Automated browser verification for dev servers. Triggers when a dev server starts to run a visual gut-check with agent-browser — verifies the page loads, checks for console errors, validates key UI elements, and reports pass/fail before continuing.

WhatsApp messaging deep-dive reference. Covers the 24-hour service window rules (free-form vs template mode), sandbox setup for testing, template approval workflow, production sender requirements, and WhatsApp-specific error handling.

Route tasks to agents using Twilio TaskRouter. Covers Workers, Task Queues, Workflows, Reservations, skills-based routing, and common gotchas (hyphen attributes, HAS operator, reservation cascade). Use this skill for any multi-agent contact center, support queue, or AI agent escalation routing.

SMS and MMS deep-dive reference. Covers SMS-specific error codes, message filtering troubleshooting ("Messages Being Filtered or Blocked?" diagnostic checklist), MMS media support (US/CA/AU only), and SMS pumping indicators.

Covers all 11 event types (delivery + engagement), webhook handler implementation, ECDSA signature verification, batched event processing, and common debugging patterns. Use when building SendGrid delivery tracking, engagement analytics, or bounce handling. Requires a SendGrid API key (SG.-prefix) — not applicable to the Twilio Email API (comms.twilio.com).

Manage SendGrid email suppressions: bounces, blocks, spam reports, invalid emails, global unsubscribes, and ASM suppression groups. Covers when and how to remove suppressions, reputation impact, and category-based unsubscribe management. Use when debugging SendGrid delivery issues or building unsubscribe flows. 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).

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).

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 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.

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.
