list-hygiene-monitor
Use when the user asks to "watch my list health over time", "flag decaying / unengaged subscribers on a schedule", "why is my open rate drifting down / bounces creeping up", or "build me a re-permission and prune worklist"; runs the scheduled SEND list-decay + suppression-drift watch — an engagement-recency cohort read (30/90/180/365-day), hard-bounce and spam-complaint trend vs benchmark, suppression-list growth/leakage check, and a segmented re-permission / sunset / prune worklist tied to SEND S (list hygiene) and E (engagement-decay) sub-items. Not for the one-time pre-send authentication pre-flight — use deliverability-qa; not for the consent/suppression record itself — use consent-registry; not for computing the EQS or enforcing vetoes — use email-quality-auditor. 邮件列表健康度监控/退订漂移/沉睡用户清理
Why this skill is useful
Adds domain-specific knowledge for monitoring email list health and engagement decay that the AI wouldn't reliably generate on its own.

What this skill does
List Hygiene Monitor The ongoing hygiene watch, not the pre-flight — a scheduled read of list decay and suppression drift that turns the ESP export into a segmented re-permission / sunset / prune worklist. It cohorts the list by engagement recency (30/90/180/365-day last-open/click), trends hard-bounce and spam-complaint rates against benchmark and the prior baseline, and checks suppression-list growth and leakage — feeding the SEND S (Sender-integrity / Deliverability, list-hygiene sub-item) and E (Engagement, engagement-decay / sunset sub-item) signals. Scope guard: this skill produces the recurring hygiene worklist and the S-hygiene / E-decay reads only; it does NOT run the one-time authentication pre-flight (deliverability-qa), own the consent / suppression record (consent-registry), or compute the profile-weighted EQS / enforce the S1/S2/N1/D1 vetoes (email-quality-auditor). deliverability-qa answers "will this one send land?"; this skill answers "is the list rotting between sends, and who do I re-permission or prune?" — build the worklist here, let the gate render the EQS verdict. Quick Start Skill Contract Expected output: engagement-recency cohorts (30/90/180/365-day active → dormant), a hard-bounce + spam-complaint trend vs benchmark and the prior baseline, a suppression-list growth / leakage read, and a segmented worklist — re-permission (win-back candidates), sunset (drop from active sends), and prune (remove/suppress) — each cohort sized with counts and labeled Measured/Estimated; plus the SEND-S list-hygiene and SEND-E engagement-decay sub-item reads (pass/partial/needs-input) and the standard handoff summary. Reads: the program/list + SEND profile (promotional retention cold-outbound newsletter); an ESP engagement export (last-open / last-click per subscriber, or cohort-level counts) and the ESP bounce/complaint report; a prior baseline (previous hygiene run or an earlier export) for the trend delta; the intended watch cadence (e.g. …
