Write a structured, timestamped handoff document that captures the current session's context (what was done, what changed, key learnings, next steps) so a fresh agent session can resume the work without replaying the prior conversation. Use when the user says "create a handoff", "save a handoff", "write a status.md", "end-of-session summary", "save session context", or wants to wrap up a working session so it can be picked up later.
