A senior engineer wants the team's shared /review skill to apply her own extra security checklist when she runs it. Her teammates should keep getting the current team version unchanged. What should she do?

Answer: B — Create a personal variant in ~/.claude/skills/ under a different name, like review-sec

Personal customizations go in ~/.claude/skills/, with a different name so they don't affect or get confused with the team's skill. (A) changes the shared skill for everyone. (C) reuses the team skill's name, which makes it unclear which version runs. (D) pushes her personal checklist into always-loaded team configuration.
