A simple test: is it worth it?
Ask three questions. Is the input different every time? Does a human decide by the same rules each time? Can a mistake be undone in a minute?
Three yeses — agent. One no — a script, a form or a rule. That is not a worse answer, just a cheaper and duller one.
Examples that hold up
Service inbox triage: the agent reads the ticket, classifies the fault, assigns the right technician and drafts a reply. The human clicks send.
Filling in workshop jobs: the mechanic dictates two sentences, the agent turns them into a description, a parts list and an estimate. Five minutes saved per job, a dozen times a day.
Safety rails we never skip
The agent gets only the permissions it needs — not the keys to everything. It has a step limit, a cost limit and a clear line between what it may do and what it may only propose.
Everything it does is logged. When something goes wrong — and it will — you want to see exactly where it slipped, not guess.
Start with one process
Pick the one task that eats the most time and pleases nobody. Measure how long it takes today. Run an agent on it for two weeks and measure again. If the numbers do not move, nothing changed.
