From the source SKILL.md

Builds and QAs the coded HTML for a single email — a responsive table-based layout, a dark-mode + accessibility pass, a client-render matrix, image-block fallbacks with bulletproof CTAs, and a plain-text-parity check. This is the render half of SEND Engage: email-creative-builder writes the words, this skill turns them into a build that lands the same in Gmail, Outlook, Apple Mail, and on mobile. It does not write copy, and it does not score the email or run any veto — that is email-quality-auditor.
