Stagehand Browser Automation Plugin

Browser automation skill for Claude Code using Stagehand. This plugin enables Claude to automate web browser interactions, extract data, and navigate websites using natural language.

Installation

Install the plugin from the Claude Code marketplace:

/plugin install stagehand@claude-plugin-directory

Prerequisites

This plugin requires the browser automation CLI tools to be installed separately. The CLI tools are available from the GitHub marketplace.

Step 1: Add the GitHub Marketplace

/plugin marketplace add browserbase/agent-browse

Step 2: Install the Browser Automation CLI Plugin

/plugin install browser-automation@browser-tools

Step 3: Set Up the CLI Tools

After installing the browser-automation plugin, you need to set up the CLI tools:

1. Navigate to the plugin directory (typically ~/.claude/plugins/browser-automation/)

2. Install dependencies and build:

   npm install
   

3. Link the browser command globally:

   npm link
   

4. Configure your Anthropic API key:

   export ANTHROPIC_API_KEY="your-api-key-here"
   

   Or use Claude Code's subscription token (recommended if you have Claude Pro/Max):

   claude setup-token
   

Step 4: Verify Installation

Test that the browser command is available:

browser navigate https://example.com

Usage

Once installed and configured, you can use natural language to automate browser tasks:

• "Go to Hacker News, get the top post comments, and summarize them"
• "QA test http://localhost:3000 and fix any bugs you encounter"
• "Extract product information from example.com/products"

Claude will automatically use the browser automation skill when you ask for web-related tasks.
