Automatic JS AI Tool Calling with Supporting JS Sources

See more AI Examples

Demonstrates an automatic JavaScript tool function calling where JavaScript code can be loaded from additional scripts that don't include a tool registry. Java

    // ----------------------------------------------------------------------------------
    // The Javascript file loaded here is shown at the bottom of this page.
    // -----------------------------------------------------------------------------------

    // In this example, we'll load the Javascript tool functions and registry from a file.

    success = sbJs.LoadFile("qa_data/js_tools/toolset_5.js","utf-8");

    // by calling RegisterJsTools with evalOnly = true.
    CkStringBuilder sbExtraJs = new CkStringBuilder();
    sbExtraJs.Append("function getOrderTotal({ order_id }) { return 149.95; }");

    // When evalOnly equals true, it tells Chilkat that no toolRegistry will be present.
    // The purpose for doing the eval is to add function definitions to the global namespace.
    // The value passed for allowAllKeyword is meaningless (not used) when evalOnly = true.
    boolean evalOnly = true;
    boolean allowAllKeyword = true;

    ai.InputAddText("What is the total for order A123?");

    // Send inputs, tool functions, etc. and ask for a "text" response.
    // If the AI responds with tool calls, Chilkat automatically handles them by calling your JavaScript
    // tool functions as directed by the AI, and sending results back to the AI until the final
    // response is received.
