Playwright Cli

You get the full automation toolkit: clicking elements by reference IDs from snapshots, filling forms, managing tabs, mocking network requests, and even recording videos with annotated actions. The state management commands are especially practical for debugging auth flows, since you can save and restore cookies, localStorage, and full browser state. The snapshot system is clever, it generates YAML representations of the page after each action so Claude can see what changed and pick the right element references. If you're doing any browser testing or scraping work with Claude, the raw output mode makes it easy to pipe results into jq or other tools.
