Communications — Master Hub
Build chat, WhatsApp, SMS/voice, push, customer support, an omnichannel inbox + AI chatbot, and
advanced email — at staff/principal depth, with real APIs and 2026-current compliance.
How to use this hub
This single skill bundles all 7 communications skills. Each bundled skill's full instructions
live in skills/<name>/GUIDE.md — read the relevant GUIDE.md before acting, then combine
them: a real support product spans chat + WhatsApp + SMS + push + email + helpdesk + bot.
Workflow
- Match the request to one or more skills below; open its
GUIDE.md first.
- Compose. The cross-cutting invariants repeat across every channel — apply them everywhere:
- Verify every inbound webhook (signatures: WhatsApp
X-Hub-Signature-256, Twilio
X-Twilio-Signature, ESP signing) before doing anything.
- Idempotent + at-least-once: dedupe by provider message id; every channel redelivers.
- Consent/opt-in is mandatory (WhatsApp opt-in, TCPA STOP, email one-click unsubscribe, push permission).
- i18n/RTL Arabic: localize at send time,
dir="auto", ICU plurals, per-locale templates.
Bundled skills
- realtime-chat-messaging — Production real-time chat: stateless WebSocket gateway + Redis
Pub/Sub backplane, server-assigned total ordering, idempotent send, delivery/read receipts,
presence, reconnect+replay, fan-out scaling, backpressure, and per-conversation authz.
→ skills/realtime-chat-messaging/GUIDE.md
- whatsapp-business-integration — WhatsApp Cloud API (Graph v25.0): the 24h window vs approved
templates (HSM), per-message pricing (post-2025), interactive buttons/lists/Flows, signed webhooks,
status receipts, opt-in/quality, BSP abstraction, idempotent intake.
→ skills/whatsapp-business-integration/GUIDE.md
- voice-sms-telephony — Programmable SMS/MMS + voice (Twilio et al.): US A2P 10DLC + TCPA
compliance,
X-Twilio-Signature validation, inbound + STOP/HELP, status callbacks, TwiML IVR,
and real-time AI voice via Media Streams.
→ skills/voice-sms-telephony/GUIDE.md
- push-notifications-advanced — Cross-platform push + in-app: Web Push (VAPID), FCM HTTP v1
(legacy retired 2024), APNs token-based auth (.p8 JWT/HTTP2), token pruning, and an orchestration
layer with preferences, quiet hours, dedupe/digest, and email/SMS fallback.
→ skills/push-notifications-advanced/GUIDE.md
- support-helpdesk-system — Zendesk/Intercom-grade helpdesk: ticket state machine + event log,
omnichannel intake, an SLA engine computed in business hours with pause-on-pending + breach
escalation, routing (round-robin/load/skills), macros/automations, KB/deflection, CSAT/CES/NPS.
→ skills/support-helpdesk-system/GUIDE.md
- omnichannel-inbox-chatbot — Unify chat/WhatsApp/SMS/email/social into one inbox + AI agent:
channel adapters, identity resolution, RAG over the KB (grounded + cited), tool-calling with
guardrails, and confidence-gated human handoff with full context + agent-assist.
→ skills/omnichannel-inbox-chatbot/GUIDE.md
- email-integration-advanced — Advanced email: ESP send (Resend/SendGrid/SES), deliverability
(SPF/DKIM/DMARC/BIMI + RFC 8058 one-click unsub + Gmail/Yahoo/Microsoft 2024–2025 rules),
MJML/React Email, inbound parse, IMAP/Gmail/Graph two-way sync, threading, email-to-ticket,
bounce/complaint suppression.
→ skills/email-integration-advanced/GUIDE.md
Typical compositions
- Support platform: omnichannel-inbox-chatbot (brain) + support-helpdesk-system (tickets/SLA) +
realtime-chat-messaging (web chat) + whatsapp/voice-sms/email (channels) + push (agent/customer alerts).
- Transactional comms: email (receipts) + whatsapp (utility templates) + voice-sms (OTP) + push,
all behind one preference/consent layer.
Pairs well with
ai-mcp-master (prompt-engineering-advanced, mcp-builder for the chatbot/voice brain),
business-master (crm-builder for customer-360), backend-api-master (integrations-pro webhooks,
auth/MFA), analytics-master (engagement/deliverability), and ui-master (chat widget + dashboards).
