Does this work in CI/CD environments?

Yes, this skill is specifically designed for headless execution, making it the preferred choice for automated CI/CD pipelines where a GUI is unavailable.

What is the 'Iron Law of Verification'?

It is a mandatory practice within this skill where every action (click, type, navigate) must be followed by a snapshot or wait condition to prove the UI state changed as expected.

Can I use this for debugging console messages?

No, Playwright MCP is designed for headless automation and does not support reading console logs or network requests. For interactive debugging, use the Chrome MCP skill.

Which browsers are supported by this skill?

Through Playwright MCP, this skill supports testing across Chromium, Firefox, and WebKit (Safari engine) for comprehensive cross-browser coverage.
