SMS Skill (Twilio)

Send and manage SMS messages using the Twilio API.

Prerequisites

Set these environment variables (or in the amp-life-agent .env):

• TWILIO_ACCOUNT_SID — Your Twilio Account SID
• TWILIO_AUTH_TOKEN — Your Twilio Auth Token
• TWILIO_PHONE_NUMBER — Your Twilio phone number (e.g., +14155551234)
• MY_PHONE_NUMBER — Abhi's real phone number

Sending an SMS

Use curl to send via Twilio REST API:

$accountSid = $env:TWILIO_ACCOUNT_SID
$authToken = $env:TWILIO_AUTH_TOKEN
$from = $env:TWILIO_PHONE_NUMBER
$to = $env:MY_PHONE_NUMBER

$body = "Your message here"

$pair = "${accountSid}:${authToken}"
$bytes = [System.Text.Encoding]::ASCII.GetBytes($pair)
$base64 = [System.Convert]::ToBase64String($bytes)

Invoke-RestMethod -Uri "https://api.twilio.com/2010-04-01/Accounts/$accountSid/Messages.json" `
  -Method POST `
  -Headers @{ Authorization = "Basic $base64" } `
  -Body @{ To = $to; From = $from; Body = $body }

Receiving SMS

To receive SMS, set up a Twilio webhook pointing to a publicly accessible endpoint. For local development, use ngrok or a cloud function.
