Qualifies intent across content type, geography, use case\n  (marketing / notifications / OTP / support), cost model, and brand\n  presence.

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.\n\nPair with `twilio-send-message` (for the actual send), `twilio-messaging-services` (for production features and fallback), and `twilio-content-template-builder` (for rich content).\n\n---\n\n## Qualifying Questions\n\n### 1. What content are you sending?\n- **Plain text only** → SMS (default), WhatsApp for international\n- **Media (image, video, PDF)** → MMS (US/CA/AU only), WhatsApp, or RCS\n- **Rich interactive (cards, carousels, buttons, suggested replies)** → RCS (branded, US reach + expanding) or WhatsApp (template-approved)\n\n### 2. Where are your recipients?\n- **US** → SMS is the baseline; RCS for branded/rich content (iOS 18+ and Android); WhatsApp is secondary (low consumer adoption)\n- **LATAM (Brazil, Mexico, Argentina)** → WhatsApp is dominant; SMS as fallback\n- **APAC (India, Southeast Asia)** → WhatsApp strong; SMS also works\n- **EU / UK** → SMS broadly; WhatsApp meaningful in DE, ES, IT; RCS availability varies\n- **Global** → Multi-channel via Messaging Services with geomatch + fallback\n\n### 3. What's the use case?\n- **Marketing / promotional** → RCS (if US + rich content) + SMS fallback, or WhatsApp templates (intl). See `twilio-marketing-promotions-advisor`.\n- **Transactional notifications** (order, shipping, delivery) → RCS for branded UX + SMS fallback; SMS only if cost-sensitive. See `twilio-notifications-alerts-advisor`.\n- **OTP / verification codes** → Prefer `twilio-verify-send-otp`. Verify handles rate limits, retries, and fraud protection. Works across SMS, WhatsApp, RCS, push, TOTP.\n- **Customer support / conversational** → WhatsApp (24-hr session model fits conversations) or RCS\n- **Time-sensitive alerts** (fraud, outage, emergency) → SMS (highest delivery reliability, no app dependency)\n\n### 4. What's your cost model tolerance?\n- **SMS** — per-message pricing, varies by region; predictable\n- **MMS** — higher per-message than SMS\n- **RCS** — varies by region + content type (Basic vs. Rich)\n- **WhatsApp** — conversation-based (24-hr window free-form; templates charged per conversation)\n\n### 5. Does brand presence matter?\n- **Yes (branded sender, logo, verified)** → RCS in the US, or WhatsApp Business (green tick) internationally\n- **Cross-OS branded** (reach iPhone + Android with one experience) → RCS (now supported on iOS 18+ and Android) with SMS fallback for older devices\n\n---\n\n## Common User Vocabulary Translations\n\nDevelopers often use loose vocabulary. Translate before recommending.\n\n| User says | Often means | Likely best channel |\n|-----------|-------------|---------------------|\n| \"Send an SMS\" | Message to a phone | SMS — unless rich content, branded, or international |\n| \"Text message\" | Same as SMS | SMS — educate if rich or branded needed |\n| \"Branded message\" | Brand visible to user | RCS (US) or WhatsApp (intl) |\n| \"Rich message\" | Cards / buttons / media | RCS or WhatsApp template |\n| \"Show my logo\" | Branded sender | RCS (not a phone number feature) |\n| \"OTP\" / \"verification code\" | Auth / 2FA | `twilio-verify-send-otp`, not raw messaging |\n| \"WhatsApp them\" | Outbound to recipient | WhatsApp — check 24-hr session |\n| \"Reach iPhone and Android\" | Cross-device parity | RCS with SMS fallback |\n| \"International\" | Outside US | WhatsApp in LATAM/APAC; SMS elsewhere |\n| \"Bulk send\" / \"mass send\" | Broadcast-style | Messaging Services + channel-per-region via geomatch |\n\n---\n\n## When to Push Back\n\nIf the developer says \"send SMS\" but the context suggests otherwise, raise the alternative before proceeding:\n\n- **Rich content described** (cards, buttons, images beyond simple media) → suggest RCS + SMS fallback\n- **Recipients in Brazil, Mexico, India, or other WhatsApp-dominant markets** → suggest WhatsApp\n- **OTP / verification use case** → redirect to `twilio-verify-send-otp`\n- **Brand presence / trust is material** (financial, healthcare, enterprise customer) → suggest RCS for US, WhatsApp Business for intl\n- **\"Reach iPhone and Android with the same experience\"** → RCS is the answer\n\nFrame it as an education, not a correction: \"SMS will work — but given [X], RCS would give you [Y]. Would you like to use RCS with SMS fallback?\"\n\n---\n\n## Output Format\n\nWhen you recommend a channel, include:\n1. **Primary channel** and why it fits\n2. **Fallback channel** (if applicable) and how to configure it\n3. **Next skill to invoke** (usually `twilio-send-message` for the send, `twilio-messaging-services` for pool / fallback setup)\n4. **Trade-offs the developer should know** (cost, setup time, approval requirements)\n\n---\n\n## Next Steps\n\n- **Send the message:** `twilio-send-message`\n- **Channel overview and unified API:** `twilio-messaging-overview`\n- **Sender pools + RCS→SMS fallback:** `twilio-messaging-services`\n- **Rich content templates:** `twilio-content-template-builder`\n- **RCS-specific onboarding and rich cards:** `twilio-rcs-messaging`\n- **WhatsApp-specific onboarding:** `twilio-whatsapp-send-message`, `twilio-whatsapp-manage-senders`\n- **OTP / verification flows:** `twilio-verify-send-otp`\n- **Marketing-specific planner:** `twilio-marketing-promotions-advisor`\n- **Notifications-specific planner:** `twilio-notifications-alerts-advisor`\n"
