Gives agents structured access to web pages through headless Chromium without dumping entire accessibility trees on every call. Navigate, observe with three detail levels, find elements spatially or semantically, interact with clicks and typing, manage tabs, monitor console output and network requests, take screenshots. The default navigate returns 336 characters for Hacker News versus 61,000+ in comparable tools. Ships with tool profiles to control which of 43 operations load at startup: core (7 tools), browse (23), full set, or specialized modes for development and auditing. Agents can activate additional tool groups mid-session. Designed to cut token costs on production browsing workloads by letting agents request only the page structure they need.
