5 Scheduled Tasks (Cron) Schedule automated tasks with natural language — cron jobs, delivery options, and the gateway scheduler

Scheduled Tasks (Cron)

Schedule tasks to run automatically with natural language or cron expressions. The agent can self-schedule using the schedule_cronjob tool from any platform.

Creating Scheduled Tasks

In the CLI

Use the /cron slash command:

/cron add 30m "Remind me to check the build"
/cron add "every 2h" "Check server status"
/cron add "0 9 * * *" "Morning briefing"
/cron list
/cron remove <job_id>

Through Natural Conversation

Simply ask the agent on any platform:

Every morning at 9am, check Hacker News for AI news and send me a summary on Telegram.

The agent will use the schedule_cronjob tool to set it up.

How It Works

Cron execution is handled by the gateway daemon. The gateway ticks the scheduler every 60 seconds, running any due jobs in isolated agent sessions:

hermes gateway install     # Install as system service (recommended)
hermes gateway             # Or run in foreground

hermes cron list           # View scheduled jobs
hermes cron status         # Check if gateway is running

:::info Even if no messaging platforms are configured, the gateway stays running for cron. A file lock prevents duplicate execution if multiple processes overlap. :::

Delivery Options

When scheduling jobs, you specify where the output goes:

Option Description
"origin" Back to where the job was created
"local" Save to local files only
"telegram" Telegram home channel
"discord" Discord home channel
"telegram:123456" Specific Telegram chat

The agent knows your connected platforms and home channels — it'll choose sensible defaults.

Schedule Formats

  • Relative: 30m, 2h, 1d
  • Human-readable: "every 2 hours", "daily at 9am"
  • Cron expressions: "0 9 * * *" (standard 5-field cron syntax)

Managing Jobs

# CLI commands
hermes cron list           # View all scheduled jobs
hermes cron status         # Check if the scheduler is running

# Slash commands (inside chat)
/cron list
/cron remove <job_id>
