Can this skill manage multiple servers at once?

Yes, the included helper scripts support managing multiple server lifecycles, such as running a backend API and a frontend dev server simultaneously for full integration testing.

Does it support testing static HTML files?

Absolutely. The skill can identify selectors by reading HTML files directly or automate them using Playwright via local file URLs.

How does it handle dynamic, JavaScript-heavy websites?

It implements a 'networkidle' wait state strategy to ensure all JavaScript has executed and the DOM is fully rendered before performing reconnaissance or actions.

Are the testing scripts executed in a visible browser window?

By default, the skill utilizes Chromium in headless mode to perform background automation efficiently without interrupting your workflow.
