The Laminar Playground provides the ability to add tools to your LLM calls. The playground supports configuring custom tools that AI models can call during conversations.

​
Tool Definition Structure

Tools in the playground have the following structure:

  • JSON object with keys as function names
  • Each function contains two main entries:
    • description - Clear explanation of what the function does
    • parameters - JSON schema defining the input parameters structure
  • Tool choice - Controls when tools are used: none, auto, required, or specific function name

Learn more about tool choice options in the AI SDK documentation.
