GLM × Kane CLI: AI-Built Site Fails Core Web Vitals

In this video you'll learn how to test an AI-generated site for Core Web Vitals with Kane CLI, in plain English: extract LCP, FCP, TTFB, CLS and INP, assert thresholds, and get a root-cause report with a fix prompt when it fails. Kane CLI runs natural-language browser and API tests from your terminal and saves them to KaneAI, TestMu AI's AI-native test agent. In this video you will learn: • How GLM-5.2 turns a detailed design brief into a scroll-driven, GSAP-animated landing page (AURALIS) • How to write a Kane CLI test that pulls all five Core Web Vitals from the page and asserts LCP under 4000 ms and CLS under 0.1 • Why the test failed — a layout shift score of 0.99 against a 0.1 limit — and how Kane CLI explains it in plain language • How KaneAI's report tags the root cause, suggests a fix, and gives you a "Copy fix prompt" to paste straight back into your AI model • How a second Kane CLI test checks lazy-loaded images on scroll and passes, with every image request visible in the network evidence Demo: AURALIS audio-brand site built by GLM-5.2, tested by Kane CLI — 1 failed run (CLS), 1 passed run (lazy-load), both saved in KaneAI. #KaneCLI #CoreWebVitals #GLM #TestAutomation #TestMuAI Start Free Testing: https://www.testmuai.com/register/?utm_source=youtube&utm_medium=organic&utm_term=APq4i-hLr7w&utm_campaign=youtube_organic
