Reduce Render-Blocking and Unused CSS and JS with AI
Stop plugin stylesheets and scripts from loading on pages that never use them, one page or template at a time.
Prerequisites
A connected site, the Code Snippets plugin (the AI can install it), and a way to measure such as PageSpeed Insights.
On [my site], look at what stylesheets and scripts load on [page or template, for example: my About page]. Tell me which of them come from plugins that page does not actually use. Then write a Code Snippets entry that dequeues only those handles, and only on the pages where they are not needed, leaving them enqueued everywhere the plugin is actually used. Save the snippet inactive, show me the list of assets before and the list after, and wait for my approval before activating. Do not edit my theme files. Remind me to run PageSpeed Insights before and after so I can measure the effect myself.

Skip the copy-paste. Just ask your AI for the “Reduce Render-Blocking and Unused CSS and JS with AI” recipe, or describe the task, and WPVibe runs these steps on your own site.
Open any page on a typical WordPress site and the browser downloads stylesheets and scripts from plugins that page never uses. A store plugin loads its cart and checkout CSS on your About page. A forms plugin loads on every post even though the form lives on one. Each extra file is another request the browser has to fetch and parse before it can finish drawing the page, and none of it does anything on the page it loaded on.
WPVibe finds which plugin assets are loading where they are not needed, then writes a small snippet that dequeues them on those pages while leaving them in place where they belong. On a test site we watched a plain page drop from ten WooCommerce files down to one, while the shop page kept all of its assets intact. The AI builds this as a Code Snippets entry, not a theme edit, so you can switch it off in one click if anything looks wrong. It never touches the pages that actually use the plugin.
Paste the prompt and name the page or template you want lightened. The AI lists the assets loading there, proposes exactly which handles to drop and on which conditions, and shows you the before and after so you can confirm the right files went away. This changes what loads, not how fast your site scores, so run PageSpeed Insights yourself before and after to see the effect on your own pages. Some block-based stylesheets load through WordPress core’s block system and need their own toggle, which the AI will call out rather than pretend it removed them.
Outcome
A conditional snippet dequeues the named plugin's unused assets on the pages you chose, while the pages that need them keep loading everything.
