WooCommerce Meta Description

You mean to use (long) description instead of the short description, right? You can do that with a code snippet which you can place in your functions.php file.

add_filter(
	'the_seo_framework_fetched_description_excerpt',
	function( $excerpt, $d, $args ) {

		$tsf = tsf();

		if ( null === $args ) {
			// In the loop.
			$is_product = $tsf->is_product();
		} else {
			// Out the loop, admin etc.
			$is_product = ! $args['taxonomy'] && ! $args['pta'] && $tsf->is_product( $args['id'] );
		}

		if ( $is_product ?? false ) {
			$product    = get_post( $args['id'] ?? $tsf->get_the_real_ID() );
			$product_id = $product->ID;

			// Don't leak protected content.
			if ( $tsf->is_protected( $product_id ) ) return $excerpt;

			$old_excerpt = $excerpt;
			$excerpt     = $tsf->uses_non_html_page_builder( $product_id ) ? '' : $product->post_content;

			if ( $excerpt ) {
				// Apply half of TSF's description AI here: selectively strip content and HTML.
				$excerpt = $tsf->s_excerpt_raw(
					$tsf->strip_paragraph_urls( $tsf->strip_newline_urls( $excerpt ) )
				);
			}
			$excerpt = $excerpt ?: $old_excerpt;
		}

		return $excerpt;
	},
	10,
	3
);

Thanks, Johnny!

The filter above will output deprecation notices from TSF v5.0.
Here’s the updated version:

add_filter(
	'the_seo_framework_description_excerpt',
	function( $excerpt, $args ) {

		$tsf = tsf();

		if ( null === $args ) {
			// In the loop.
			$is_product = $tsf->query()->is_product();
		} else {
			// Out the loop, admin etc.
			$is_product = ! $args['taxonomy'] && ! $args['pta'] && $tsf->query()->is_product( $args['id'] );
		}

		if ( $is_product ?? false ) {
			$product    = get_post( $args['id'] ?? $tsf->query()->get_the_real_id() );
			$product_id = $product->ID;

			$tsfpostdata = $tsf->data()->post();

			// Don't leak protected content.
			if ( $tsfpostdata->is_protected( $product_id ) )
				return $excerpt;

			$old_excerpt = $excerpt;
			$excerpt     = $tsfpostdata->uses_non_html_page_builder( $product_id ) ? '' : $product->post_content;

			if ( $excerpt ) {
				$tsfhtml = $tsf->format()->html();
				// Apply half of TSF's description AI here: selectively strip content and HTML.
				$excerpt = $tsfhtml->extract_content( $tsfhtml->strip_paragraph_urls( $tsfhtml->strip_newline_urls(
					$excerpt
				) ) );
			}
			$excerpt = $excerpt ?: $old_excerpt;
		}

		return $excerpt;
	},
	10,
	3
);
