email-render-builder
Use when the user asks to "build the email HTML", "make this email responsive", "fix dark-mode rendering", or "QA the email across clients"; produces the coded HTML build — a responsive table layout, dark-mode + accessibility pass, a client-render matrix, image-block fallbacks, and a plain-text parity check. Not for writing the copy — use email-creative-builder; not for scoring the email or computing EQS — use email-quality-auditor. 邮件HTML/响应式邮件/暗色模式渲染

What this skill does
Email Render Builder 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. Scope guard: this skill produces the HTML build + render QA + plain-text parity only. It writes no subject-line or body copy (email-creative-builder owns that), scores no SEND dimension, runs no veto, and does not compute the profile-weighted EQS — email-quality-auditor owns all four vetoes (S1/S2/N1/D1) and the EQS rollup. Quick Start Skill Contract Expected output: one email HTML build plus a render-QA report — inline-styled table layout, dark-mode-safe colors, an accessibility checklist result, a client-render matrix (Gmail/Outlook desktop+web/Apple Mail/iOS+Android), image-off fallback notes with bulletproof CTA markup, and a plain-text-parity check against the creative — with the standard handoff summary for memory/email/email-render-builder/. Reads: the approved email creative (subject/preheader/body/CTA and its plain-text alternate) or raw HTML to QA; the destination URL; the mode (promo/cold/newsletter); target client list and any brand color/font/logo constraints; the message-match map from email-creative-builder when present. Writes: a user-facing HTML build (the rendered E/D unit) plus the render-QA report and a reusable handoff summary. …
