This is precisely how the Playwright MCP works, which lets something like Claude directly test a website.

I've mentioned several times and gotten snarky remarks about how rewriting your code so it fits in your head, and in the LLM's context helps the LLM code better, to which people complain about rewriting code just for an LLM, not realizing that the suggestion is to follow better coding principles to let the LLM code better, which has the net benefit of letting humans code better! Well looks like, if you support accessibility in your web apps correctly, Playwright MCP will work correctly for you.

Amazing.

Was looking for this comment. I'd like to see this approach in the comparison...having the LLM build a playwright script and use it. I suspect it would beat time-to-market for the api, and be close-ish in elapsed time per transaction.

Harder to scale if it's doing a lot of them, I suppose.

Using playwright-cli with Claude code is highly effective for debugging locally deployed web apps with essentially zero setup.
