browser_get_outer_html
Debug browser rendering failures by retrieving raw outerHTML of a DOM element or the full document root. Use when semantic analysis returns empty to diagnose page rendering issues.
Instructions
DEBUG FALLBACK. Get the raw outerHTML of a DOM element by backendNodeId, or the entire document root if no ID is specified. Use this when get_semantic_surface returns an empty tree — it helps diagnose whether the page actually rendered.\n\nWARNING: Raw HTML is token-expensive. Always prefer get_semantic_surface for page understanding. Use this tool ONLY for debugging perception failures.\n\nThe output is truncated to maxLength characters (default: 5000) to protect your context window.
