       $failed = false;
       foreach ($response->content as $block) {
           // This example declares only the browser toolset; route other tools here if you add them.
-          // Read toolset_name through array access: the SDK keeps it as raw data until a release types it.
-          if (!($block instanceof ToolUseBlock) || ($block['toolsetName'] ?? $block['toolset_name'] ?? null) !== 'browser') {

           $result = ['type' => 'tool_result', 'tool_use_id' => $block->id, 'toolset_name' => 'browser'];
