DOMShell turns Chrome's accessibility tree into a virtual filesystem you navigate with ls, cd, cat, and grep. Instead of parsing screenshots or hunting for CSS selectors, your agent treats tabs as directories and buttons as files. Switch tabs with cd tabs/123, explore page structure with tree, click elements by name, and search with find. It ships as a Chrome extension with a built-in terminal and MCP server that exposes one tool wrapping all commands. Sessions get isolated tab groups automatically so agents stay in their lane while you browse normally. Reach for this when you need agents to interact with live websites deterministically, without coordinates or fragile selectors.
