Show HN: Get your coding agent off ~2019 JavaScript, onto modern web primitives

Google Chrome released a 1.0 agent skill with 200+ curated guides helping coding agents adopt modern web platform primitives instead of outdated JavaScript patterns. The tool includes a legacy-scan trained on 30k GitHub repos and achieved a jump from 55% to 92% task pass rates across Codex, Claude, and Agy benchmarks.

Background

Chrome has been investing in improving how AI coding agents write front-end code, partnering with Firefox, MDN, and Edge to standardize modern web guidance. This follows growing concerns that LLM-generated code often relies on deprecated or overly complex JavaScript patterns.
