Produce a structured handover note when the context window fills or the user asks to wrap up. Take the real percentage from /context or, in the Claude desktop app, the get_usage tool; never estimate, and where neither exists record the gap verbatim rather than inventing a figure. Triggers when the context band reaches amber or red, when the user says "wrap up", "handover", or "hand off", or before deliberately ending a long working session.
