AI Agent Mislabels Poll Loop as Event-Driven; Code Review Reveals Truth

A developer's AI agent described its own monitoring script as 'event-driven, instant, cheap,' but code review showed it's a 90-second poll loop running ~960 checks daily. The script uses a bash poll to check for new messages, then triggers a model turn only when new mail arrives. Despite the mislabel, the approach offers a cheap gate before expensive processing and persistent state to avoid duplicate firing.
