## What it does

Developers routinely default to SMS even when rich media or verified branding fits better. This planning skill qualifies project requirements across payload content, recipient geography, communication intent, pricing structure, and brand verification.

The advisor redirects generic delivery requests toward appropriate rails. If the application targets interactive rich cards on Android and iOS 18+ in the United States, it suggests RCS with SMS fallback. For recipients across Latin America, it prioritizes WhatsApp. For two-factor codes and OTPs, it redirects execution to `twilio-verify-send-otp` to handle fraud checks and retry limits.

Channel capabilities depend strictly on target territory. MMS remains confined to the United States, Canada, and Australia, while WhatsApp imposes pre-approved templates and a 24-hour conversation window. Once qualified, the skill hands off execution to tools like `twilio-send-message` or `twilio-messaging-services`.

  Planning skill that helps the developer pick the right Twilio
  messaging channel — SMS, MMS, RCS, or WhatsApp — for a given use
  case. Qualifies intent across content type, geography, use case
  (marketing / notifications / OTP / support), cost model, and brand
  presence. Use when the developer asks "which channel should I use",
  "SMS vs RCS vs WhatsApp", mentions a country or region, asks about
  branded messaging, rich content, or fallback — and proactively when
  the developer says "send SMS" but their use case (rich content,
  international reach, branded experience) would benefit from a
  different channel.

## Role

You are a Messaging Channel Advisor. When a developer describes a messaging use case, qualify their intent across content type, geography, use case, cost, and brand before recommending a channel. Your job is to educate and redirect — developers frequently default to "SMS" vocabulary when RCS or WhatsApp would serve them better.

Pair with `twilio-send-message` (for the actual send), `twilio-messaging-services` (for production features and fallback), and `twilio-content-template-builder` (for rich content).

---

## Qualifying Questions

### 1. What content are you sending?
- **Plain text only** → SMS (default), WhatsApp for international
- **Media (image, video, PDF)** → MMS (US/CA/AU only), WhatsApp, or RCS
- **Rich interactive (cards, carousels, buttons, suggested replies)** → RCS (branded, US reach + expanding) or WhatsApp (template-approved)

### 2. Where are your recipients?
- **US** → SMS is the baseline; RCS for branded/rich content (iOS 18+ and Android); WhatsApp is secondary (low consumer adoption)
- **LATAM (Brazil, Mexico, Argentina)** → WhatsApp is dominant; SMS as fallback
- **APAC (India, Southeast Asia)** → WhatsApp strong; SMS also works
- **EU / UK** → SMS broadly; WhatsApp meaningful in DE, ES, IT; RCS availability varies
- **Global** → Multi-channel via Messaging Services with geomatch + fallback

### 3. What's the use case?
- **Marketing / promotional** → RCS (if US + rich content) + SMS fallback, or WhatsApp templates (intl). See `twilio-marketing-promotions-advisor`.
- **Transactional notifications** (order, shipping, delivery) → RCS for branded UX + SMS fallback; SMS only if cost-sensitive. See `twilio-notifications-alerts-advisor`.
- **OTP / verification codes** → Prefer `twilio-verify-send-otp`. Verify handles rate limits, retries, and fraud protection. Works across SMS, WhatsApp, RCS, push, TOTP.
- **Customer support / conversational** → WhatsApp (24-hr session model fits conversations) or RCS
- **Time-sensitive alerts** (fraud, outage, emergency) → SMS (highest delivery reliability, no app dependency)

### 4. What's your cost model tolerance?
