/session-handoff — Context Transfer

Orientation

Use when ending a session and wanting to preserve context for the next one. Also used automatically by orchestrators (Archon, Fleet) at session boundaries.

Don't use when: You want to extract reusable patterns from a completed campaign (use /learn), write a structured postmortem for a failed campaign (use /postmortem), or produce documentation rather than a context transfer.

Protocol

1. Collect session data (run in parallel):

   • git log --oneline -20 and git diff HEAD --stat
   • Read .planning/campaigns/ for files with status: active
   • Read .planning/fleet/ for files with status: active or needs-continue

2. Identify the primary thread: If an active campaign exists, use its current phase as the anchor. If multiple campaigns are active, list each. If no campaign, use the most recent git commits as the frame.

3. Map data to HANDOFF fields:
