CursorBench · 2026-09-22 ↗Patch review example: why does an empty array slip through?
Editorial example, not measured model output. Review boundary contracts and regression tests; this is not a model ranking.
export function mean(values: number[]) {
return values.reduce((a, b) => a + b, 0)
/ values.length;
}
// mean([]) => NaN
// Missing an explicit empty-input contract⚙️ Select Modelo1 vs Claude Opus 5.5
