(Classic ASP) Automatic JavaScript AI Tool Function Calling

See more AI Examples

Demonstrates how to do automatic tool function calling using Chilkat with embedded Chilkat.Js JavaScript. Automatic JavaScript tool calls are characterized by:

Tool function implementations are in JavaScript.
The JavaScript also provides a tool registry and permissions.
The JavaScript runs embedded within your application using Chilkat.Js.
Tool calls are handled entirely within Chilkat. Your application does not need to manually check for function calls in the AI response. Internal to the Ask function, Chilkat will handle function calls by calling your registered JavaScript tools and will send results back to the AI model until the final response is received.

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

// Tool functions must ALWAYS have just a single argument, which is an object.

// The function name used here must match the "name" in the toolRegistry below.

// By grouping get_compatibility, get_horoscope, toolRegistry, and toolPermissions under the Example object, 
// you are "namespacing" them. This tells anyone reading the code (and the JavaScript engine itself) 
// that these tools belong together and prevents them from clashing with another function that might 
// also be named get_horoscope.
