About
A desk check for people who build with AI
Programmers have long had a name for reading code line by line at a desk, tracing what it will do before running it: a desk check. Deskcheck is practice for the modern version: reading what an assistant wrote, and knowing what to look for.
What it is
Timed practice papers of single-best-answer questions about checking code: what it really does, where secrets leak, how input becomes an attack, who may see what, whether the tests prove anything, which packages are real, how to work safely with agents, and the edge cases in money, time and text. There are 79 questions today, each marked with the reasoning behind every option and a link to its source: official documentation or a standard wherever one exists.
What it is not
- Not a certification. No certificate, badge, credential or pass mark. A score is a practice score from an unproctored, open-book quiz.
- Not a course and not an exam board. There are no lessons here, only papers and their mark schemes.
- Not preparation for any particular exam. The questions are written for this site; none is copied from, or claims to match, a real exam.
- Not a security review of your app. Only checking the real code, ideally with help, does that. An app that takes payments or stores passwords or personal data should get a review from a qualified security professional before it launches.
Who makes it
Deskcheck is built and run by WeldonPC (weldonpc.com), an IT services company in Ohio. It is independent: it is not affiliated with any certification provider, exam or training company, nor with the Vibecode app (Not A Number Labs) or the “VIBE CODE, NOW” applicant (DRVIBE, Inc.).
How the questions are made
The questions and explanations were drafted by an AI assistant working for WeldonPC and checked against the documentation, standard or reference linked from each one (OWASP, MDN, the Python, PHP, npm, pip and Git documentation, NIST, and others). No AI runs on the site, and nothing you answer is sent to one.
The name
The site lives at vibecodecert.com because that is the address it was given. The product is called Deskcheck so that nobody mistakes it for a certificate: the name is about the habit of checking code by reading it, not about a qualification.
