+Clear all subtasks from all tasks globally.
+
+## Global Subtask Clearing
+
+Remove all subtasks across the entire project. Use with extreme caution.
+
+## Execution
+
+```bash
+task-master clear-subtasks --all
+```
+
+## Pre-Clear Analysis
+
+1. **Project-Wide Summary**
+   ```
+   Global Subtask Summary
+   ━━━━━━━━━━━━━━━━━━━━
+   Total parent tasks: 12
+   Total subtasks: 47
+   - Completed: 15
+   - In-progress: 8
+   - Pending: 24
+   
+   Work at risk: ~120 hours
+   ```
+
+2. **Critical Warnings**
+   - In-progress subtasks that will lose work
+   - Completed subtasks with valuable history
+   - Complex dependency chains
+   - Integration test results
+
+## Double Confirmation
+
+```
+⚠️  DESTRUCTIVE OPERATION WARNING ⚠️
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+This will remove ALL 47 subtasks from your project
+Including 8 in-progress and 15 completed subtasks
+
+This action CANNOT be undone
+
+Type 'CLEAR ALL SUBTASKS' to confirm:
+```
+
+## Smart Safeguards
+
+- Require explicit confirmation phrase
+- Create automatic backup
+- Log all removed data
+- Option to export first
+
+## Use Cases
+
+Valid reasons for global clear:
+- Project restructuring
+- Major pivot in approach
+- Starting fresh breakdown
+- Switching to different task organization
+
+## Process
+
+1. Full project analysis
+2. Create backup file
+3. Show detailed impact
+4. Require confirmation
+5. Execute removal
+6. Generate summary report
+
+## Alternative Suggestions
+
+Before clearing all:
+- Export subtasks to file
+- Clear only pending subtasks
+- Clear by task category
+- Archive instead of delete
+
+## Post-Clear Report
+
+```
+Global Subtask Clear Complete
+━━━━━━━━━━━━━━━━━━━━━━━━━━━
+Removed: 47 subtasks from 12 tasks
+Backup saved: .taskmaster/backup/subtasks-20240115.json
+Parent tasks updated: 12
+Time estimates adjusted: Yes
+
+Next steps:

+- Check project timeline
+```
