Does it support deep site crawling?

Yes, it features a depth management system that can handle everything from single-page audits (depth 1) to deep recursive crawls (depth 3+).

How does it measure website performance?

It uses browser evaluation scripts to measure Core Web Vitals such as Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).

Can it check for accessibility violations?

Yes, it includes a WCAG 2.1 Level AA checklist to identify issues with color contrast, keyboard navigation, alt text, and ARIA labels.

How are testing results reported?

Findings are categorized by severity (Critical, Warning, Info) and include actionable details like reproduction steps, selectors, and user impact.

What browser tools does this skill use?

This skill primarily utilizes Playwright MCP tools to interact with, inspect, and automate browser actions within web applications for autonomous testing.

安全与测试

Automates comprehensive web application testing including functional validation, WCAG accessibility compliance, and Core Web Vitals performance analysis.

This skill empowers Claude to perform autonomous, systematic exploratory testing of web applications using Playwright MCP tools. It provides a structured framework for identifying functional bugs, detecting JavaScript console errors, auditing accessibility standards (WCAG 2.1 AA), measuring performance metrics like LCP and CLS, and spotting visual regressions. By following a prioritized methodology—focusing on critical user flows like authentication and payments—it ensures thorough coverage while managing testing depth and generating actionable, severity-categorized reports for developers.
