More and more people are vibe coding but barely know what got built. You say "add rate limiting" and your AI does it. But do you know what your users actually see when they hit the limit? A friendly message? A raw 429? Does the page just hang?

VibeCheck asks you stuff like that. One question after your AI finishes a task, based on your actual diff. It looks at what was built, compares it to what you asked for, and checks if you know what changed in your product.

Works with any AI coding tool that uses git. Auto-quiz after every commit with a single setup command, or run on-demand whenever you want.

Skip it every time if you want. By default, no scores or answers are saved. Just a quick reality check.
