Find aged [D] artifacts whose invalidation triggers may have fired. Scans vault _context.md tables, parses the invalidates-if clause, scores decay from git log keyword search + vault contradiction + age. Emits ranked candidates with the triggering signal. User confirms → artifact marked superseded. Triggers: "decay check", "what's stale", "memento decay", "find stale decisions", "audit aged artifacts".

From the source SKILL.md

Walk every [D] artifact past its freshness window, look for evidence the invalidation trigger has fired, prompt the user to mark stale ones superseded.
