📚 Tawk Agents SDK - Documentation

Production-ready AI agent framework with comprehensive observability

Welcome to the Tawk Agents SDK documentation! This guide covers everything from your first agent to enterprise-scale multi-agent systems.

🚀 Quick Start

import { Agent, run } from '../../src';
import { openai } from '@ai-sdk/openai';

const agent = new Agent({
  name: 'Assistant',
  model: openai('gpt-4o'),
  instructions: 'You are a helpful assistant.'
});

const result = await run(agent, 'Hello!');
console.log(result.finalOutput);

📊 Quick Examples

Basic Agent

import { Agent, run } from '../../src';
import { openai } from '@ai-sdk/openai';

const agent = new Agent({
  name: 'Assistant',
  model: openai('gpt-4o'),
  instructions: 'You are helpful.'
});

const result = await run(agent, 'Hello!');

Agent with Tools

import { Agent, run, tool } from '../../src';
import { z } from 'zod';

const calculator = tool({
  description: 'Do math',
  inputSchema: z.object({
    a: z.number(),
    b: z.number()
  }),
  execute: async ({ a, b }) => a + b
});

const agent = new Agent({
  name: 'Math',
  model: openai('gpt-4o'),
  tools: { calculator }
});

const result = await run(agent, 'What is 5 + 3?');

Multi-Agent System

const specialist = new Agent({
  name: 'Specialist',
  model: openai('gpt-4o'),
  instructions: 'You specialize in data analysis.'
});

const coordinator = new Agent({
  name: 'Coordinator',
  model: openai('gpt-4o'),
  instructions: 'Route tasks to specialists.',
  subagents: [specialist]  // Auto-creates transfer tools
});

const result = await run(coordinator, 'Analyze sales data');

With Guardrails

import { lengthGuardrail, piiDetectionGuardrail } from '../../src';

const agent = new Agent({
  name: 'Safe',
  model: openai('gpt-4o'),
  guardrails: [
    lengthGuardrail({ type: 'output', maxLength: 500 }),
    piiDetectionGuardrail({ type: 'output', block: true })
  ]
});

With Tracing

import { initLangfuse, Agent, run } from '../../src';

initLangfuse(); // Reads LANGFUSE_* env vars

const agent = new Agent({ /* ... */ });
const result = await run(agent, 'Query');
// Automatically traced to Langfuse with complete execution hierarchy

With Sessions

import { MemorySession } from '../../src';

const session = new MemorySession('user-123', 50);

const result1 = await run(agent, 'My name is Alice', { session });
const result2 = await run(agent, 'What is my name?', { session });
// Agent maintains context: "Your name is Alice"
