    "description": "Control a JavaScript-enabled browser: navigate, inspect pages, fill forms, click controls, manage tabs, take screenshots, and reuse saved profiles. POST JSON with a bearer API key from admin@promptbox.cn. Set mode=agent for guided control IDs; omit it for low-level locators. Use current page IDs and a unique request_id for each state-changing action. Operations have a 45-second deadline; expired agent operations close their sessions. Inspect uncertain results before retrying. Human-verification pages require human help. See browser.md for actions, limits, and recovery. Version 2.3.1 bounds browser CPU and raster thread pools and corrects automatic startup under web-worker virtual-memory limits. The helper allows up to 110 hosting threads within the verified 120-thread account allowance, preserves ten slots for other work, and reserves capacity before opening pages. Resource-intensive pages may still close sessions; inspect uncertain results before recovery.",
