agent

Call Signature

function agent<T>(signature: T, config: AxAgentConfig<ParseSignature<T>["inputs"], ParseSignature<T>["outputs"]>): AxAgent<ParseSignature<T>["inputs"], ParseSignature<T>["outputs"]>;

Defined in: https://github.com/ax-llm/ax/blob/d2df625e2c2fd70a090d6321c042579c2819f0d1/src/ax/prompts/agent.ts#L682

Creates a strongly-typed AI agent from a signature. This is the recommended way to create agents, providing better type inference and cleaner syntax. Supports both string signatures and AxSignature objects.

Example

// Using string signature
const myAgent = agent('userInput:string -> responseText:string', {
  name: 'myAgent',
  description: 'An agent that processes user input and returns a response',
  definition: 'You are a helpful assistant that responds to user queries...'
});

// Using AxSignature object
const sig = s('userInput:string -> responseText:string');
const myAgent2 = agent(sig, {
  name: 'myAgent2',
  description: 'Same agent but using AxSignature object'
});

// With child agents
const parentAgent = agent('taskDescription:string -> completedTask:string', {
  name: 'parentAgent',
  description: 'Coordinates child agents to complete tasks',
  agents: [childAgent1, childAgent2]
});

// Type-safe usage
const result = await myAgent.forward(ai, { userInput: 'Hello!' });
console.log(result.responseText); // TypeScript knows this exists

Type Parameters
