Automates browser workflows and web interactions with persistent page state for seamless multi-step tasks.
The Dev Browser skill equips Claude Code with a powerful Chromium-based automation engine, enabling it to navigate websites, fill forms, and extract structured data through a persistent session architecture. Unlike standard one-off scrapers, this skill maintains page state across multiple script executions, allowing for complex, stateful workflows like multi-page checkout testing or data mining behind authentication. It features advanced ARIA snapshotting for intelligent element discovery and supports both standalone Chromium instances and direct connections to existing Chrome browsers via Extension Mode.
