node -e "
fetch('http://localhost:3100/api/wechat/send-file', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'Authorization': 'Bearer $TEAMMCP_KEY' },
  body: JSON.stringify({ file_path: '$ARGUMENTS' })
}).then(r=>r.json()).then(d => {
  if (d.ok) console.log('Image sent:', d.fileName, '(' + d.size + ' bytes)');
  else console.error('Failed:', d.error);
});
