assistantDisplayText function

String assistantDisplayText(List<ContentBlock> content)

Row label for a message with no visible text or reasoning.

Ported from TS summarizeAssistantActivity: tool-call-only rows label themselves, then image-only rows; text/thinking content labels nothing (the preview carries it).

Implementation

String assistantDisplayText(List<ContentBlock> content) {
  if (textOfBlocks(content).isNotEmpty ||
      thinkingOfBlocks(content).isNotEmpty) {
    return '';
  }
  final tools = content.whereType<ToolCall>().toList();
  if (tools.isNotEmpty) return 'Tool call only';
  final images = content.whereType<ImageContent>().length;
  if (images > 0) return 'Images ×$images';
  return '';
}
