# Muse

> Generate a retrospective markdown for an archived (or about-to-be-archived) mumei feature. Reads requirements / design / tasks / spec-reviews / reviews / cost-log and emits muse.md with AC count, Wave count, review iter counts, fix-spiral detection, token cost, cache hit rate, and hook firing breakdown. Triggered by the user invoking /mumei:muse <feature after /mumei:shelve (or before, if explicitly requested). Read-only with respect to feature content; writes only the muse.md output file.
