Why AI agents fail in production and how to reduce harness risk
More than 500 incidents put 88% of root causes in the harness.
Direct answer
AI agents often fail in production because the system around the model breaks. A review of more than 500 documented incidents attributed 88% of root causes to the harness. Atlan's marketing team built 300 skills and 40 agents in six months, then found that changes to one chained skill broke downstream work. The practical response is to control tool access, assign owners, test handoffs, and keep human approval where a wrong action carries real cost.
