What Is a Cron Job in OpenClaw? Scheduled AI Agent Tasks Explained
Definition
A cron job in OpenClaw is a scheduled task that runs automatically at specified intervals. Borrowed from the Unix scheduling system, cron jobs tell your AI agent to perform specific actions on a regular schedule — checking email every 5 minutes, generating daily reports, sending weekly follow-ups, or performing monthly data cleanup. This scheduling capability transforms AI agents from reactive responders into proactive workers that execute tasks independently.
How It Works
OpenClaw uses standard cron syntax to define schedules. You configure a cron expression (like "*/5 * * * *" for every 5 minutes) and pair it with an instruction for the agent. When the schedule triggers, OpenClaw activates the agent with the specified prompt. The agent then executes the task using its AI model, memory, and integrations. For example, a cron job might check the email inbox every 5 minutes, process new messages, and take appropriate action based on the agent's Soul.md instructions.
Why It Matters
Cron jobs are what make AI agents truly autonomous. Without scheduling, agents only respond when triggered by external events. With cron jobs, agents proactively monitor, check, process, and act on their own schedule. This is the difference between an AI that waits for your command and an AI employee that independently manages its workload throughout the day.
Real-World Example
A business owner configures three cron jobs for their OpenClaw agent: (1) Check email inbox every 5 minutes and respond to customer inquiries. (2) Every morning at 8 AM, compile a summary of yesterday's customer interactions and email it to the owner. (3) Every Friday at 5 PM, send follow-up messages to leads who have not responded in 3 days.

Frequently Asked Questions
How often can cron jobs run in OpenClaw?
As frequently as every minute, though most practical use cases run every 5-15 minutes to balance responsiveness with AI model costs.
Do cron jobs cost money each time they run?
Each cron job execution triggers an AI model API call, which has a small cost. Running a job every 5 minutes costs roughly $0.50-2.00 per day depending on task complexity and model choice.
