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:

npm install    # Install dependencies
npm link       # Create global 'browser' command

Commands

All commands work identically in both modes:

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

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

Always navigate first before interacting
View screenshots after each command to verify
Be specific in action descriptions
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
