Modern Web Guidance is an agent skill and CLI tool designed to help AI coding agents build web applications using modern, secure, and high-performance APIs rather than outdated workarounds. Supported by the Google Chrome team, it injects expert-curated web platform best practices directly into an agent's context window to prevent the generation of bloated, legacy code.

Example prompts

  • “Audit this project for modern web best practices and modernization opportunities”
  • “What is the recommended modern way to implement responsive dialogs and popovers?”
