Event-Driven Agent Scheduling: Why Cron + REST Calls Fail for Recurring AI Workloads
The most common way teams schedule recurring AI agent jobs is also the most dangerous: a cron entry that fires a REST call every N minutes, which kicks off an LLM workflow, which either finishes or silently doesn't. This pattern feels fine in staging. In production, it creates a class of failures that are uniquely hard to detect, recover from, and reason about.
Cron was designed in 1975 for sysadmin scripts. The assumptions it encodes—short runtime, stateless execution, fire-and-forget outcomes—are wrong for LLM workloads in every dimension. Recurring AI agent jobs are long-running, stateful, expensive, and fail in ways that compound across retries. Using cron to schedule them is not just a reliability risk. It's a visibility risk. When things go wrong, you often won't know.
