Planning skill for marketing and promotional messaging. Qualifies the developer's campaign needs across channel selection, compliance, audience segmentation, and delivery tracking to recommend the right Twilio messaging architecture. Handles both "set up a promotional SMS campaign" and "build a multi-channel engagement pipeline with Segment integration."

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.

Twilio Messaging channel overview and onboarding guide. Covers all channels (SMS, WhatsApp, RCS, Facebook Messenger), the unified Messages API, channel selection guidance, and the recommended setup sequence from first message to production monitoring. Start here before choosing a specific messaging channel.

Create and configure Twilio Messaging Services for production messaging. Covers sender pools, geo-match, sticky sender, message scheduling, compliance toolkit, SMS pumping protection, link shortening, and intelligent alerts. Use this skill when setting up production-ready messaging infrastructure.

Receive and respond to inbound messages and track outbound delivery status via Twilio webhooks — across SMS, MMS, WhatsApp, and RCS. Covers webhook request parameters, replying with TwiML, validating webhook signatures for security, and handling status callbacks. Use this skill whenever an agent needs to handle incoming messages on any channel or track outbound message delivery in real time.

Planning skill for transactional notifications, alerts, and reminders. Qualifies the developer's needs across urgency, channel selection, delivery confirmation, and fallback patterns to recommend the right Twilio notification architecture. Handles both "send shipping updates to customers" and "build a multi-channel alert system with delivery confirmation and fallback."

Choose the right Twilio number type and sender BEFORE building. Covers phone numbers (local, toll-free, short code, mobile), alphanumeric sender IDs, WhatsApp senders, RCS agents, international availability, and regulatory bundles. Each number type has its own compliance program — choosing wrong means rebuilding. Use this skill first.

Set up and manage Twilio Organizations for centralized account and user governance. Covers the Organization > Account > Subaccount hierarchy, roles (Owner/Admin/Standard), managed vs independent accounts, domain registration, SSO enforcement, SCIM provisioning, and Organization merging. Use this skill when managing multiple Twilio accounts or users across teams.

Send RCS Business Messages via Twilio. Covers compliance onboarding (7-part US process), sender profile setup, sending rich cards and carousels, SMS fallback, device support (Android + iOS 18 caveats), and common errors. Use this skill when building RCS messaging or onboarding an RCS sender.

Manage regulatory compliance for international phone numbers. Covers what bundles are, which countries require them, how to create End-Users and Supporting Documents, evaluate and submit bundles, fix evaluation failures, update bundles when regulations change, and ISV multi-account patterns. Use this skill when provisioning numbers outside the US.

Handle rate limits, retries, and failures when building on Twilio at scale. Covers 429 exponential backoff with jitter, per-number throughput limits, StatusCallback resilience, thin-receiver pattern, and fallback chains. Use this skill whenever sending messages or making calls at volume, or when building production-grade Twilio integrations.

Choose the right Twilio authentication method and implement it correctly. Covers Auth Token (testing only), API Keys (production standard), OAuth2 client_credentials (time-limited bearer tokens), Access Tokens (client-side SDKs), and test credentials. Use this skill before making any Twilio API calls in production.

Configure Twilio accounts for HIPAA compliance. Covers BAA requirements, HIPAA Project designation (self-service and support), eligible services list, per-product requirements (Voice, SMS, ConversationRelay, Conversation Intelligence, Flex, Verify), message redaction, and what is NOT eligible. Use this skill when developers are building healthcare workflows on Twilio.

Secure Twilio applications against common attacks. Covers credential management (API keys vs auth tokens), request validation (webhook signature verification), PCI DSS compliance, HIPAA account requirements, SMS pumping prevention, geo-permissions, and account isolation patterns. Use this skill when developers are building or deploying Twilio apps.

Set up a SendGrid account for email delivery. Covers API key creation (SG.-prefix), domain authentication (DKIM/SPF via CNAME records), Single Sender Verification for testing, SDK installation, and the relationship between SendGrid and Twilio credentials. Use before any other SendGrid skill. This skill is for SendGrid only — not the Twilio Email API (comms.twilio.com).

Diagnostic and advisory skill for email deliverability problems. Use when a developer asks why emails are going to spam, not reaching the inbox, getting blocked, bouncing, or how to improve sender reputation — with or without a specified platform. Covers SendGrid-specific tooling: SPF, DKIM, DMARC, BIMI, IP warmup, list hygiene, bounce/spam rate thresholds, and Engagement Quality Score (SEQ). Do NOT use for Twilio Email (comms.twilio.com / Account SID + Auth Token) — use twilio-email-deliverability-advisor instead. Do NOT use for general email sending questions — use twilio-sendgrid-email-send (SendGrid) or twilio-email-deliverability-advisor instead.

Send transactional and bulk email via the SendGrid v3 Mail Send API. Covers single sends, personalized batch sends with dynamic templates, scheduled sends with cancellation, attachments, and sandbox mode for testing. Use this skill when the caller has a SendGrid API key (SG.-prefix). Do NOT use this skill if the caller is using the Twilio Email API (comms.twilio.com) — that is a separate product with different credentials.

Configure SendGrid dynamic templates (Handlebars), tracking settings (opens, clicks, subscriptions), link branding for custom tracking domains, and content types (HTML, plain text, AMP). Use when customizing SendGrid email content, tracking behavior, or branded links. Requires a SendGrid API key (SG.-prefix) — not applicable to the Twilio Email API (comms.twilio.com).

Monitor email program health with SendGrid Engagement Quality (SEQ) scores. Covers the SEQ API endpoints, the 5 scoring metrics (engagement recency, open rate, bounce classification, bounce rate, spam rate), eligibility requirements, and interpreting scores for deliverability improvement. Use when diagnosing SendGrid deliverability issues or monitoring sender reputation. Requires a SendGrid API key (SG.-prefix) — not applicable to the Twilio Email API (comms.twilio.com).

Receive inbound email via SendGrid Inbound Parse webhook. Covers MX record setup, parsed vs raw mode, handling attachments, and common pitfalls. Use when building email-to-app workflows like support ticket creation or email processing pipelines. Requires a SendGrid API key (SG.-prefix) — not applicable to the Twilio Email API (comms.twilio.com).
