description: Session handoff — update PROGRESS.md, PLAN.md, and write the history file in one go before ending a work session.
allowed-tools: Read, Write, Edit, Bash
---

Prepare a clean handoff so the next agent can pick up.

Steps:

1. Read `PROGRESS.md` and `PLAN.md`. If either is missing, create a skeleton.
2. Ask the user (or infer from the session) what was completed, what is in progress, and what is blocked.
3. Update `PROGRESS.md`:
   - Move completed items to "Done" with date and artifact paths.
   - Mark in-progress items with current owner and status.
4. Update `PLAN.md`:
   - Remove completed items.
   - Add any newly discovered follow-ups.
   - Re-order priorities if needed.
5. Write `docs/history/YYYY-MM-DD_{작업명}.md` with **소요 시간**, **Context 사용량**, 이슈 번호, 산출물.
6. Confirm all three files are saved and list their paths.

Arguments: `$ARGUMENTS` — optional short description to seed the history file title.
