A maintenance agent for alarm triage got the cause, priority and parts right on 17 of 20 alarms, and its author lists the 3 misses
It triages alarms on CNC spindles and air compressors, checks the storeroom and drafts the work order, with no AI model call in the alarm path. The misses are the useful part: one was a failed sensor reading 131 C that the rules read as cooler fouling.
For maintenance planners and reliability engineers: copy the method, which is test the agent on real alarms and write down where it was wrong.
