Agent Hallucination Disaster: Auto-Reply Bot Sends Wrong Price to Client

Trusttive11 · reddit · 2026-08-05

A non-developer shared a cautionary tale about their AI agent workflow. They had set up an agent to automatically reply to inbound support messages, but it hallucinated a pricing detail and sent it directly to a client before they could intervene.

The incident forced a rethink of agent autonomy: they previously assumed paying for the smartest model meant perfect performance, but realized the real metric is the cost of being wrong. If an error stays internal, it's tolerable; if it reaches a client, it requires rigorous human-in-the-loop checks. They acknowledge this wastes time but currently lack a better solution, prompting a community discussion on supervision strategies.
