Ping Me

One-shot reminders via natural language. Auto-detects channel and timezone. Say 'remind me...' in any language and get pinged when it's time. Works with every channel.

Set one-shot reminders through natural language. The reminder fires once, delivers to the user's current chat channel, then auto-deletes.

Response flow: Call the script first, then confirm with one short sentence. Keep it concise — no preamble, no time calculations, just the confirmation.

How It Works

User says something like:

• "Remind me in 30 minutes to take a break"
• "提醒我明天下午3点交作业"
• "3分後にお風呂に入ることを思い出させて"
• "rappelle-moi dans 2 heures de rappeler Marie"

You parse the time and message, then call the script SILENTLY.

Channel & Delivery Target

The script auto-detects which channel the user is chatting from.

• You do NOT need to pass --channel unless the user explicitly asks for a different channel
• Only pass --channel when the user explicitly says "remind me on telegram" / "发到飞书" / etc.

Delivery target (--to)

Some channels (e.g. QQ Bot) require a full delivery target for announce mode. The script resolves --to automatically from:

1. $OPENCLAW_TO environment variable (if gateway sets it)
2. $OPENCLAW_SESSION_KEY (extracts target from session key format)
3. config.json → "to" field (user-configured)

If reminders fail with "requires target" error, the user needs to configure their target once:

bash

bash {baseDir}/scripts/ping-me-config.sh --set to=qqbot:c2c:<openid>

You can also pass --to explicitly when calling the script.

Commands

Set a reminder

bash

bash {baseDir}/scripts/ping-me.sh [options] <time> <message>

Time formats:

User says	You pass as <time>
"3分钟后" / "in 3 minutes"	3m
"30分钟后" / "in 30 minutes"	30m
"2小时后" / "in 2 hours"	2h
"明天" / "tomorrow"	1d
"明天下午3点" / "tomorrow at 3pm"	ISO 8601: 2026-03-11T15:00 (no tz offset needed, script uses configured tz)
"周五晚上8点" / "Friday 8pm"	ISO 8601 with calculated date

IMPORTANT: For relative times (N分钟后, N小时后, in N minutes/hours), ALWAYS use the short form (3m, 2h, 1d). Do NOT convert to ISO timestamp.

Options:

• --channel <ch> — override delivery channel (only when user explicitly requests)
• --to <dest> — override delivery target (e.g. qqbot:c2c:<openid>)
• --tz <tz> — override timezone for this reminder
• --emoji <e> — custom emoji prefix

Examples:

bash

bash {baseDir}/scripts/ping-me.sh 30m "Take a break"
bash {baseDir}/scripts/ping-me.sh 2h "Team meeting"
bash {baseDir}/scripts/ping-me.sh "2026-03-11T15:00" "Submit homework"
bash {baseDir}/scripts/ping-me.sh --channel telegram 1d "Renew subscription"

List active reminders

bash {baseDir}/scripts/ping-me-list.sh

Your Job (Agent Instructions)

Creating Reminders

1. Detect reminder intent in any language
2. Extract time and message
3. For relative times → use short form (3m, 2h, 1d). For absolute times → ISO 8601 without tz offset
4. Do NOT pass --channel or --to unless user explicitly requests a specific channel, or the script fails without it
5. Call ping-me.sh with the parsed arguments
6. After the script succeeds, confirm with one short sentence in the user's language

Response Style

Keep responses concise. Call the script first, then confirm briefly:

• "⏰ Got it, pinging you in 30 minutes to take a break."
• "⏰ 好的，3分钟后提醒你洗澡。"
• "⏰ 已设置，明天下午3点提醒你交作业。"
• "⏰ 3分後にリマインドします。"

No need to explain time conversion or timezone logic to the user — just confirm the reminder.

Listing & Cancelling

• "what reminders do I have" / "我有哪些提醒" → run ping-me-list.sh
• "cancel reminder X" / "取消提醒" → run ping-me-cancel.sh <id> (get ID from list first)

Changing Settings (Interactive)

When user wants to change settings, use ping-me-config.sh:

• "change timezone to Tokyo" / "改时区到东京" → --set tz=Asia/Tokyo
• "默认发到飞书" / "send reminders to feishu by default" → --set channel=feishu
• "设置QQ投递目标" → --set to=qqbot:c2c:<openid>
• "show my settings" / "看看设置" → run without args
• "reset settings" / "重置设置" → --reset

After changing settings, confirm with ONE sentence.

First-Time Setup Hint

If the first reminder fails with a "requires target" or "multiple channels" error, guide the user to configure:

1. Default channel: ping-me-config.sh --set channel=qqbot
2. Delivery target: ping-me-config.sh --set to=qqbot:c2c:<openid>

The user's openid can be found in their QQ Bot session key or gateway logs.

Notes

• Reminders auto-delete after firing (--delete-after-run)
• Channel auto-detection: $OPENCLAW_CHANNEL → config → empty
• Delivery target auto-detection: $OPENCLAW_TO → session key extraction → config → empty
• Timezone auto-detection: config.tz → system tz → UTC
• No API keys or external services needed
• Settings stored in {baseDir}/config.json
