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

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

这个Skill的文档质量良好，内容组织清晰，示例丰富实用，涵盖了常见的使用场景。文档说明了本地Chrome和远程Browserbase两种模式各自的适用场景，并提供了清晰的命令接口说明。不足之处是缺少实际可运行的工具文件，只有文档说明；setup清单较长，初次配置需要较多步骤。整体来看文档本身质量不错，但作为CLI工具Skill，缺少核心代码文件是一大遗憾。
