Playwright meets accessibility trees for browser automation through Claude. You get 8 tools: navigate, click, type, scroll, snapshot, extract_content, go_back, and wait. The hook here is token efficiency for local LLMs. Instead of dumping full HTML to your context window, it sends accessibility trees with ref IDs like e1, e2 for stable element targeting, plus MarkGrab for clean markdown extraction. Claims 500 to 1,500 tokens per step versus 4,000 to 10,000 for browser-use. Built by the QuartzUnit folks who made MarkGrab, SnapGrab, and DocPick. Reach for this when you need Claude to navigate websites but don't want to burn tokens on raw DOM dumps or coordinate hunting.
