refactoring.

Frequency	What to Do
Every session	5-min code review before stopping
Weekly	Run through DRY prompts on new code
Monthly	File structure audit and reorganization
Before launch	Full TypeScript + naming pass

Sounds excessive? Maybe. But you know what's more excessive? Rewriting your project from scratch because it became unmaintainable. I've seen it happen. Multiple times.

The projects that survive long-term follow vibe coding best practices from day one. Refactoring is a practice, not an event.

Frequently Asked Questions

What is vibe refactoring?

Vibe refactoring is the practice of cleaning up, reorganizing, and improving AI-generated code. It addresses the unique problems that come from vibe coding—like duplicate logic, monolithic components, and poor file organization. Think of it as maintenance for your AI-built projects.

How often should I refactor vibe code?

Quick reviews should happen every coding session (5 minutes minimum). Deeper refactoring for duplication and structure should happen weekly if you're actively building. Before any significant release, do a comprehensive pass on types and naming.

What's the biggest vibe coding mistake that needs refactoring?

Duplicate code, hands down. AI generates fresh code for each prompt, so similar components often contain nearly-identical logic. This becomes maintenance nightmare fast. Use the DRY prompts above to find and eliminate duplicates early.

Can I prevent the need for refactoring?

Partially. Better prompts and context engineering reduce cleanup needs. But you can't eliminate refactoring entirely—it's built into how AI coding works. The goal is controlled, scheduled maintenance rather than emergency cleanups.

Is refactoring worth it for small projects?

For throwaway prototypes, skip it. For anything you'll maintain beyond a week? Absolutely. Small projects grow. What starts as "just a quick tool" becomes the thing you're still using months later. Future you will thank present you.
