Reviewed session_break impl in using-tasks SKILL.md (commit 9a518fc, v1.2.0).
All 4 acceptance criteria met:
- Rule placement: Task completion step 6, after close (set green + commit),
before any tasks_claim_next — order correct.
- SESSION BOUNDARY message: verbatim match to design string (slug + hint).
- Absent flag: behaviour unchanged (no regression).
- Version: bumped to v1.2.0 in 9a518fc (now 1.3.0 from later archival task).
No blocking findings, no follow-up tasks.
