he hard part of voice AI agents is not building the first demo. It is handling the cases your training data did not cover. We run multi-agent systems daily and the pattern is always the same. Happy path works great on day one, then edge cases pile up for months. Having a clear escalation path to a human like you did is the right call
We caught a payment module last week where AI wrote it, tests passed, happy path looked fine. No error handling, no idempotency key. Senior dev flagged it in a minute. A vibe coder would have shipped it. The real skill is knowing when AI output is wrong, notprompting fast
