How do I avoid context window pollution when using this skill?

The skill is designed to use helper scripts as 'black boxes.' Instead of reading the full source code, you interact with them via CLI commands and --help flags to keep your context window clean.

Does this skill support multi-server setups?

Yes, the included with_server.py script can manage multiple servers simultaneously, such as a separate frontend and backend, ensuring they are ready before tests run.

Can it handle dynamic JavaScript applications?

Yes, the skill enforces a best practice of waiting for the 'networkidle' state to ensure all dynamic JavaScript content is fully rendered before inspection.

What browser does this skill use for testing?

It is optimized for Playwright's Chromium driver, running in headless mode for fast and reliable automation within your development environment.
