Your agent wrote the code.
This finds what it broke.
Paste what Claude Code, Codex, Cursor or Lovable just handed you — or tap a sample if you have nothing to hand. You get the failures AI agents specifically produce, not a style review, and the exact prompt to send back to your agent to fix each one.
Why not just ask the agent that wrote it? Because the model that made the mistake is the one least likely to see it. A second opinion has to come from outside the loop — a different reviewer, hunting a fixed list of known failures, with no memory of why the code was written that way.
Generation got solved. Verification did not.
Every measurement published this year points the same way: agents ship more code, faster, with more holes in it — and the holes get worse with each round of iteration, not better.
- 10×the rate of security findings
- AI-assisted developers commit 3–4× faster than their peers but introduce security findings at 10× the rate, across Fortune 50 codebases.
- 45%of AI-generated code carries an OWASP Top 10 flaw
- Veracode's Spring 2026 GenAI code security study, testing more than 100 models on security-sensitive tasks.
- 35CVEs traced to AI-generated code in a single month
- Georgia Tech's Vibe Security Radar recorded 6 in January 2026, 15 in February and 35 in March — a rising curve, not a plateau.
- 26%of published agent skills contain a vulnerability
- A study of 31,132 AI agent skills found 26.1% contained at least one flaw — prompt injection, data exfiltration or privilege escalation.
Three steps, about a minute.
- 01
Paste the code
A route, a component, a migration — whatever your agent just handed you. No code to hand? Tap a sample and see it work in twenty seconds.
- 02
Read what broke
Every finding names what is wrong, where it is, and what it actually costs you. Free, in full, no signup.
- 03
Send the fix back
Each finding comes with a paste-ready instruction for your own coding agent, so the repair takes one message.
The check is free. The fixes are the product.
You never have to pay to find out what is wrong with your code. You pay to stop doing the repair work by hand.

Learn to catch this yourself.
The catalog explains every failure class and why agents produce it. The course teaches the review loop that catches them before they reach your repo.
