      const files = result.pullResult?.files || [];
      const text = [
        `**Pull Complete**`,
        `- Status: ${result.statusCode}`,
        result.pullResult?.branch ? `- Branch: ${result.pullResult.branch}` : '',
        files.length ? `- Files Updated:\n${files.map(f => `  - ${f}`).join('\n')}` : '- No files changed'
      ].filter(Boolean).join('\n');
      
      return {
