SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Use agent-browser for cases where plain HTTP fetch is not enough to render and interact with JS-heavy pages, enabling live DOM inspection and debugging.

Core Features & Use Cases

JS-rendered pages, interactive browser debugging, and DOM inspection
Screenshots and state captures for complex web flows, including private SaaS or gated content
Use Case: Open a page, wait for network idle, snapshot the DOM, and extract data or verify UI steps in automated sessions.

Quick Start

Launch the agent-browser CLI against a URL to render the page and inspect live DOM state.

Frequently Asked Questions about agent-browser

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I automate browser tasks and debug JavaScript-rendered pages?▼

To automate browser tasks and debug JavaScript-rendered pages, launch the agent-browser CLI against a URL to render the page, wait for network idle, and inspect the live DOM state. This enables scripted interactions and screenshots for complex web flows.

When do I need a headless browser instead of a plain HTTP fetch?▼

You need a headless browser instead of a plain HTTP fetch when targeting JavaScript-heavy pages that require client-side rendering. It enables live DOM inspection and browser automation for dynamic web apps and private SaaS dashboards where raw HTML fetching fails.

How do I extract data from private SaaS dashboards requiring authentication?▼

To extract data from private SaaS dashboards, use agent-browser to automate browser interactions, wait for network idle, and snapshot the DOM. This allows you to verify UI steps and capture state behind gated content during automated sessions.

Do I need a local Chromium runtime to inspect live DOM state?▼

Yes, you need a local Chromium runtime and the agent-browser CLI to inspect live DOM state. The runtime handles rendering JavaScript-heavy pages, while the CLI provides the automation interface and runtime hints referenced in its documentation.

What is the best way to capture screenshots of dynamic web app flows?▼

The best way to capture screenshots of dynamic web app flows is using a headless browser automation tool like agent-browser. It renders JS-heavy pages, waits for network idle, and captures visual state and DOM snapshots for automated verification.

Why does my HTTP fetch return empty content for JavaScript-heavy pages?▼

HTTP fetch returns empty content for JavaScript-heavy pages because it cannot execute client-side scripts. You must use a headless browser to render the page, wait for network idle, and inspect the fully rendered live DOM to extract data accurately.
