vannifr/cross-browser-render-check

Use when you need to check browser-specific CSS/layout/JS rendering differences (Chromium/Firefox/WebKit) before shipping a CSS/JS change or investigating compatibility issues across engines. NOT for viewport/breakpoint layout review (use responsive-visual-review), NOT for functional/interaction E2E testing across browsers (use playwright-testing), NOT for designing a polyfill/feature-detection fix.

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

The workflow checks cross-browser rendering using local project files, Playwright captures, and checking caniuse.com (which is reference documentation searched or checked by the agent), without ingesting outsider-submitted free text or continuous communication feeds.

Where we found it

caniuse.com

domain · 1 site

The skill instructs the agent to manually check caniuse.com as a reference for CSS feature support, but the plugin itself does not fetch or read from this domain at runtime.
