Individual skill
inbox-lifecycle-manager
The weekly keep/cancel/promote/buy loop for a cold email sending fleet. Decides which domains are burned and should be cancelled, which warmed reserves to promote into campaigns, which capacity to demote, and how many new domains to buy — using measured reply, bounce, age and send-volume floors instead of gut feel. Use when asked "which inboxes should I cancel", "what should I replace this week", "my fleet costs too much", "I'm under my send goal", or as the Friday hygiene routine.

# Inbox Lifecycle Manager
**Diagnosis tells you a domain is sick. This skill decides whether it dies.**
Every cold email fleet leaks money in two directions at once: you keep paying for burned domains
that will never reply again, and you run under your send goal because nobody promoted the warmed
reserves sitting idle. This is the weekly loop that fixes both, with an approval gate in the
middle so nothing gets cancelled on a hunch.
**Read-only by default.** The plan step writes nothing, anywhere. Only the apply step, run after
an explicit human "yes", changes a tag, a campaign, or a provider subscription.
