ALWAYS ACTIVE — Browser automation protocol. When a task means driving a REAL, JS-rendered browser — navigate to a page, click, fill a form on a live site, scrape a dynamic/SPA page, or screenshot a rendered UI — you MUST use the agent-browser CLI and its accessibility-tree snapshot (compact @eN refs) instead of fetching raw HTML or reasoning over screenshots. Triggers: browser, navigate, click, fill, submit a form, scrape a JS-rendered/SPA page, interact with a web app, screenshot a page.
