setNativeFunctions | SignalWire

Set the list of native SWAIG functions to enable. Native functions are built into the SignalWire platform and execute server-side without requiring a webhook. They provide common utility operations that the AI can invoke during a conversation.

Native functions can also be passed at construction time via the nativeFunctions constructor option.

Parameters

funcs

string[]Required

Array of native function names to enable. Common native functions include:

"check_time" — Get the current time in a given timezone
"wait_for_user" — Pause the AI and wait for the caller to speak
"next_step" — Advance to the next step in a context workflow
"transfer" — Transfer the call to another number or agent

Returns

AgentBase — Returns this for method chaining.

import { AgentBase } from '@signalwire/sdk';
const agent = new AgentBase({ name: 'assistant', route: '/assistant' });
agent.setPromptText('You are a helpful assistant.');
agent.setNativeFunctions(['check_time', 'wait_for_user']);
await agent.serve();

Set at construction time

import { AgentBase } from '@signalwire/sdk';
const agent = new AgentBase({
  name: 'assistant',
  route: '/assistant',

});
agent.setPromptText('You are a helpful assistant.');
await agent.serve();
