openclaw-reminder_skill

Overview

This skill creates one-time reminder tasks using OpenClaw cron and returns the result through Discord. Users can request reminders in natural language (relative or absolute times) and the skill schedules a cron job that announces the reminder to the original Discord channel.

How this skill works

The skill parses the user's natural-language time (relative like "in 30 minutes" or absolute like "3pm") and converts it to an ISO 8601 timestamp. It validates and sanitizes the user-provided task content, then creates an OpenClaw cron job using the main session and a system-event so the result is announced back to the correct Discord channel. The job is set to delete itself after running.

When to use it

• Quick one-off reminders sent back to a Discord channel
• Short-term reminders (seconds, minutes, hours, up to ~48 hours)
• When you want the skill to post the reminder result directly in the original channel
• When you need a lightweight cron-based task without a calendar entry

Best practices

• Provide clear, concise task text (avoid long multi-step instructions)
• Specify times understandable in plain language ("in 30 minutes", "tomorrow 9am", "3pm")
• Keep reminders within 48 hours; suggest using a calendar for longer schedules
• Avoid characters and commands that may be rejected (see sanitize step) and rephrase if rejected
• Always run with the main session + system-event so delivery goes to the right Discord context

Example use cases

• User: "remind me to check the oven in 30 minutes" → cron job posts reminder to the same Discord channel
• User: "remind me at 3pm to join the meeting" → schedules a one-time 3pm announcement
• User: "remind me to backup logs in 2 hours" → runs a concise task message that returns to Discord
• Short-term alerts during live chats, demos, or timed follow-ups
