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...

Security Scan

The skill's requirements and instructions match its stated purpose (sending SMS via Termux) and do not request unrelated credentials or system access.

Purpose & Capability

The skill is explicitly for sending SMS and only requires the Termux binary termux-sms-send; that is proportional and expected for this functionality.

Instruction Scope

SKILL.md limits behavior to sending SMS, requires explicit recipient and message confirmation, and does not instruct reading unrelated files, environment variables, or transmitting data to external endpoints.

Install Mechanism

This is instruction-only (no code files). The SKILL.md metadata includes an apt-based install entry for the termux-api package (a reasonable source inside Termux). Minor inconsistency: the top-level registry reported no install spec while the SKILL.md contains an install hint; otherwise no external download URLs or archive extraction are used.

Credentials

No environment variables, credentials, or config paths are requested; the requested access (a local Termux binary + Android SMS permission) is proportional to sending SMS.

Persistence & Privilege

The skill is not marked always:true and does not request persistent or elevated platform-wide privileges. Autonomous invocation is allowed by default but not combined with other concerning privileges.

Assessment

This skill appears coherent for sending SMS from a device running Termux. Only install/use it if you (or the device owner) have Termux and termux-api installed and you trust the device context. Note: the skill will execute termux-sms-send on the device and requires Android SMS permission—messages may incur carrier charges and reveal phone numbers. Confirm recipients and the exact message before sending, verify Termux:API was installed from a trusted source (F‑Droid or Play Store), and avoid using the skill on devices you do not control.

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).
