Termux SMS

Send SMS text messages directly from the user's Android device using the Termux API. Use this skill when the user asks you to text, SMS, or send a message to a phone number or contact and you are running on (or have SSH access to) their Android phone (e.g., Fold 7) with Termux installed. Do NOT use this for WhatsApp or web-based messaging.

Use termux-sms-send when the user explicitly asks you to send an SMS or text message to a contact or phone number. This skill requires that OpenClaw is running within Termux on an Android device, or that you are executing commands on an Android node via SSH/remote execution where the termux-api package is installed.

Safety & Boundaries

• Require an explicit recipient phone number and message text.
• Confirm the recipient and the exact message text with the user before sending.
• If the user provides a name instead of a number, ask them for the number first (unless you have a contact list reference available).
• Do not spam or send bulk messages.

Usage

To send a text message, use the termux-sms-send command.

termux-sms-send -n <phone_number> "<message_text>"

Examples

Send a simple text:

termux-sms-send -n "[phone]" "Hey, I am running 5 minutes late."

Send a multi-line text:

termux-sms-send -n "5558675309" "Grocery list:
- Milk
- Eggs
- Bread"

Send to multiple numbers (comma-separated):

termux-sms-send -n "+14155551212,5558675309" "Meeting is moved to 3 PM."

Troubleshooting

• If the command fails with a permission error, remind the user that they must install the Termux:API app from F-Droid (or Google Play) and grant it SMS permissions on their Android device.
• Ensure the termux-api package is installed inside the Termux environment (pkg install termux-api).
