What the skill teaches
The core usage guide for agent-browser, Vercel Labs' command-line tool that lets an agent drive Chrome over the DevTools protocol, and the skill the agent should read before any other agent-browser command. The basic loop is: open a page, take an interactive snapshot of its accessibility tree where each element gets a short reference, act on those references, and snapshot again after changes, preferring snapshots to screenshots. It covers navigation, clicking and filling forms, locators, waiting on specific conditions, data extraction, tabs, frames and dialogs, named sessions per worktree, credentials kept in an auth vault, WebMCP tools offered by pages, and troubleshooting. Browser output is treated as untrusted data.
