Google issued version 1.0 of Modern Web Guidance, which is a free skill set that web development teams may use as an enhancement to their AI coding tools, in order for those tools to write code based on current browser features. The skills are in the form of packaged guidelines that the agent will look at while writing the code. The code generated by the agent will also be sent to the same pages that are evaluated for metrics such as Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and accessibility.

Philip Walton, a senior staff developer relations engineer at Google, announced the release in a Chrome for Developers post. Version 1.0 adds an audit for existing code, and Firefox and Edge are joining the project. Chrome first released the guidance as an early preview at Google I/O in May.

Teams can install it by running npx modern-web-guidance@latest install in a project directory.…
