You still ship. But when an assistant handles more of the implementation, can you still produce, trace, and debug the code on your own? Unrust is a short, timed diagnostic — no editor tooling, no autocomplete, no assistant — that gives you a snapshot of six core coding skills today.

Reference rangeEach is graded from short, knowledge-neutral drills — no trivia, no frameworks-of-the-month. They are core fundamentals worth checking when you want to see how your unassisted work holds up.
AI coding tools can shift more work into review. That can make it harder to tell which skills still feel automatic when you need to produce or debug code without assistance.
Unrust removes the assistant for a short, timed session and grades six skills against an expert-anchored rubric. One session is a snapshot, not a verdict: it cannot distinguish skill decay from unfamiliarity or a bad day. Retake it over time to compare a more useful trend.
A 6-item read is a rough estimate, not a verdict. Single spokes carry wide error bars; the trend is more informative than any one result.
Your diagnostic score is always free. A subscription unlocks the daily practice loop, the full drill library, per-skill mastery, and your saved trend over time.
