Agent Browser Automation is a powerful skill for Claude Code that enables sophisticated interaction with web pages through a CLI-driven browser engine. It provides a unique 'snapshot and ref' system that allows Claude to accurately identify and interact with elements using accessibility-tree-based references. Beyond simple navigation, it supports complex workflows including form filling, multi-session management, network request interception, and media capture via screenshots, PDFs, and video recording. It is an essential tool for developers building automated tests, web scrapers, or AI-driven web agents.
