How to Set Up Cron Jobs in OpenClaw for Automated Tasks
Cron jobs are the engine behind autonomous AI agents. They tell your OpenClaw agent to do things on a schedule — check email every 5 minutes, compile daily reports, send weekly follow-ups. Without cron jobs, your agent only reacts to incoming messages. With cron jobs, it becomes a proactive worker that independently manages its responsibilities. This guide shows you how to configure effective cron schedules.
What You Need
- ✓OpenClaw installed with at least one configured agent
- ✓Agent connected to at least one communication channel
- ✓Understanding of what tasks you want automated
Step-by-Step Guide
Understand cron syntax
Cron expressions define when a job runs. The format is: minute hour day-of-month month day-of-week. Examples: "*/5 * * * *" runs every 5 minutes. "0 8 * * *" runs at 8 AM daily. "0 9 * * 1" runs at 9 AM every Monday. Tools like crontab.guru help visualize cron expressions. You do not need to memorize the syntax — bookmark a reference and look it up when needed.
Plan your automation schedule
List the recurring tasks you want automated: email checks (every 5-15 minutes), daily summaries (once in the morning), follow-ups (daily or weekly), report generation (weekly). Consider the cost implications — each cron execution triggers an AI model call. Balance responsiveness against budget.
Configure cron jobs in OpenClaw
In the OpenClaw dashboard, navigate to your agent's scheduling section. Add a new cron job by specifying: the cron expression (schedule), the prompt (what the agent should do when triggered), and the model to use. For cost-sensitive tasks, assign a cheaper model. For important tasks, use your primary model.
Write effective cron job prompts
The prompt for a cron job should be specific and action-oriented. Instead of "check email," write: "Check the inbox for new messages. For customer inquiries, respond with relevant information from your knowledge base. For spam, archive. For messages requiring human attention, forward a summary to the owner." Specific prompts produce specific actions.
Monitor and optimize
Watch your cron jobs for the first week. Check that they run on schedule, produce expected results, and do not waste resources on empty runs (like checking an inbox that rarely gets messages at 3 AM). Adjust frequencies and prompts based on real-world patterns.
Common Mistakes to Avoid
- !Setting cron jobs too frequent for low-volume tasks — every minute is rarely necessary
- !Writing vague cron job prompts that produce inconsistent behavior
- !Not monitoring cron job results during initial deployment
- !Forgetting about time zones — your server time may differ from your business time zone
- !Running expensive models for simple cron tasks — use model routing to save costs

Frequently Asked Questions
How much do cron jobs cost?
Each execution triggers one AI model call. With a cheap model, running every 5 minutes costs about $0.50-2.00/day. Optimize by routing simple cron checks to cheaper models.
Can cron jobs trigger actions in other tools?
Yes. If your agent has the right skills and integrations, cron jobs can trigger actions in any connected service — sending emails, posting updates, querying databases, and more.
