SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires bun, and includes references (resource) components.

What problem does it solve? Developers using AI coding assistants cannot see what the AI is doing in the browser, making web testing and automation opaque. This Skill launches a visible, AI-controlled Chromium window where every action appears in real time, with a sidebar extension showing a live activity feed and chat. ## Core Features & Use Cases - Visible AI-Controlled Browser: Launches a headed Chromium instance (separate from your regular Chrome) that you can watch as the AI navigates, clicks, and fills forms. - Sidebar Extension with Live Feed: Auto-loads a side panel showing every command the AI executes in real time, plus a chat tab where a sidebar agent executes natural-language browser tasks. - Anti-Bot Stealth: Built-in stealth patches let sites like Google and news sites load without captcha challenges. - Use Case: Run a QA skill and watch every page load, click, and assertion happen in the visible browser window instead of trusting a headless log. ## Quick Start Ask the AI to open the gstack browser so you can watch it control a real Chromium window with the sidebar feed.

FAQPage Schema
How do I launch an AI-controlled browser with Claude?▼

Invoke the open-gstack-browser skill, which runs a setup check, cleans up stale browse servers, then connects a headed Chromium instance on port 34567. The sidebar extension auto-loads so you can watch every action in real time.

How do I watch AI browser automation in real time?▼

The skill launches a visible Chromium window with a sidebar extension showing a live activity feed. Every goto, click, fill, and snapshot command the AI runs appears in the feed as it happens.

Does the gstack browser affect my regular Chrome installation?▼

No. It launches a separate Playwright-controlled Chromium instance with its own profile directory, leaving your regular Chrome and its sessions untouched.

Why is the gstack sidebar extension not showing up in the browser?▼

The extension is loaded at launch time but may not appear immediately. Check chrome://extensions for gstack browse, pin it via the puzzle piece icon, or load it manually from the extension path printed during setup.

What port does the gstack browser extension use?▼

The browser always uses port 34567 so the sidebar extension can auto-connect. If the badge stays gray, click the gstack icon and enter port 34567 manually.
