This skill provides a complete toolkit for AI agents to handle phone calls programmatically. Agents can:
Create a file at ~/.clawdbot/twilio-config.json:
{
"accountSid": "YOUR_ACCOUNT_SID",
"authToken": "YOUR_AUTH_TOKEN",
"phoneNumber": "+1XXXXXXXXXX"
}Or set environment variables:
export TWILIO_ACCOUNT_SID="YOUR_ACCOUNT_SID"
export TWILIO_AUTH_TOKEN="YOUR_AUTH_TOKEN"
export TWILIO_PHONE_NUMBER="+1XXXXXXXXXX"./scripts/make-call.sh --to "+15551234567" --message "Hello! This is your AI assistant calling."./scripts/setup-webhook.sh --url "https://your-server.com/voice"make-call.sh - Make Outbound CallsMake a phone call with a text-to-speech message:
