What is the recommended way to handle dynamic content?

The skill utilizes a 'Reconnaissance-Then-Action' pattern, which prioritizes waiting for 'networkidle' before inspecting the DOM to ensure all JS components are loaded.

Does it work with static HTML files?

Yes, the decision tree includes a specific path for static HTML that identifies selectors directly from the file before executing Playwright scripts.

How does this prevent context window pollution?

It provides pre-built helper scripts designed to be used as black boxes via command-line arguments rather than being read into the context window as source code.

Can I capture visual output from the tests?

Yes, the skill provides specific patterns for capturing full-page screenshots to assist in visual debugging and UI verification.

Does this skill support multi-server setups?

Yes, the included with_server.py helper allows you to manage multiple servers simultaneously, such as a separate backend and frontend.
