+Set a task's status to pending.
+
+Arguments: $ARGUMENTS (task ID)
+
+## Setting Task to Pending
+
+This moves a task back to the pending state, useful for:
+- Resetting erroneously started tasks
+- Deferring work that was prematurely begun
+- Reorganizing sprint priorities
+
+## Execution
+
+```bash
+task-master set-status --id=$ARGUMENTS --status=pending
+```
+
+## Validation
+
+Before setting to pending:
+- Warn if task is currently in-progress
+- Check if this will block other tasks
+- Suggest documenting why it's being reset
+- Preserve any work already done
+
+## Smart Actions
+
+After setting to pending:
+- Update sprint planning if needed
+- Notify about freed resources
+- Suggest priority reassessment
+- Log the status change with context
