What is GenAIScript?

GenAIScript is a JavaScript toolbox for programmatically assembling prompts and orchestrating LLMs, tools, and data in code. It runs as a Visual Studio Code extension or a command-line tool and is designed for developers who want to treat prompt engineering like software engineering.

How to use GenAIScript?

Install the Visual Studio Code extension or use the command line (npx genaiscript). Write scripts using the $ template tag to create prompts and the def function to include files, data, or schemas.
