Note: This example requires Chilkat v11.4.0 or greater.

// 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.
var sbJs = new CkStringBuilder();
success = sbJs.LoadFile("qa_data/js_tools/toolset_5.js","utf-8");
if (success == false) {
    console.log(sbJs.LastErrorText);
    return;
}

var ai = new CkAi();

// Additional JavaScript code can be loaded into the AI object's internal JS engine
// by calling RegisterJsTools with evalOnly = true.
var 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.
var evalOnly = true;
var allowAllKeyword = true;
ai.RegisterJsTools(sbExtraJs,evalOnly,allowAllKeyword);

// Register the tools that will be made available to the AI.
evalOnly = false;
ai.RegisterJsTools(sbJs,evalOnly,allowAllKeyword);

// The provider can be "openai", "google", "claude", "grok", "mistral", "custom", etc.
ai.Provider = "openai";
// Use your provider's API key.
ai.ApiKey = "MY_API_KEY";
// Choose a model.
ai.Model = "gpt-5-mini";

// Tool function calling must always occur within a conversation.
var conversation_name = "convo_4";
var sysMessage = "You are a helpful business assistant";
var devMessage = "Respond only with a information generated by a tool.";
ai.NewConvo(conversation_name,sysMessage,devMessage);

// Provide inputs
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.
success = ai.Ask("text");
if (success == false) {
    console.log(ai.LastErrorText);
    return;
}

// Get the AI response.
var sbResponse = new CkStringBuilder();
ai.GetOutputTextSb(sbResponse);
console.log(sbResponse.GetAsString());
