Handoff

Prepare for handing off to a new Claude Code session. The goal is to leave a clear trail so the next session can pick up the sprint without re-discovery.

Steps:

1. Read the current sprint doc (docs/sprints/ — find the active one).
2. Update the sprint doc to reflect completed work:
   • Mark finished PRs with their PR number and "Merged" status.
   • Check acceptance criteria boxes.
   • Add an observations section if e2e testing revealed anything notable.
   • Leave upcoming PR specs unchanged (the next session will use them).
3. Read MEMORY.md and check whether it reflects the current state:
   • Sprint status (which PRs are done, which are next).
   • Any new architecture notes from this session's work.
   • Test count if it changed significantly.
   • Update if stale; skip if already current.
4. Check whether any other memory files need updating or creation:
   • New feedback memories (user corrections during this session).
   • New project memories (decisions, constraints discovered).
   • Remove or update memories that are now outdated.
5. Summarize for the user:
   • What was updated.
   • What the next session should start with (next PR from sprint doc).
   • Any open questions or decisions deferred to the next session.

If $ARGUMENTS is provided, treat it as context about what was just completed.
