Dart Requires Chilkat v11.4.0+

AI Ask with Multiple Tool Function Callbacks

See more AI Examples

This example demonstrates asking a two-part question that should cause the AI to respond with two tool call requests. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // ----------------------------------------------------------------------------------
  // The Javascript file loaded here is shown at the bottom of this page.
  // -----------------------------------------------------------------------------------

  // Load JavaScript containing the tool functions.
  final sbJs = CkStringBuilder();
  try {
    sbJs.loadFile('qa_data/js_tools/toolset_6.js', 'utf-8');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final ai = CkAi();

  // Register the tools that will be made available to the AI.
  final evalOnly = false;
  final allowAllKeyword = true;
  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-5.6-luna';

  // Tool function calling must always occur within a conversation.
  final conversationName = 'example_convo';
  final sysMessage = 'You are a helpful assistant';
  final devMessage = 'Respond with markdown';
  ai.newConvo(conversationName, sysMessage, devMessage);

  // Provide inputs
  ai.inputAddText('What is my horoscope? I am an Aquarius.  Also, what\'s the weather in Chicago?');

  // 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.
  try {
    ai.ask('text');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Get the AI response.
  final sbResponse = CkStringBuilder();
  ai.getOutputTextSb(sbResponse);
  print(sbResponse.getAsString());
}

JavaScript

// The namespace for the AI tool functions in this JavaScript source file.
Example = {};

// Tool functions must have only one argument, which should be an object.

// The function name used here must match the "name" in the toolRegistry below.
Example.get_weather = function(arg) {
  return {
	  "temperature": 45,
	  "unit": "F",
	  "conditions": "Cloudy"
	};
}

Example.get_horoscope = function(arg) {
  return  `${arg.sign} : Next Tuesday you will befriend a baby otter.`;
}



// The inputSchema.type must ALWAYS be "object".
Example.toolRegistry = [
  {
    name: "get_horoscope",
    description: "Get today's horoscope for an astrological sign.",
    parameters: {
      properties: {
        sign: { type: "string", description: "An astrological sign like Taurus or Aquarius" }
      }
    }
  },
  {
    name: "get_weather",
    description: "Gets the weather at a location.",
    parameters: {
      properties: {
        location: { type: "string", description: "Location such as a city name." },
      }
    }
  }
];


Example.toolPermissions = [
	  {
	    name: "all",
	    perm: "sandbox",
	  }
	  		
	];
	
	
// Return the name of this toolset
// This tells Chilkat the namespace of this toolset.
