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)

7w4.net小蔥技能站收錄全網優質技能，值得收藏。

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

這個Skill的文件質量良好，內容組織清晰，示例豐富實用，涵蓋了常見的使用場景。文件說明了本地Chrome和遠端Browserbase兩種模式各自的適用場景，並提供了清晰的命令介面說明。不足之處是缺少實際可執行的工具檔案，只有文件說明；setup清單較長，初次配置需要較多步驟。整體來看文件本身質量不錯，但作為CLI工具Skill，缺少核心程式碼檔案是一大遺憾。
