$message.addImageURL("http://example.com/image.jpg"; "high")

Respond to a tool call message

When an assistant needs to use external functions, it generates a message with tool_calls to request function execution.

Assistant message requesting tool calls:

{
  "role": "assistant",
  "tool_calls": [
    {
      "id": "call_12345",
      "type": "function",
      "function": {
        "name": "get_database_tables",
        "arguments": "{}"
      }
    }
  ]
}

Handling the tool call:

When you receive a tool call message, you need to:

1. Extract the function information:

   • function.name: The name of the function to call (must match a function defined in your OpenAITool - you can select code to execute according to this name)
   • function.arguments: A JSON string containing the function parameters that must be parsed with JSON Parse
   • id: The unique identifier for this specific tool call

2. Execute the function: Parse the arguments (which is a JSON string) and call the corresponding function that you defined in your OpenAITool configuration.

3. Respond with the tool result: Create a response message using the exact tool_call_id from the original request.

Example tool response:

// Parse the function arguments (if any)
var $arguments : Object := JSON Parse($toolCall.function.arguments)

// Execute your code corresponding to "get_database_tables" 
var $tableNames: Text := OB Keys(ds).join(", ")

// Create the tool response message with the required tool_call_id
var $toolResponse:=cs.AIKit.OpenAIMessage.new({ \
  role: "tool"; \
  tool_call_id: "call_12345"; \
  content: $tableNames \
})
// Add it to the conversation and continue

Important: The tool_call_id in your response must exactly match the id from the original tool call. This allows the AI model to correctly associate your response with the specific function call that was made.
