About this skill

Overview

Use when the user asks to "run a deliverability pre-flight before I send", "check my SPF/DKIM/DMARC/BIMI", "why am I landing in spam / promotions", or "score my sender reputation and list hygiene"; runs the ONE-TIME pre-send SEND S1 authentication pre-flight and builds the SEND S (Sender-integrity / Deliverability) evidence read — DNS + DMARC-RUA auth, domain/IP reputation, inbox placement, content/link/render, and point-in-time bounce/complaint hygiene — using Pass/Partial/Fail/Unknown/N/A states and scoring only at complete applicable coverage. Not for the recurring hygiene trend — use list-hygiene-monitor; not for final EQS or veto verdicts — use email-quality-auditor; not for segments/suppression lists — use list-segment-builder. 邮件送达率预检/SPF DKIM DMARC认证/发件域声誉

Evaluation

AI-evaluated 2026-09-03: Exceptionally detailed pre-flight contract with Pass/Partial/Fail/Unknown states, profile weights, scope guards, scripts (doh.py, resend.py) and explicit never-pass-by-default verification. Heavily coupled to a bespoke SEND/EQS framework and sibling skills, which narrows drop-in usability; security is strong with untrusted-data handling, keyless-first inputs, and consent-gated memory writes.
