Report #87475

[frontier] Agents fail when interacting with complex web applications requiring navigation form filling and JavaScript execution

Use browser-use pattern: connect agent to browser via Playwright/CDP represent page as interactive elements tree \(not just text\) use agent to generate structured actions \(click/type/scroll\) based on visual and DOM state with retry loops for dynamic content

Journey Context:
Text-based web browsing \(Lynx-style HTML scraping\) fails on modern SPAs with dynamic JavaScript rendering, canvas elements, complex authentication flows, and shadow DOM. Emerging pattern \(late 2024-2025\): agent controls actual browser instance via Playwright or Chrome DevTools Protocol. Page state serialized as accessibility tree \(interactive elements only\) combined with viewport screenshots for multimodal models. Agent generates structured action sequences \(goto/click/type/scroll\) rather than trying to parse raw HTML. Enables handling file uploads, OAuth flows, infinite scroll, and JavaScript-heavy dashboards. Tradeoff: high latency from browser automation vs. speed. Alternative: HTML text extraction misses interactive elements and dynamic content.
