How do I see what the browser is doing in headless mode?

You can use the built-in screenshot capabilities to capture the rendered state of the application at any point during script execution to debug visual issues.

Does it support dynamic content and SPAs?

Absolutely. It utilizes a Reconnaissance-Then-Action pattern, encouraging the use of networkidle waits to ensure dynamic JavaScript content is fully rendered.

Do I need to read the helper script source code?

No, the scripts are designed as black boxes to save context window space. You can simply run them with the --help flag to see all available options.

What makes this skill better than writing manual Playwright scripts?

It includes specialized helper scripts like with_server.py that manage server lifecycles automatically, preventing common port conflicts and ensuring the environment is ready before tests run.

Can I test multiple servers at once?

Yes, the skill supports launching multiple servers, such as a Python backend and a React frontend, simultaneously before executing your automation scripts.
