SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Direct browser control via CDP to automate, test, and scrape on a real Chrome session without launching extra browsers.

Core Features & Use Cases

  • Attach to a running Chrome via the CDP harness and drive deterministic tasks with preloaded helpers.
  • Reuse local or cloud browser profiles to preserve login state for multi-agent scenarios.
  • Perform end-to-end browser automation including navigation, interaction, and verification with built-in utilities.

Quick Start

Attach to your running browser and begin issuing CDP commands with a single command: browser-harness --setup.

Frequently Asked Questions about browser-harness

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

FAQPage Schema
How do I automate a real Chrome session without spawning new browser instances?▼

You can attach to a live Chrome session through the Browser Harness CDP interface, enabling automation on a real browser without launching extra instances. This allows deterministic task execution via preloaded helpers.

Can I reuse existing browser profiles to preserve login state for web scraping?▼

Yes, browser automation via CDP supports reusing local or cloud browser profiles to preserve login state. This is particularly useful for multi-agent scenarios requiring authenticated sessions.

What is CDP and how does it work for end-to-end browser testing?▼

CDP, or Chrome DevTools Protocol, allows direct control of a running Chrome browser. The Browser Harness attaches to this live session to drive navigation, interaction, and verification tasks for end-to-end testing.

How do I set up browser-harness to start issuing CDP commands?▼

To set up the browser harness, attach to your running browser and begin issuing CDP commands using the single command: browser-harness --setup. This connects the harness to your active Chrome instance.

Does browser automation via CDP support multi-agent environments?▼

Yes, attaching to a running Chrome via the CDP harness supports multi-agent environments. It drives deterministic tasks with preloaded helpers and reuses profiles to maintain state across agents.

What are the limitations of attaching to an existing Chrome session for automation?▼

Attaching to an existing Chrome session requires a live browser running with CDP enabled. It focuses on deterministic tasks and profile reuse rather than spawning isolated, fresh browser instances for parallel testing.
