wrapup

End-of-session skill that captures session state to HANDOFF.md, appends to the session log, prunes CLAUDE.md of stale/ephemeral content, and optionally updates global memory. Use at the end of any work session for seamless handoffs. Trigger when the user says "/wrapup", "wrap up", "end of session", "session handoff", "save session state", "wrap this up", "let's wrap up", "close out this session".
