SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Schedule and manage time-based tasks and reminders using cron-like commands to automate repetitive actions in AI workflows.

Core Features & Use Cases

  • Three modes: Reminder, Task, and One-shot scheduling via cron_add, cron_list, and cron_remove.
  • Flexible timing expressions: supports ISO datetimes (for at), duration-like values (for every), and standard cron expressions (for cron).
  • Safe, deterministic task orchestration with auto-detection of channel, session, and chat context; supports job listing and removal for lifecycle management.

Quick Start

Schedule a one-time reminder for 2026-04-01T09:00:00Z with cron_add label "standup" and prompt "Daily standup reminder".

FAQPage Schema
How do I schedule recurring tasks and reminders using cron expressions?

You can schedule recurring tasks using standard cron expressions via the cron_add command. It also supports interval strings for 'every' and absolute ISO datetimes for one-shot 'at' scheduling to automate reminders.

What is the best way to manage time-based automation for agent workflows?

Time-based automation for agent workflows is managed through cron_add, cron_list, and cron_remove commands, providing deterministic task orchestration with auto-detection of channel, session, and chat context.

Can I set up a one-shot reminder using an absolute ISO datetime?

Yes, you can set up a one-shot reminder using an absolute ISO datetime. By using cron_add with the 'at' mode, you can schedule one-time events like a 2026-04-01T09:00:00Z standup reminder.

How do I list and remove active scheduled jobs?

You can list and remove active scheduled jobs using the cron_list and cron_remove commands. These functions provide lifecycle management for your reminders, recurring tasks, and one-shot events.

Are there safeguards against infinite loops when scheduling tasks?

Yes, the scheduling mechanism includes safeguards against recursion and explicit prompt handling. This ensures safe, deterministic task orchestration across personal workflows or agent orchestrations.
