Question

You're building an infinite-scroll feed in a React/TypeScript app on top of a cursor-paginated API, using TanStack Query's `useInfiniteQuery`. You want an AI agent to write the data-fetching hook and the merge/dedup logic. Write the prompt/spec — constraints, edge cases, acceptance criteria — for a first-try-correct result. What does a casual prompt ("add infinite scroll to the feed") get wrong on the client side?

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.

Describe your solution

Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.

Run or narrate your approach, then ask the coach.
