TESTING GOOGLE'S "MODERN-WEB-GUIDANCE" SKILL ON A REAL REACT APP

Summary from the TLDR Dev newsletter

Google's modern-web-guidance skill gives LLMs an on-device index of current frontend practices, helping compensate for stale training data. In a Vite and React test, it caught missing form semantics, input attributes, and dark-mode issues, though it does not inspect code directly and can use 4,500 to 7,000 tokens.
