Does it support debugging pages that require a login?

Yes, by using the --profile flag during browser startup, you can preserve user profiles and session data to debug authenticated sections of your application.

Why use this instead of a standard MCP browser server?

This skill is designed to be significantly more token-efficient, consuming only about 300 tokens compared to the 13k-18k tokens typically required by standard Model Context Protocol browser servers.

Can I test Safari-specific layout issues?

Yes, the toolkit includes WebKit support via Playwright, allowing you to simulate Safari's rendering engine to catch platform-specific CSS bugs.

How does Claude use this to automatically fix my website?

Claude enters a self-debugging loop: it makes a code change, runs a screenshot or console check to verify the result, and iterates until the visual or functional issue is resolved.

Automatización de Navegadores

Debugs frontend code, captures screenshots, and inspects DOM elements using a token-efficient browser automation framework.

Acerca de

The Website Debug skill is a lightweight, agent-focused toolkit designed to bridge the gap between AI-generated code and visual reality. By leveraging the Chrome DevTools Protocol and Playwright, it enables Claude to perform real-time visual verification, capture console logs, and test responsive designs without the heavy context overhead of traditional MCP servers. This skill is essential for developers looking to automate the "write-test-fix" loop for CSS, HTML, and JavaScript, providing precise element selection and cross-browser testing capabilities for both Chrome and WebKit engines.
