Question

You're delegating a password-reset flow to an AI agent (email a reset link, user sets a new password) in a Node app. Write the spec so the agent produces something secure. What security constraints and acceptance criteria must be explicit, and what does a generic 'add forgot-password' prompt get unsafe?

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.
