How does Web CLI differ from standard WebFetch tools?

Web CLI renders JavaScript and handles dynamic content like React, Vue, or Phoenix LiveView, whereas standard fetch tools usually only retrieve static HTML.

Can I see what the browser sees during automation?

Yes, you can use the --screenshot flag to save a visual representation of the page to a file for visual verification and debugging.

Can I test login-protected pages using this skill?

Yes, Web CLI supports session persistence and named profiles, allowing you to log in to a site and perform subsequent actions within the same authenticated session.

Is it possible to run custom scripts on the page?

Yes, the --js option allows you to execute arbitrary JavaScript after the page loads, which is perfect for clicking buttons or triggering specific UI events.

Does it work with local development servers?

Absolutely. It is specifically designed to interact with localhost environments to verify features and build status as you develop.
