Setup (check before using)

ruby ~/.claude/skills/twilio/scripts/check_setup.rb

If the output is OK, proceed to the Flow section.

If the output is SETUP_NEEDED, guide the user step by step. Present ONE step at a time, wait for the user to confirm before moving to the next.

Step 1 — Ask the user to get their credentials:

You need your Twilio Account SID and Auth Token. You can find both on the Twilio Console dashboard:

https://console.twilio.com/

Look for Account SID and Auth Token near the top of the page. Copy both values.

Step 2 — When the user pastes the credentials, save them:

ruby ~/.claude/skills/twilio/scripts/save_token.rb 'ACCOUNT_SID' 'AUTH_TOKEN'

If the script outputs an error, the credentials are invalid. Ask the user to double-check and try again.

If setup is not complete, DO NOT proceed to the Flow. Complete all steps first.

Flow

The argument $ARGUMENTS may contain a phone number or message/call SID.

Step 1: Show account info

ruby ~/.claude/skills/twilio/scripts/account.rb

Present the account info to the user and ask what they want to do.

Step 2: Actions

List messages:

ruby ~/.claude/skills/twilio/scripts/messages.rb
ruby ~/.claude/skills/twilio/scripts/messages.rb --to '+15551234567'
ruby ~/.claude/skills/twilio/scripts/messages.rb --from '+15559876543'

Get message details:

ruby ~/.claude/skills/twilio/scripts/message.rb MESSAGE_SID

Send SMS (requires user confirmation):

Ask the user to confirm: "Do you want to send an SMS from FROM_NUMBER to TO_NUMBER with this message?" Only execute after a "yes".

ruby ~/.claude/skills/twilio/scripts/send_sms.rb --from '+15551234567' --to '+15559876543' --body 'Hello from hitank!'

List calls:

ruby ~/.claude/skills/twilio/scripts/calls.rb

List phone numbers:

ruby ~/.claude/skills/twilio/scripts/numbers.rb

Get usage records:

ruby ~/.claude/skills/twilio/scripts/usage.rb

If $ARGUMENTS looks like a phone number, search messages with --to or --from that number. If it looks like a message SID (starts with SM), get message details. If it looks like a call SID (starts with CA), mention it.

Notes

• Pure Ruby, zero gems — stdlib only (json, net/http, uri, fileutils)
• Auth via HTTP Basic Auth (Account SID as username, Auth Token as password)
• Credentials file: ~/.config/twilio/credentials (outside the repo, never commit)
• Stores credentials as account_sid:auth_token
• Sending SMS requires explicit user confirmation
• Twilio API uses form-encoded POST bodies (not JSON)
