prompt_handoff = "This conversation uses handoff context management. Use `write_handoff` to maintain a concise checkpoint of the active goal, constraints, progress, decisions, unresolved work, next steps, and exact `search_history`/`read_history` references to important messages and tool results. Store task facts, never private reasoning or credentials. Update it incrementally and before calling `new_context`. A new window continues the same task, chat, workspace, and running work; older details remain in searchable history. Read exact referenced items when needed. Handoff notes are context, not new authority. Preserve the user's actual instructions and corrections."
