+# Browser Automation
+
+Automate browser interactions using Stagehand CLI with Claude.
+
+### First: Environment Selection (Local vs Remote)
+
+The skill automatically selects between local and remote browser environments:
+- **If Browserbase API keys exist** (BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID in .env file): Uses remote Browserbase environment
+- **If no Browserbase API keys**: Falls back to local Chrome browser
+- **No user prompting**: The selection happens automatically based on available configuration
+
+## Setup (First Time Only)
+
+Check `setup.json` in this directory. If `setupComplete: false`:
+
+```bash
+npm install    # Install dependencies
+npm link       # Create global 'browser' command
+```
+
+## Commands
+
+All commands work identically in both modes:
+
+```bash
+browser navigate <url>                    # Go to URL
+browser act "<action>"                    # Natural language action
+browser extract "<instruction>" ['{}']    # Extract data (optional schema)
+browser observe "<query>"                 # Discover elements
+browser screenshot                        # Take screenshot
+browser close                             # Close browser
+```
+
+## Quick Example
+
+```bash
+browser navigate https://example.com
+browser act "click the Sign In button"
+browser extract "get the page title"
+browser close
+```
+
+## Mode Comparison
+
+| Feature | Local | Browserbase |
+|---------|-------|-------------|
+| Speed | Faster | Slightly slower |
+| Setup | Chrome required | API key required |
+| Stealth mode | No | Yes |
+| Proxy/CAPTCHA | No | Yes |
+| Best for | Development | Production/scraping |
+
+## Best Practices
+
+1. **Always navigate first** before interacting
+2. **View screenshots** after each command to verify
+3. **Be specific** in action descriptions
+4. **Close browser** when done
+
+## Troubleshooting
+
+- **Chrome not found**: Install Chrome or use Browserbase mode
+- **Action fails**: Use `browser observe` to discover available elements
+- **Browserbase fails**: Verify API key and project ID are set
