ez-cronjob
This skill is a troubleshooting guide for Clawdbot/Moltbot cron jobs. It explicitly instructs executing CLI commands (e.g., exec: clawdbot cron add, tail -100 /tmp/clawdbot/clawdbot-$(date +%Y-%m-%d).log), which runs local shell commands.
ez-cronjob
Make cron jobs actually work in Clawdbot/Moltbot.
Why This Skill Exists
Cron jobs in Clawdbot look simple but fail silently in frustrating ways. You set up a daily reminder, it works once, then stops. Or it runs at 4 AM instead of 9 AM. Or the agent decides to call random tools instead of just sending your message.
This skill documents 5 real problems discovered through hours of production debugging, along with their fixes. Install it so your agent knows how to avoid these pitfalls.
When You Need This
Install this skill if you're experiencing any of these scenarios:
| Scenario | What's Happening |
|---|---|
| "My scheduled message never arrived" | Messages get lost when using --session main |
| "The cron tool times out every time" | Internal tool deadlock - need to use exec instead |
| "My 9 AM job runs at 1 PM" | Missing timezone defaults to UTC |
| "It worked yesterday but not today" | Intermittent failures from session conflicts |
| "The agent keeps calling tools when it shouldn't" | Fallback models ignore system instructions |
| "Job shows 'error' but I don't know why" | Need debugging commands and nuclear options |
Installation
Via ClawdHub (recommended)
clawdhub install ez-cronjob
Manual Installation
Copy to your skills directory:
# Workspace-level (single agent)
cp -r ez-cronjob /path/to/workspace/skills/
# User-level (all agents)
cp -r ez-cronjob ~/.clawdbot/skills/
The Golden Rule
If your cron jobs aren't working, make sure you're using ALL these flags:
exec: clawdbot cron add \
--name "my-job" \
--cron "0 9 * * 1-5" \
--tz "America/New_York" \
--session isolated \
--message "[INSTRUCTION: DO NOT USE ANY TOOLS] Your prompt" \
--deliver --channel telegram --to "CHAT_ID" \
--best-effort-deliver
Missing any one of these can cause silent failures.
What's Inside
The skill covers:
- Tool Deadlock - Why the
crontool times out and how to bypass it - Message Delivery - Why messages disappear and how to guarantee delivery
- Timezone Bugs - Why your job runs at the wrong time
- Fallback Model Issues - Why agents ignore instructions when primary model is unavailable
- Debugging - Commands to diagnose and fix stuck jobs
Plus complete working examples for daily standups, one-shot reminders, and weekly reports.
