What it does

The task

Open each URL in this list: urls. View each page at widths of 360, 390, 768, 1024 and 1440 pixels. Look for text or images that overflow, sideways scrolling, elements that overlap, tap targets smaller than 24 by 24 pixels and menus that do not open. Take a screenshot of each problem. Write a list in a new Google Doc with the URL, the width, the element and the problem, the worst first.

  • It works in any website and Google Docs, in the workspace you pick, and signs in with passwords from your Cuiar vault.
  • It runs once, when you start it.

Run it from your AI agent

Claude Code, Codex, Cursor and other MCP clients reach Cuiar at https://mcp.cuiar.com/mcp. Add the server one time, then ask for the task in plain words, or call run_task yourself.

1. Add Cuiar to Claude Code

claude mcp add --transport http cuiar https://mcp.cuiar.com/mcp

2. Ask your agent

Use the Cuiar tool run_task to run my "Check your pages at phone, tablet and desktop sizes" template with urls = https://brightleaf.app/, https://brightleaf.app/pricing, https://brightleaf.app/signup.

Setup for other agents: AI agents.
