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. Swift

func chilkatTest() {
    var success: Bool = false

    // ----------------------------------------------------------------------------------
    // 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.
    let sbJs = CkoStringBuilder()!
    success = sbJs.loadFile(path: "qa_data/js_tools/toolset_5.js", charset: "utf-8")
    if success == false {
        print("\(sbJs.lastErrorText!)")
        return
    }

    let ai = CkoAi()!

    // Additional JavaScript code can be loaded into the AI object's internal JS engine
    // by calling RegisterJsTools with evalOnly = true.
    let sbExtraJs = CkoStringBuilder()!
    sbExtraJs.append(value: "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: Bool = true
    var allowAllKeyword: Bool = true
    ai.registerJsTools(sb: sbExtraJs, evalOnly: evalOnly, allowAllKeyword: allowAllKeyword)

    // Register the tools that will be made available to the AI.
    evalOnly = false
    ai.registerJsTools(sb: sbJs, evalOnly: evalOnly, allowAllKeyword: 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: String? = "convo_4"
    var sysMessage: String? = "You are a helpful business assistant"
    var devMessage: String? = "Respond only with a information generated by a tool."
    ai.newConvo(name: conversation_name, sysMsg: sysMessage, devMsg: devMessage)

    // Provide inputs
    ai.inputAddText(text: "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(outputType: "text")
    if success == false {
        print("\(ai.lastErrorText!)")
        return
    }

    // Get the AI response.
    let sbResponse = CkoStringBuilder()!
    ai.getOutputTextSb(sb: sbResponse)
    print("\(sbResponse.getAsString()!)")
