twilio-send-message

Send messages via Twilio's Programmable Messaging API across all channels — SMS, MMS, RCS, and WhatsApp. Covers text messages, media, rich content (cards, carousels, buttons), template-based sends, Messaging Services, status callbacks, and WhatsApp's 24-hour service window. Use when the user wants to send a message — whether they say "send SMS", "text message", "branded message", "rich message", "WhatsApp message", "RCS message", "notification", or "alert".
