What it does

This skill gives an AI agent a checklist for one web performance topic: whether a website uses the newer HTTP/2 or HTTP/3 protocols to load files faster. When it is active, the agent checks the server, explains the benefits of these protocols in plain terms, and suggests enabling them in a web server like Nginx or Apache or through a CDN, while first confirming the real bottleneck with DevTools, Lighthouse, or field data.

Great for

  • Developers or site owners whose pages load slowly and who want to know if the protocol setup is part of the problem
  • Front-end teams running a performance review before a launch
  • People learning why HTTP/2 and HTTP/3 matter compared with HTTP/1.1

Skip it if

  • Sites that already serve HTTP/2 or HTTP/3 correctly, where the skill adds little beyond confirming it (the cause of slowness is likely elsewhere)
  • Users who need detailed, framework-specific configuration, since the main instructions point to a separate reference file that was not reviewed here for this assessment's summary
  • Making live server changes without review, because the skill only recommends changes and does not itself verify or deploy them

Try asking

  • “Check whether my site at example.com is served over HTTP/2 or HTTP/3 and tell me if that is slowing the page down.”
  • “Audit my Nginx config and explain how to enable HTTP/2 for my static assets.”
  • “Review why my page loads slowly and whether the protocol or the asset sizes are the real bottleneck.”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent a real URL or DevTools/Lighthouse output so it can verify the protocol instead of guessing.
  • Ask it to name the exact files or requests involved so recommendations stay specific.
  • Pair it with other performance skills, since HTTP protocol changes rarely fix problems caused by large images or scripts.
