+# Browser Automation Skill
+
+A skill for seamlessly enabling **[Claude Code](https://docs.claude.com/en/docs/claude-code/overview)** to interface with a browser using **[Stagehand](https://github.com/browserbase/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:
+
+```bash
+/plugin marketplace add browserbase/agent-browse
+```
+
+Then install the plugin:
+
+```bash
+/plugin install agent-browse@browserbase
+```
+
+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 `agent-browse` plugin
+5. Hit enter again to `Install now`
+6. **Restart Claude Code** for changes to take effect
+
+## Setup
+
+Set your Anthropic API key:
+```bash
+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.
+
+## Troubleshooting
+
+### Chrome not found
+
+Install Chrome for your platform:
+- **macOS** or **Windows**: https://www.google.com/chrome/
+- **Linux**: `sudo apt install google-chrome-stable`
+
+### Profile refresh
+
+To refresh cookies from your main Chrome profile:
+```bash
+rm -rf .chrome-profile
+```
