+Expand all pending tasks that need subtasks.
+
+## Bulk Task Expansion
+
+Intelligently expands all tasks that would benefit from breakdown.
+
+## Execution
+
+```bash
+task-master expand --all
+```
+
+## Smart Selection
+
+Only expands tasks that:
+- Are marked as pending
+- Have high complexity (>5)
+- Lack existing subtasks
+- Would benefit from breakdown
+
+## Expansion Process
+
+1. **Analysis Phase**
+   - Identify expansion candidates
+   - Group related tasks
+   - Plan expansion strategy
+
+2. **Batch Processing**
+   - Expand tasks in logical order
+   - Maintain consistency
+   - Preserve relationships
+   - Optimize for parallelism
+
+3. **Quality Control**
+   - Ensure subtask quality
+   - Avoid over-decomposition
+   - Maintain task coherence
+   - Update dependencies
+
+## Options
+
+- Add `force` to expand all regardless of complexity
+- Add `research` for enhanced AI analysis
+
+## Results
+
+After bulk expansion:
+- Summary of tasks expanded
+- New subtask count
+- Updated complexity metrics
+- Suggested task order
