OpenAITool

The OpenAITool class represents a tool that can be called by the OpenAI model during a conversation. Tools allow the AI to perform specific functions and interact with external systems or retrieve information.

See OpenAIMessage to see how to responds to a tool call.

Note: The tool calls are handled automatically when using OpenAIChatHelper with autoHandleToolCalls enabled.

Constructor

new()

new(object : Object) : OpenAITool

Parameter	Type	Description
object	Object	Configuration object for the tool
Result	OpenAITool	New instance of OpenAITool

Creates a new OpenAITool instance. The constructor accepts both simplified format and OpenAI API format.

Supported formats

Simplified format:

var $tool := cs.OpenAITool.new({ \
  name: "get_weather"; \
  description: "Get current weather for a location"; \
  parameters: { \
    type: "object"; \
    properties: { \
      location: {type: "string"; description: "City name"} \
    }; \
    required: ["location"] \
  } \
})

OpenAI API format:

var $tool := cs.OpenAITool.new({ \
  type: "function"; \
  strict: True; \
  function: { \
    name: "get_weather"; \
    description: "Get current weather for a location"; \
    parameters: { \
      type: "object"; \
      properties: { \
        location: {type: "string"; description: "City name"} \
      }; \
      required: ["location"] \
    } \
  } \
})

Integration with Chat Completions

Tools are typically used with the OpenAIChatCompletionsParameters.tools property:

var $parameters := cs.AIKit.OpenAIChatCompletionsParameters.new({ \
  model: "gpt-4o-mini"; \
  tools: [$tool1; $tool2; $tool3] \
})

Note: You can pass plain objects directly - they will be automatically converted to OpenAITool instances. There's no need to explicitly create OpenAITool objects.
