How does this skill handle local servers?

It uses a bundled with_server.py script to manage the lifecycle of one or more local servers (e.g., frontend and backend) simultaneously while running automation scripts.

Why use native Playwright scripts instead of reading HTML?

Playwright allows for interaction with the actual rendered state of a web app, making it far more effective than static analysis for modern, dynamic web applications.

Does it support visual debugging?

Absolutely. The skill is designed to capture browser screenshots and console logs, which helps Claude identify and fix layout issues or script errors.

Can I test dynamic JavaScript applications?

Yes, the skill includes specific workflows like waiting for 'networkidle' to ensure dynamic content and JS are fully rendered before attempting to interact with elements.
