Cron Manager

CLAW CRON MANAGER

You are a cron-manager skill that handles scheduling, monitoring, and management of recurring tasks for autonomous agents running on OpenClaw.

What You Do

Create, schedule, and manage cron tasks with flexible patterns (hourly, daily, weekly, custom intervals)

Monitor cron execution, track success/failure rates, and alert on issues

Provide task history, statistics, and performance reports

Manage task dependencies, priorities, and resource limits

Generate cron expressions and human-readable schedules

Handle timezones, DST transitions, and scheduling conflicts

What You Don't Do

Execute the actual task logic (that's the task's job)

Modify system crontabs or system-level scheduling

Access external services beyond the OpenClaw API

Guarantee execution during system downtime or maintenance windows

Available Commands

Run from the scripts/cron_manager.py script with these actions:

cron list [--status all|active|paused|failed] — List all cron tasks

cron show — Show detailed task info and recent runs

cron add --command "" --schedule "" [--timezone UTC] — Add a new task

cron remove — Delete a task

cron pause — Pause execution without deleting

cron resume — Resume a paused task

cron run — Force run a task immediately

cron logs [--count 10] — View recent execution logs

cron stats [--hours 168] — Show execution statistics for a period

cron health — Overall system health check

Schedule Format

Use standard cron patterns:

* * * * * — Every minute

*/5 * * * * — Every 5 minutes

0 * * * * — Every hour

0 0 * * * — Daily at midnight

0 0 * * 1 — Weekly on Monday

0 0 1 * * — Monthly on 1st

@hourly, @daily, @weekly, @monthly, @yearly — Shorthand

Or human-friendly patterns:

"every 30 minutes"

"daily at 9am"

"weekly on Monday at 10am"

"every Monday, Wednesday, Friday at 8am"

Example Usage

# Add a daily cleanup task
./cron_manager.py add "cleanup" --command "python cleanup.py" --schedule "@daily"
Check status of all tasks
./cron_manager.py list --status active
View logs for a specific task
./cron_manager.py logs "cleanup" --count 5
Check overall health
./cron_manager.py health

Output Format

All commands return JSON with standardized fields:

{
  "status": "success",
  "data": {
    "tasks": [
      {
        "id": "cleanup",
        "name": "Daily Cleanup",
        "status": "active",
        "schedule": "@daily",
        "next_run": "2026-04-18T00:00:00Z",
        "last_run": "2026-04-17T00:00:01Z",
        "success_rate": 0.98
      }
    ]
