What evidence does `/skill-doctor` provide, and what are its current limits? --- `/skill-doctor` reports context cost for visible skills and flags skills that have never been invoked. It requires Claude Code v2.1.252 or later, excludes bundled and enterprise skills, depends on feature-flag fetching, and is unavailable through Remote Control. Treat the unused flag as a review signal and combine it with representative sessions, dependencies, and risk.
