What it does
Agents can't sleep, wait, or run on a schedule. AgentCron gives them time:
- ⏰ Remind later — "Notify me in 2 hours to review the PR."
- 🔁 Recurring — "Email me a summary every weekday at 9am."
- 🪝 Delayed webhook — "POST this URL in 30 minutes to resume the workflow."
- 🔍 Poll — "Every 10 minutes, hit the status webhook."
A scheduled task either notifies you (email / Slack / Discord / webhook) or POSTs to a webhook at the chosen time. One-off or recurring.
> 🔒 Read-only by design. AgentCron only runs the tasks your agent schedules. No access to your inbox, files, or accounts.
