Your AI Agent Works Perfectly in the Demo. Here Are the 6 Ways It Dies in Production.

The worked perfectly. You ran it twenty times. You showed it to your team. You showed it to your CTO. Every prompt returned exactly the right output. Then you deployed it. Three days later, a customer reported that the agent gave them completely wrong information - confidently, without any error. Your logs showed HTTP 200s all the way down. Your monitoring reported zero errors. The agent had been silently hallucinating for 72 hours, and nothing in your infrastructure had noticed. This is not a model quality problem. The model was doing exactly what models do.
