Agent worked in demo. Broke in production. How did you prevent losing your team's trust?

Reddit r/AI_Agents News

Summary

The author describes an AI agent that succeeded in demos but failed silently in production due to poor visibility, eroding team trust and prompting a call for advice on effective pre-production testing methods.

My team deployed an agent that worked perfectly in our demo. In production, it failed silently in ways we didn't expect. By the time we fixed it, the team was done. They wanted to go back to deterministic code. Not because the agent failed but because we had zero visibility into what it did or why. So here's my real question: How do you test agents before production so this doesn't happen? Not the frameworks or tools just: what actually made the difference between "we trust this" and "rip it out"? Curious if anyone else has been there.
