SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audit and fix mobile responsiveness across every page of a project, using Chrome MCP screenshots at two breakpoints (375px mobile, 1440px desktop). Design-aware: reads existing design docs to preserve aesthetic intent, not just "make it fit." Use when asked to "make it responsive", "fix mobile", "responsive audit", or after building a desktop-first UI that needs mobile adaptation.

Core Features & Use Cases

  • Systematically audit and fix every page for mobile responsiveness, with visual verification via browser screenshots at mobile and desktop widths.
  • Reads your design doc first to preserve aesthetic direction, not just fix layout.
  • Applies container queries for component-level adjustments and viewport queries for page-level layout changes.

When should I use a responsive audit for my web application?
