LLM Budget Controls for Cron Agents

Quick answer

Cron agents need per-job budgets, cheap default models, retry limits, terminal status files, and alerts when spend rises without new output. Scheduled work is useful only when it stays visible.

Cron hides standing cost

A single scheduled job can feel free because it is small. Ten jobs running all day become a fixed cost line. The risk is not one run. It is the habit of letting every monitor load too much context forever.

Set a model budget by job type

Heartbeat checks, inbox scans, and status audits should default to cheaper models unless judgment-heavy work is actually needed. Escalation should be explicit and logged.

Retries need a ceiling

Transient errors deserve a retry. Repeating the same failure with the same context does not. Cron jobs should stop after repeated identical failures and write a blocked state that a human or parent agent can inspect.

How Clawback helps

Clawback makes scheduled-agent spend visible by job, so routine background work does not disappear inside a provider dashboard.

FAQ

Should cron agents use the cheapest model?

Use the cheapest model that can do the job reliably. Some tasks need stronger judgment, but many scheduled checks do not.

What is a healthy retry policy?

Retry transient failures, then stop on repeated identical errors with a terminal blocked state.

What should be alerted?

Unexpected model escalation, repeated retries, large token growth, or spending with no output progress.
