Reminder Engine

Create, list, cancel, and snooze reminders using OpenClaw cron jobs (one-shot or recurring). Use when a user asks things like: 'remind me in 20 minutes', 'remind me tomorrow at 9', 'every weekday at 10:30', 'list my reminders', 'cancel reminder', or 'snooze this'. This skill focuses on safe scheduling (timezone-correct), confirmation before creating jobs, and clean reminder text that will read well when it fires.

Turn natural-language reminders into OpenClaw cron jobs.

Workflow

1) Parse intent

Classify the request:

• One-shot: “in 20 minutes”, “tomorrow at 9”, “on March 1st at 10:00”
• Recurring: “every day at 9”, “every weekday at 10:30”, “every Monday”, “every 2 hours”
• Management: “list reminders”, “cancel X”, “disable/enable”, “snooze X”

Extract:

• reminder text (what should be said when it fires)
• delivery channel context (current chat unless user specifies otherwise)
• timezone (default to the runtime timezone unless user specifies)

2) Confirm schedule (always)

Before creating/updating/removing jobs, echo back:

• the computed schedule in human form (and timezone)
• whether it’s one-shot or recurring
• the exact reminder message text

If the user’s wording is ambiguous (“next Friday”, “in the morning”), ask a single clarifying question.

3) Create the cron job (reminders)

Use the cron tool.

Rules:

• Prefer schedule.kind="at" for one-shots.
• Prefer schedule.kind="cron" for recurring reminders (use tz when possible).
• Use sessionTarget="main" and payload.kind="systemEvent".
• Write payload text like a reminder: start with “Reminder:” (especially if the reminder is set far in advance).
• Include light context if it helps (“Reminder: submit the invoice (you said you need this for the client call)”).

4) List / cancel / snooze

• List: use cron.list, show jobId + next run + name/summary.
• Cancel: cron.remove(jobId) (prefer cancelling by exact jobId; if user provides text, search list and confirm).
• Snooze: implement as cancel+recreate (one-shot) or a one-shot override reminder.

Reminder text quality

• Keep it short and action-oriented.
• Avoid secrets.
• If the reminder is for a public channel, warn the user.

Safety

• Never create spammy recurring reminders without explicit confirmation.
• Never “broadcast” reminders to multiple targets unless explicitly requested.
• Never include access keys/tokens in reminder payloads.

Examples (what good looks like)

User: “remind me in 20 minutes to stretch”

• Create one-shot at job.
• Payload text: Reminder: stretch.

User: “every weekday at 10:30 remind me to stand up”

• Create recurring cron job in local timezone.
• Payload text: Reminder: stand up (weekday standup alarm).

User: “list my reminders”

• List jobs; show ids so the user can say “cancel ”.

User: “cancel the stand up reminder”

• List matching jobs, ask which one if multiple, then remove.
