> Claude Code, Codex CLI etc can effectively do anything that a human could do by typing commands into a computer.

They still don't have good integration with the web browser, if you are debugging frontend you need to carry screenshots manually, it cannot inspect the DOM, run snippets of code in the console, etc.



You can tell them to take screenshots using Playwright and they will. They can also use Playwright to inspect the console and manipulate the DOM.

I've seen Codex CLI install Playwright Python when I asked it to do this and it found it wasn't yet available in the environment.


True. Although worth mentioning that there is tooling and (e.g. Playwright) MCPs around this. But definitely not integrated well enough!


I'd recommend the chrome-devtools-mcp for that: https://github.com/ChromeDevTools/chrome-devtools-mcp/

It's pretty new, but so far it's been a lifesaver.
