Local

CommandLineExecutionEngine uses the local computer env to execute provided command line code. There are CommandLineTool and LocalScriptExecutionTool two implemented tools, that can be useful for Desktop Automation or Computer-Use Agents (such as File Management, Application Control). You can control your computer using natural language, something like:

  • set my mac output volume 50
  • list all running applications in my mac
  • tell a story and then read it out loud
  • tell a story about moon and save it into a text file
  • ...

Attention! It might be dangerous to execute the code in a production online serving environment. It needs to be executed through security sandbox environment if used in online serving.
