Can it handle dynamic JavaScript-heavy applications?

Absolutely. It utilizes Playwright and emphasizes waiting for 'networkidle' states to ensure dynamic content is fully rendered before any interactions occur.

How does the skill help with finding CSS selectors?

It follows a 'Reconnaissance-Then-Action' pattern where it first inspects the rendered DOM and takes screenshots to identify valid selectors before attempting to execute actions.

Does this skill support multi-server setups?

Yes, the included server helper script can manage multiple concurrent processes, such as a separate Python backend and a Node.js frontend, during a single test run.

Do I need to write complex server boilerplate for every test?

No, the skill provides a 'with_server.py' helper that handles server startup and teardown, allowing you to focus strictly on your Playwright automation logic.

Does it support headless mode?

Yes, the recommended pattern is to launch Chromium in headless mode for efficient, background execution within the terminal environment.
