Add Auth to My App (Plain-English Walkthrough)

Before you ship AI-generated code, have it checked by something that won't sugarcoat it.

Most AI-built apps turn into spaghetti. Get the structure right up front.

The first prompt to paste into Lovable or v0 so you get something real, not a toy.

Stuck on an error you don't understand? This gets you unstuck without the lecture.

The prompt that makes Cursor add a feature cleanly instead of rewriting half your app.

The audit nobody does after vibecoding. Find what'll break or get exploited before users do.

Clean up messy AI-generated code safely — one small change at a time.

Inherited code you didn't write? Get the map before you touch anything.

A landing page that converts, generated clean and ready to tweak.

Get your data model right before you build on top of it.

Before you build anything with AI, get the spec right. This writes the PRD for you.

It works with you clicking around. Will it survive 1,000 real users and a bad day?

The scariest bug: one user seeing another's data. Check your auth before someone else does.

That app you built pulls in hundreds of packages you've never read. Find the risky ones.

The #1 vibecoding mistake: API keys sitting in your code or git history. Hunt them down.

Good logs save you at 2am. Bad ones leak data and tell you nothing. Get this right.

Protect user data properly — before a leak makes the decision for you.

Before you let real users in: the checklist that catches what vibecoding skips.

The standard checklist real engineers use. Run your app through it in plain English.

See a UI you like? Describe it and rebuild it instead of starting from a blank page.

A mock interviewer that runs you through a real system design round, interrupts like the real thing, and scores you at the end. Brutal on purpose.

Building against an API that isn't ready? Describe the endpoint — get realistic mock JSON (success and error cases) so you can build the front end now.

Stuck? Explain the problem to it out loud. It asks the questions that make you find your own bug — and only steps in when you're truly stuck.

Practice coding interviews the right way. Paste the problem — it nudges you toward the solution with hints, only revealing the answer once you've actually tried.
