How does this manage AI context window limits?

It utilizes 'black-box' helper scripts that Claude calls directly via the CLI, preventing large automation scripts from cluttering and exhausting the context window.

Can I see what the browser is doing during a test?

Yes, the skill is designed to take screenshots and capture console logs, allowing you to visually inspect the application state at any point.

Does this skill support multi-server setups?

Yes, the included with_server.py script allows you to manage both frontend and backend servers simultaneously for full-stack testing.

How does this skill handle dynamic web applications?

It uses a reconnaissance-then-action pattern, specifically waiting for network idle states before inspecting the DOM to ensure all JavaScript elements are rendered.
