Decide whether to adopt an agent-written rate limiter

Your company needs per-customer rate limits across 20 Go services that share a Redis cluster. A teammate had an agent write a token bucket library in an afternoon: 400 lines, a Lua script, a local fallback and green tests. They want every service to adopt it next sprint.

Do you adopt the agent's library? Decide what you use, what the agent's work is still good for, and defend the call.
