Question

An AI agent wrote a Rust function `chunk<T>(items: Vec<T>, size: usize) -> Vec<Vec<T>>` that splits a vector into fixed-size chunks. It compiles and the basic case looks right. You don't want to read the indexing logic line-by-line. What quick check do you write to confirm it's correct, and which inputs matter most?

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
