Form state hook with validation
You need a reusable `useForm` hook in TypeScript that manages field values, touched/dirty state, async validation, and submit handling for a multi-field signup form. You'll delegate the hook to an AI agent. Write the prompt/spec — constraints, edge cases, acceptance criteria — for a first-try-correct result. What does a vague prompt ("make a form hook with validation") get wrong in practice?

[["change|email|a@b.co","change|password|hunter22x","submit","submit"]]out["submits=1"]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.

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.
Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
Run or narrate your approach, then ask the coach.
