The Security Checklist.
AI writes code that works long before it writes code that is safe. Vibe-coded apps get burned by the same seven mistakes, and every one is checkable in an afternoon. For each one you get a diagram of the attack, the fix, and a prompt you can paste into your agent to fix it for you.
What's inside
- Authorization: the single most common hole in vibe-coded apps, and the two-layer fix with Row Level Security
- Never trust the client: why every frontend check is a suggestion, and server-side validation that actually holds
- Rate limiting: what happens when someone calls your AI endpoint 100,000 times tonight, stopped in ten lines
- Supply-chain security: you wrote 2% of the code you ship, here is how to watch the rest
- Logging and monitoring: turn an attack you find out about weeks later into a 3 AM alert and a blocked IP
- Secrets: the two rules that keep API keys out of browsers and git history, and what to do when one leaks
- Backups and recovery: nightly dumps going offsite, plus the restore rehearsal that makes them real
- A one-page pre-launch checklist to run before every ship
