You vibed it,
now ready it.
AI gets you 90% of the way there. The last 10% — permissions, idempotency, error handling, secrets — is where things break. The guide closes the gap between “vibe” and “ready.” Sign up for the free sneak peek and be first in line when the full guide ships.

Looks finished.
Feels finished.
Full of holes.
Hiding the button isn't the same as protecting the endpoint.
AI hides admin buttons from regular users. It rarely checks whether the backend actually blocks those calls.
One refresh, two transactions.
No idempotency guard on a payment endpoint. Every Stripe integration without one is a customer service ticket waiting to happen.
Six database writes. Zero error handlers.
Any one of them failing silently corrupts data. The app shrugs. Nobody knows until a user reports the problem.
Your test Stripe key is live in production.
AI copied it into the frontend during prototyping. Two weeks in production. Visible in the browser network tab.
What one missed check
actually costs you.
100%
A single data leak erases all the goodwill you built. Users don't forgive "AI did it" — they just leave.
3–8 h
Average time to fix a production incident that a 30-minute pre-launch check would have caught.
One shot
Your launch day audience won't come back. First impressions with broken permissions are permanent.
One prompt.
Four findings.
You decide what ships.
It doesn’t compliment your code. It hunts for permission gaps, double-submit windows, missing error handlers and leaked secrets — the stuff AI assumes you’ll never test.
Run it in your existing project. The guide tells you what to look for in the results and which fixes to prioritize.

The frontend is not a security guard
Red flag — do not ship“Hiding a button does not prevent someone from calling the action directly.”
Your interface only shows the delete button to an administrator. But the backend accepts the delete request without checking whether the person making it is actually an administrator.
The full chapter includes the AI prompt to run, what to check in the response, and deeper notes on authorization vs. authentication. Get the sneak peek →
What to fix first.
- 01Protect users and their dataVerify that one user cannot access another user's data and that permissions are enforced on every protected action.Non-negotiable
- 02Prevent irreversible or duplicate actionsEnsure payments, deletions and sensitive operations cannot fire twice and can be recovered when something goes wrong.
- 03Make failures visibleConfirm that errors are logged somewhere you will notice before a user reports the problem to you.When this breaks, the app shrugs and tells nobody
- 04Reduce fragile codeRemove temporary shortcuts, hardcoded values and disabled checks that AI left behind during rapid prototyping.
- 05Improve the polishFix layout quirks, loading states and accessibility issues once the critical risks are under control.Your slightly awkward button can wait

Built for people who build through conversation.
This is for you if:
- —You created most of your application using AI prompts
- —Your project works, but you do not fully trust it
- —Security advice usually feels too technical
- —You are unsure what to inspect before launch
- —AI keeps proposing changes you cannot confidently evaluate
- —You are a junior developer building a repeatable review habit
This is not for you if:
- —You want a professional penetration test
- —You need an advanced infrastructure guide
- —You expect one prompt to certify that an app is secure
- —You are building a regulated or safety-critical product without experienced review
- —You want AI to make every technical decision for you

What the Checkpoint is designed to uncover
Three issues representative of what the Checkpoint catches. Not hypotheticals — patterns observed in AI-built applications.
Hidden admin endpoints
A non-technical founder discovered their "admin only" delete button had no backend permission check. Any logged-in user could delete any record by calling the endpoint directly.
Hardcoded test API keys
A startup founder found their AI had hardcoded a test Stripe key in the frontend. It was visible in the browser network tab and had been live for two weeks.
Silent database failures
A junior developer discovered six database write operations with no error handling. Any one of them failing would have silently corrupted data with no alert.
