Browser Automation Skill

A skill for seamlessly enabling Claude Code to interface with a browser using Stagehand (AI browser automation framework). Because Stagehand accepts natural language instructions, it's significantly more context-efficient than native Playwright while providing more features built for automation.

Installation

On Claude Code, to add the marketplace, simply run:

/plugin marketplace add browserbase/agent-browse

Then install the plugin:

/plugin install browser-automation@browser-tools

If you prefer the manual interface:

1. On Claude Code, type /plugin
2. Select option 3. Add marketplace
3. Enter the marketplace source: browserbase/agent-browse
4. Press enter to select the browser-automation plugin
5. Hit enter again to Install now
6. Restart Claude Code for changes to take effect

Setup

Set your Anthropic API key:

export ANTHROPIC_API_KEY="your-api-key"

Usage

Once installed, just ask Claude to browse:

• "Go to Hacker News, get the top post comments, and summarize them "
• "QA test http://localhost:3000 and fix any bugs you encounter"
• "Order me a pizza, you're already signed in on Doordash"

Claude will handle the rest.
