SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables agents to control a headless browser via the Claude Code plugin for research, UI testing, and interacting with dynamic web applications. It extends capabilities beyond static data fetching by handling JS-rendered pages, DOM interactions, and visual capture.

Core Features & Use Cases

  • Navigation & Interaction: go to URLs, click elements, type into fields, capture screenshots, and extract page content.
  • UI Testing & Verification: validate UI states, run interaction sequences, and report results.
  • Use Case: Research a live product page, validate a checkout flow, or automate repetitive data collection from web apps.

Quick Start

Install and enable the Claude Code dev-browser plugin, then prompt with natural-language tasks such as: "Go to https://example.com and capture a screenshot," or "Navigate to the login page and verify the presence of the password field."

FAQPage Schema
How do I automate browser interactions and data extraction from JavaScript-heavy websites?▼

Browser automation enables you to navigate dynamic web pages, interact with elements, and extract content programmatically. This Skill controls a headless browser to handle SPAs and JS-rendered sites that static fetching cannot access, supporting click, type, navigation, and screenshot capture.

Can I use headless browser automation for UI testing and validation workflows?▼

Yes. This Skill automates UI testing by executing interaction sequences—navigation, clicking, typing, form submission—and capturing visual or DOM state to verify application behavior, validate workflows, and report test results.

What's the best way to test a dynamic checkout flow or multi-step web application?▼

Use browser automation to navigate through each step, interact with form fields and buttons, and validate state changes. This Skill captures screenshots and extracts page content to verify each stage of the workflow without manual intervention.

Does headless browser automation work with single-page applications and dynamic content?▼

Yes. This Skill is designed for SPAs and JavaScript-heavy pages that render content dynamically. It waits for and interacts with rendered DOM elements, making it suitable for modern web apps where static HTTP requests are insufficient.

How do I capture screenshots and extract structured data from live web pages?▼

Browser automation lets you navigate to a page, interact as needed, then capture visual snapshots or evaluate and extract DOM content. This Skill provides screenshot and content extraction for both visual verification and data collection tasks.

Can I automate research and data collection from websites I don't control?▼

Yes. This Skill automates repetitive navigation, interaction, and data extraction from external web applications. It handles dynamic page rendering and multi-step workflows to gather information without manual browsing.
