Coding-agent skill set stewarded by major browser vendors, injecting web best practices and compatibility data.
Chrome has released Modern Web Guidance 1.0, a stable skill set that injects expert-reviewed web platform best practices and cross-browser compatibility data directly into coding agents. Version 1.0 adds a modernization workflow that scans existing codebases, an expanded guidance database, a public evaluation dashboard, and expands into a cross-browser initiative with Firefox and Edge.
Google Chrome, Microsoft Edge, Mozilla Firefox and MDN have jointly released Modern Web Guidance, a skill set that embeds web platform best practices and browser compatibility data directly into coding agents to steer them away from legacy JavaScript patterns. It ships with an npx install wizard and a legacy-scan detector trained on 30k GitHub repos to flag outdated patterns for modernization.
