Modern Web Guidance teaches coding agents current browser practice
Modern Web Guidance 1.0 supplies coding agents with reviewed web-development skills and browser-compatibility data, plus a limited static scan for modernizing existing code.
Chrome’s November 10 stable release addresses a familiar weakness of generated websites: code can run while getting keyboard interaction, accessibility or browser behavior wrong.
Modern Web Guidance provides skills and use-case guidance that coding agents can retrieve while building. Firefox and Edge are joining the effort. [1]
Version 1.0 adds a modernization workflow for existing HTML, CSS, JavaScript and package files. Its first scan checks a limited set of static patterns; it is not a complete site audit. The guides also cover decisions such as native dialogs, focus management, reduced motion and performance, with browser-support information attached. [1]
For a founder building a publication or product with agents, this is worth a small trial now. Install it in a test branch, specify the browsers the product must support, and ask for one focused improvement—such as a dialog that works entirely by keyboard. Inspect the result on a phone and with assistive interaction. Better guidance should improve the finished experience, not merely produce a cleaner-looking diff.
