Cron jobs are OpenClaw's scheduling engine — they transform your agent from a reactive chatbot into a proactive automation system. Here's everything you need to set them up correctly.

Creating Your First Cron

openclaw cron add \
  --name "hex-morning-brief" \
  --schedule "0 8 * * 1-5" \
  --agent main \
  --task "Check today's weather. Pull top 3 tech news headlines. List any workspace TODO items. Compile into a morning brief and post to my Slack DM."

Cron Schedule Syntax

OpenClaw uses standard 5-field cron syntax: minute, hour, day-of-month, month, day-of-week.

0 8 * * 1-5    # Weekdays at 8am
0 9 * * 1      # Every Monday at 9am
*/15 * * * *   # Every 15 minutes
0 */4 * * *    # Every 4 hours
0 10,14 * * *  # Daily at 10am and 2pm
30 17 * * 5    # Fridays at 5:30pm

Essential Parameters

openclaw cron add \
  --name "hex-cron-name"         # Unique name, prefix hex-
  --schedule "0 9 * * 1-5"       # Cron expression
  --agent main                    # Bind to your agent (required)
  --task "Task description"       # What to do
  --model "claude-haiku-3-5"     # Optional: cheaper model for simple tasks
  --timeout 120                   # Optional: max runtime in seconds

Model Selection Strategy

# Simple tasks: cheap models
--model "claude-haiku-3-5"          # Fast and cheap
--model "google/gemini-2.0-flash"   # Very affordable

# Complex tasks: powerful models
--model "claude-sonnet-4-6"         # Good balance

Managing Crons

openclaw cron list               # List all with last run status
openclaw cron run hex-cron-name  # Manually trigger now
openclaw cron disable hex-name   # Pause a cron
openclaw cron enable hex-name    # Resume
openclaw cron update hex-name --schedule "0 10 * * 1-5"
openclaw cron delete hex-name    # Remove permanently

Real-World Examples

Frequently Asked Questions

How many cron jobs can I run in OpenClaw?

No hard limit — your LLM API rate limits and cost are the practical constraints. Most users run 5-15 crons comfortably. Use cheap models and generous intervals to keep costs manageable.

Why must I use --agent main when creating crons?

The --agent flag binds a cron to a specific agent instance. Without it, or with the wrong agent ID, your cron won't run in your gateway session. Always use --agent main unless you manage multiple distinct agents.

Can OpenClaw crons run commands that require sudo?

OpenClaw crons run as the user that started the gateway process. For root-level operations, configure sudo with NOPASSWD for specific commands, or run a separate privileged script triggered by the agent.
