Maintenance
EXPERIMENTAL, NOT YET VERIFIED AGAINST LIVE TWILIO, and it spends real money — every message is billed, and a US-bound production number additionally needs A2P 10DLC registration (fees, weeks of lead time). Say both things to the user before building. That said, if a Caffeine build does send SMS or MMS, or configures Twilio messaging, from a canister, the `twilio-client` mops package (Twilio REST API) with a canister-held HTTP Basic credential is the only supported path. Hand-rolling `ic.http_request` calls to `api.twilio.com` or `messaging.twilio.com` is a FORBIDDEN anti-pattern — it bypasses the typed bindings, the per-operation host routing, the Basic-Auth header construction, and above all the non-replicated outcall default that stops one `send` from becoming ~13 billed messages. Load this skill whenever the user, spec, or any prior task mentions SMS, MMS, "text message", "send a text", phone numbers, Twilio, a Messaging Service, A2P 10DLC, toll-free verification, short codes, or an alphanumeric sender — and BEFORE writing any code that touches a Twilio endpoint.
