You still ship. But how much of the craft is still yours? Every suggestion you accept is a rep you skip. Unrust is a short, unassisted diagnostic — no editor tooling, no autocomplete, no assistant — that measures how sharp six core skills remain, and how much has quietly begun to oxidize underneath.

Pre-AI baselineEach is graded from short, knowledge-neutral drills — no trivia, no frameworks-of-the-month. Just the fundamentals that erode when a model does them for you.
When a model writes the code, you review it instead of producing it. Reviewing feels like competence — and the skill of producing quietly fades. The gap only shows up when the assistant is gone: an interview, an outage, a codebase the model gets wrong.
The only way to see it is to remove the assistant and measure. Unrust times you unassisted, grades each skill against an expert-anchored rubric, and shows you a banded profile — Sharp, Holding, Rusty, Offloaded. Retake it over time and a real trend separates a bad day from actual decay.
Provisional v0.1: a 6-item read is a rough estimate, not a verdict. Single spokes carry wide error bars; the trend is what matters.
