What it does
A ranked list of fixes that make your slow site faster, starting with the ones that gain the most. It is grounded in one idea: delay, not bandwidth, is what slows most pages. You give the site and what feels slow. The skill looks at the path a request takes: DNS lookup, connection, secure handshake, then the data. It checks protocol versions, caching, compression and the order resources load in. It looks at what blocks the first paint, image size, fonts and scripts. It then checks eight items and scores them, weighted toward real-user measures like load time and layout shifts. Each fix comes with the reason it helps.
