Question

You're delegating a distributed rate limiter to an AI agent: it must cap each API key to N requests per rolling minute across a fleet of stateless Go servers backed by Redis. Write the spec. Which algorithm and which guarantees do you pin down, and what would an underspecified prompt let the agent quietly choose wrong?

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.
