### Phase 1: Issue Discovery and Planning

... [phase work] ...

**ACTION: Save state after Phase 1 completion:**

Use `save-workflow-state` skill:
- issue_number: $ISSUE_NUMBER
- issue_title: $ISSUE_TITLE
- current_phase: 1
- branch_name: $BRANCH_NAME (if created)
- architecture_plan: Summary from architect agent

→ Proceed to Phase 2
