 ## Important Notes
 
-- **Maximum 10 sub-issues**: Don't create more than 10 sub-issues even if the work seems larger
+- **Maximum 5 sub-issues**: Don't create more than 5 sub-issues (as configured in safe-outputs)
 - **Parent Reference**: You must specify the current issue (#${{ github.event.issue.number }}) or discussion (#${{ github.event.discussion.number }}) as the parent when creating sub-issues. The system will automatically link them with "Related to #N" in the issue body.
 - **Clear Steps**: Each sub-issue should have clear, actionable steps
 - **No Duplication**: Don't create sub-issues for work that's already done
