What the skill teaches

A web performance audit skill published in Cloudflare's skills repository. It has the agent record a performance trace of a page, analyse Core Web Vitals such as LCP and CLS, look through network requests for render-blocking resources and long request chains, take an accessibility snapshot, and then inspect the project's code for bundle size, unused JavaScript and CSS, polyfills and compression. It relies on browser and performance tools such as the Chrome DevTools MCP server, whose setup it shows, and asks for findings with measured impact. Nothing in it is specific to Cloudflare products.

Capabilities

  • Record a performance trace and read Core Web Vitals
  • Find render-blocking resources and request chains
  • Check bundles for unused code and polyfills
  • Report fixes with estimated time savings
