Browser Automation

Automates Chrome browser interactions using the DevTools Protocol for web scraping, site exploration, and interactive element selection.

About

This skill provides a minimal yet powerful set of Chrome DevTools Protocol (CDP) tools designed for seamless browser automation and data extraction within the Claude environment. It allows users to launch Chrome instances (with optional profile support for authenticated sessions), navigate tabs, execute custom JavaScript expressions in real-time, capture screenshots, and utilize a unique interactive DOM element picker. It is ideal for developers needing to bridge the gap between AI-driven code generation and live web environments for scraping, testing, or visual verification.
