Vibe Coding Prompts That Actually Work: copy-paste templates for every step
The difference between a vibe-coded app that works and one that falls apart is usually the prompt. Here's a simple formula for writing good ones, plus ready-to-use templates for starting a project, adding features, fixing bugs, polishing the design and checking security.
The best vibe coding prompts tell the AI exactly what to build, who it's for, what it should look like, what to leave alone, and how you'll know it works. Vague prompts like "make me an app" or "fix it" force the AI to guess, and guesses are where broken features, surprise redesigns and endless bug loops come from. Clear, small, checkable prompts get you working software faster.
If you're new here, vibe coding means building software by describing what you want to an AI in plain English and letting it write the code. Andrej Karpathy coined the term in a post on X on February 2, 2025, and our complete guide to what vibe coding is covers the meaning and history. Since your prompts are basically your code now, this guide is about writing them well.
- Use the 5-part formula: goal, context, details, limits, and a "done when" check.
- One change per prompt. Small steps are easier for the AI to get right and easier for you to undo.
- Say what must not change ("only edit the settings page").
- Paste exact error messages instead of describing them.
- Plan before you build anything bigger than one screen: ask the AI to ask you questions first.
- Save working versions before every risky prompt, and ask for a security review before launch.
Why most vibe coding prompts fail
An AI coding tool can't read your mind. When a prompt leaves out details, the model fills the gaps with its own assumptions: a generic layout, features you didn't ask for, a database you didn't need. Anthropic's own best-practices guide for Claude Code puts it simply: "The more precise your instructions, the fewer corrections you'll need." The same advice shows up across the official docs of the most popular vibe coding tools:
- Lovable recommends scoping every change by stating what to build, where it goes and what must stay untouched, and building one component at a time.
- Replit tells Agent users to plan first, break goals into stages, define fields and validation rules, and include the exact error message when debugging.
- Claude Code recommends giving the AI a way to verify its work, such as tests, a build or a screenshot to compare, and separating exploring and planning from coding.
Notice the pattern: none of them say "use magic words." Good prompts aren't about tricks. They're about the same things a good brief to a human developer would include. The four most common prompt mistakes are:
- Too big: "Build me a full social network." The AI produces a fragile shell that breaks the moment you change anything.
- Too vague: "Make it better." Better how? Faster, prettier, simpler?
- No boundaries: you ask for a new button and the AI "helpfully" redesigns your whole page.
- No check: the AI says "done" and you only find out it isn't when a user does.
The anatomy of a prompt that works
You don't need to memorize a complicated framework. Almost every strong vibe coding prompt has the same five parts. You won't need all five every time (a tiny tweak might only need one line), but checking your prompt against this list fixes most problems before they happen.
| Part | What it answers | Example |
|---|---|---|
| 1. Goal | What are we building or changing? | "Add a dark mode toggle to the header." |
| 2. Context | Who is it for? Where in the app? | "This is a recipe app for busy parents. The header is in the top nav component." |
| 3. Details | Exactly what should it do and look like? | "Sun/moon icon, remembers the choice after refresh, smooth fade." |
| 4. Limits | What must not change? What to avoid? | "Don't change any colors on the recipe cards. No new libraries." |
| 5. Done when | How will we check it works? | "Done when the toggle works on mobile and desktop and the choice survives a page reload." |
Here's the formula as a fill-in-the-blanks template you can reuse for almost anything:
// The 5-part vibe coding prompt "Goal: [what to build or change, in one sentence]. Context: [who it's for / which page or file / what already exists]. Details: 1. [behavior or feature] 2. [behavior or feature] 3. [look and feel: colors, layout, mobile] Limits: [what must stay the same / what to avoid]. Done when: [how we'll test that it works]."
The "Done when" line is the one beginners skip most, and it's one of the most valuable. It forces you to think about how you'll test the result, and it tells the AI what success looks like. Claude Code's docs go as far as calling a runnable check "the difference between a session you watch and one you walk away from."
If you couldn't hand your prompt to a freelance developer and get roughly what you want back, it's not clear enough for an AI either.
Weak vs strong: side-by-side examples
Seeing the difference is the fastest way to learn. Each "strong" version below is longer, but it saves you several rounds of back-and-forth.
| Weak prompt | Strong prompt |
|---|---|
| "Make a to-do app." | "Build a to-do app for a student. Add tasks with a due date, tick them off, and sort by due date. Save in the browser. Clean white design, works on a phone. No login." |
| "It's broken, fix it." | "When I click Save, nothing happens and the console shows: [paste error]. Find the cause and fix it. Don't change anything else." |
| "Make it look better." | "Restyle the pricing section only: more spacing between cards, rounded corners, and make the middle card stand out with a violet border. Keep all text the same." |
| "Add payments." | "Before writing code, explain my options for taking one-time payments in this app, what each needs from me, and the security risks. Don't build anything yet." |
| "Make it faster." | "The product list takes several seconds to load with 500 items. Find out why, explain the cause in plain English, then propose a fix before changing code." |
Prompts for starting a new project
Your first prompt sets the direction for everything after it, so it deserves the most care. If you've never built anything before, read our step-by-step guide on how to start vibe coding first, then come back for these templates.
1. The "interview me first" prompt
For anything bigger than a single screen, let the AI ask questions before it writes code. Lovable's docs suggest asking it to query you about a feature before building, and Anthropic recommends having Claude interview you and write a spec for larger features. It catches the decisions you didn't know you had to make.
"I want to build [one-sentence idea] for [who it's for].
Before writing any code, interview me. Ask about the main
features, what users see first, edge cases, and anything
I might not have thought about. Ask a few questions at a
time. When we're done, write a short plan with a feature
list and the order we should build things in."2. The first-build prompt
Once you know what you want, describe version one. Keep it to the smallest thing that's actually useful.
"Build a simple [type of app] for [audience].
Version 1 features only:
1. [core feature]
2. [core feature]
3. [core feature]
Style: [mood, colors, fonts], mobile-friendly.
Save data [in the browser / no saving needed].
Leave out: login, payments, admin pages. We'll add
features later, one at a time."3. The landing page prompt
Landing pages are one of the most popular first projects. Use real copy, not placeholder text; Lovable's guide notes that real headlines and buttons expose layout and wording problems early.
"Create a one-page website for [business/project].
Audience: [who]. Main action: [e.g. book a call].
Sections in order: hero with headline '[your headline]'
and a [button text] button, 3 benefits, how it works
in 3 steps, FAQ, contact form.
Style: [modern/minimal/playful], [color] accents.
Use this exact text where I've given it. Make it fast
and readable on phones."Stuck for an idea to practice on? Spin the Vibe Machine idea generator for a random project, then run it through the templates above.
Prompts for adding features
The golden rule: one feature per prompt, with clear boundaries. Replit recommends building incrementally and saving a checkpoint after each working step; Lovable recommends making one meaningful change at a time and bookmarking working milestones.
4. The scoped feature prompt
"Add [feature] to the [page/screen].
It should: [behavior 1], [behavior 2].
Show a clear message when [empty / loading / error].
Only change the files needed for this feature. Keep the
existing design, text and features exactly as they are.
Done when: [how I'll test it]."5. The "plan it, don't build it" prompt
For risky features (accounts, payments, anything touching a database), ask for options first. This is the same idea as plan mode in tools like Claude Code, Lovable and Replit: think before you change anything.
"I want to add [feature, e.g. user accounts]. Don't write
code yet. Explain 2-3 ways to do it in plain English, what
each needs from me (accounts, keys, cost to check), the
security risks, and which you'd recommend for a beginner
and why. Then list the steps we'd take."6. The "follow the existing pattern" prompt
Once your app has a few screens, ask the AI to copy what already works. Anthropic's docs recommend pointing to existing patterns in your code instead of describing everything from scratch.
"Look at how the [existing feature, e.g. Recipes page]
is built. Create a [new feature, e.g. Shopping List page]
that follows the same structure, styling and naming.
Don't add new libraries."
Prompts for debugging and fixing
Debugging is where most beginners lose hours. The fix is almost always more information, not more frustration. Replit's docs list what to include: the exact error message, the relevant code or file, what you were trying to do, and what you've already tried.
7. The error-message prompt
"I get this error when I [action]:
[paste the exact error message]
What I expected: [expected result].
What I've tried: [anything you tried].
Explain the cause in one or two sentences, then fix the
root cause. Don't hide the error or change unrelated code."8. The "it doesn't error, it's just wrong" prompt
"Bug: when I [steps to reproduce], the app [what happens].
It should [what should happen].
This started after [last change, if you know].
Find the cause before changing anything, tell me what
you found, then make the smallest fix."9. The loop breaker
If the AI has tried to fix the same bug three times and keeps failing, stop. Anthropic's guide notes that after repeated corrections the conversation is "cluttered with failed approaches," and recommends starting fresh with a better prompt. Most tools let you start a new chat or roll back to a saved version.
// Paste into a NEW chat, after restoring your last working version "Context: [one paragraph describing the app]. Problem: [the bug, with exact error]. Already tried and failed: [list the previous attempts]. Suggest a different approach than these. Explain it first, then implement it."
Practice your prompts on something fun
Try Prompt → App in the Vibe Arcade: type a short description and watch a mini app appear. Then play nine free games that were all built from plain-English prompts.
Prompts for design and styling
Design prompts fail when they're vague ("make it pop"). Use specific words: name the element, the change and the feeling. Lovable's guide recommends naming UI elements precisely (cards, badges, form fields, modals) and using verbs like "replace," "update" or "adjust" instead of "make this better."
10. The restyle prompt
"Restyle only the [section/component]:
- Mood: [e.g. calm, premium, playful]
- Colors: [background], [accent], [text]
- Spacing: [more breathing room / tighter]
- Corners and shadows: [e.g. rounded 12px, soft shadow]
Keep all text, links and functionality identical."11. The screenshot prompt
Many tools accept images. A screenshot or sketch beats a paragraph of description, and both Replit and Anthropic recommend sharing mockups or screenshots.
"[attach screenshot or sketch]
Make the [page] match this layout. Use my existing colors
and fonts. When you're done, list any differences between
your version and the image so I can decide what to fix."12. The mobile check prompt
"Check every page at phone width (around 375px). Fix any
text that overflows, buttons that are too small to tap,
or sections that scroll sideways. Don't change the
desktop layout."Prompts for cleaning up and learning
Vibe coding doesn't mean you have to stay in the dark about your own code. Simon Willison made the point in March 2025 that "not all AI-assisted programming is vibe coding": reviewing, testing and understanding the code is what turns a quick experiment into software you can trust. These prompts help you move in that direction at your own pace. For a deeper look at the trade-offs, see vibe coding vs traditional coding.
13. The tidy-up prompt
"Review the code for this project. Remove anything unused,
split very long files into sensible pieces and give things
clear names. The app must behave exactly the same before
and after. List every change you made."14. The explain-it-to-me prompt
"Explain how this app works as if I'm a beginner. Which
file does what? What happens, step by step, when a user
[does the main action]? Keep it short and avoid jargon,
or explain any jargon you use."15. The project-notes prompt
Many tools let you save standing instructions so you don't repeat yourself in every prompt. Claude Code reads a CLAUDE.md file at the start of every conversation, Cursor supports project rules (and a simple AGENTS.md file) that are included at the start of the model's context, and Lovable suggests saving style keywords to your project knowledge. Ask the AI to draft yours:
"Write a short project notes file for this app: what it
does, who it's for, the tech it uses, the design rules
(colors, fonts, tone), and rules you should always follow
(e.g. never change the database without asking). Keep it
under 30 lines. Only include things you couldn't figure
out by reading the code."Keep these notes short. Anthropic's guide warns that bloated instruction files make the AI ignore the rules that matter.
Prompts for security and launch
This is the section most people skip, and the one that matters most if real users will touch your app. In its 2025 GenAI Code Security Report (published July 30, 2025), Veracode tested more than 100 large language models on 80 coding tasks and found AI-generated code introduced security flaws in 45% of cases. AI is fast, not automatically safe. Ask it to check its own work, and get a human review for anything handling money or personal data.
16. The security review prompt
"Act as a security reviewer. Check this app for:
- API keys, passwords or secrets in the code
- pages or data visible without the right login
- forms that trust user input without checking it
- database rules that let users see others' data
List each issue with how serious it is and how to fix it.
Don't change code until I approve the fixes."17. The pre-launch checklist prompt
"I'm about to share this app publicly. Make a checklist
of what to test before launch: every button and form,
empty and error states, mobile, page titles, broken
links, and what happens if someone enters strange input.
Then go through it and tell me what fails."18. The write-tests prompt
"Write simple automated tests for the most important
features: [feature 1], [feature 2]. Include edge cases like
empty input and very long text. Run the tests, fix any
failures in the app (not in the tests), and show me the
results."
Habits that make every prompt better
Templates help, but habits matter more. These come straight from what the tool makers themselves recommend:
- Save before every risky prompt. Use your tool's checkpoints or version history (Replit calls them Checkpoints; Lovable has version history; Claude Code has rewind). If a change goes wrong, roll back instead of arguing with the AI.
- Start a new chat for unrelated tasks. Old conversation history can confuse the AI. Replit's docs say to "start a new chat when switching to unrelated tasks."
- Describe what you want, not only what to avoid. "Use a white background" works better than a long list of things you don't like.
- Use real content. Real text, real product names and real examples produce better layouts than "lorem ipsum."
- Ask for evidence. Ask the AI to show test results or describe exactly what it checked, rather than just saying "done."
- Keep a prompt library. When a prompt works well, save it. Over time you'll build your own set of templates, just like this one.

Frequently asked questions
What is a vibe coding prompt?
A vibe coding prompt is a plain-English instruction you give an AI tool so it writes or changes code for you. Good ones describe the goal, context, details, limits and how you'll check that the result works.
What makes a good vibe coding prompt?
Specific, small and checkable. Say exactly what to build or change, who it's for, what it should look like, what must stay the same, and what "done" means. One change per prompt works far better than a long wish list.
How long should a vibe coding prompt be?
Long enough to remove guesswork. A tiny tweak might be one sentence; a first build or a new feature is often 5 to 15 lines. If the AI keeps guessing wrong, your prompt probably needs more detail, not more words.
Do the same prompts work in Lovable, Bolt, Replit, Cursor and Claude?
Mostly, yes. The principles (be specific, work in small steps, set boundaries, paste exact errors) apply to every tool. Each tool adds its own features, like plan modes, checkpoints, project rules or knowledge files, so check its docs for extras.
How do I stop the AI from changing things I didn't ask for?
Add a limits line to every prompt, such as "only change the settings page" or "keep all existing text and design the same." Save a working version before each change so you can roll back if it goes too far.
What should I do when the AI keeps failing to fix a bug?
Stop after two or three failed attempts. Restore your last working version, open a new chat, describe the app and the exact error, list what already failed, and ask for a different approach explained before any code is written.
Should I ask the AI to plan before it codes?
For anything bigger than a small tweak, yes. Asking the AI to interview you or propose a plan first, often called plan mode, helps you catch missing decisions and avoids building the wrong thing.
Can prompts make AI-generated code secure?
Prompts help, but they aren't a guarantee. Veracode's 2025 research found security flaws in 45% of AI code samples tested. Ask the AI for a security review, test carefully, and get a human review for apps handling payments, logins or personal data.
Where can I practice writing vibe coding prompts?
Start with a tiny personal project and the templates in this guide. You can also try Prompt → App and the Vibe Challenge on our homepage to practice describing what you want in plain English.
