Does it support authenticated sessions or logins?

Yes, Agent Browser allows you to save and load authentication states and manage named sessions to persist cookies and local storage across different tasks.

Can I use Agent Browser for automated end-to-end testing?

Yes, it is specifically designed for writing bash-based e2e tests, allowing you to simulate user behavior, check visibility, and verify UI states.

How do I see what the browser is doing during a task?

You can use the screenshot command to capture the current view, or use the trace and console commands to debug page errors and network activity.

What makes Agent Browser better for AI than standard selectors?

It uses accessibility snapshots to provide deterministic element refs (@e1, @e2), which are much more reliable for LLMs to process than fragile, frequently changing CSS or XPath selectors.

How do I install the necessary browser drivers?

The skill includes a built-in 'install' command that automatically downloads Chromium and handles system dependencies for you.

Automates browser interactions and UI testing using AI-friendly accessibility snapshots and deterministic element references.

Agent Browser is a specialized headless browser CLI designed specifically for AI agents, replacing fragile CSS selectors with a robust 'snapshot-then-act' workflow. By generating accessibility snapshots with unique refs (e.g., @e2), it allows Claude to identify and interact with UI elements with high precision, making it ideal for troubleshooting visual bugs, performing end-to-end testing, and automating complex multi-step web workflows without the reliability issues of traditional DOM selectors.
