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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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](../deliverability-qa/SKILL.md)), own the consent / suppression record ([consent-registry](../../../protocol/consent-registry/SKILL.md)), or compute the profile-weighted EQS / enforce the `S1`/`S2`/`N1`/`D1` vetoes ([email-quality-auditor](../../deliver/email-quality-auditor/SKILL.md)).** 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?" —… …

How to install
mdr add aaron-he-zhu/aaron-marketing-skills/list-hygiene-monitor@sha256:32191c2285db63acThe line at the top of this page pins the label v20.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
