Plugin function not pulling data

I am currently working on a plugin. As such, I inserted a block of code in the header with a function. The code is supposed to be pulling data from custom fields but it returns empty tag. However, it works if I add it directly to the header. Any ideas what the problem is? My code looks like below. 

<?php 
function pyramid() {
  ?>
<meta name="description" content="<?php $desc = get_post_meta($post->ID, 'description', true); if($desc) { echo $desc; } else { 

    // do nothing; 

} ?>" />
<?php
}; 
add_action( 'wp_head', 'pyramid' );

?>

It returns the result below when added through the plugin.

<meta name=description content>

global $post; needs to be added to the pyramid function.

Alternatively you can also use get_the_ID() instead of $post->ID

Also, if you wanted to, you can shorten your pyramid function to just

function pyramid() {
    global $post;
    ?><meta name="description" content="<?= get_post_meta($post->ID, 'description', true) ?: '' ?>" /> <?php
}; 
add_action( 'wp_head', 'pyramid' );
