Introducing WorkflowDrivenAgent: Deterministic AI Workflows in KaibanJS

This content originally appeared on DEV Community and was authored by Dariel Vila

The world of multi-agent AI systems is evolving rapidly, and while LLM-based agents excel at creative problem-solving, there's a growing need for deterministic, repeatable processes in production environments. Today, we're excited to introduce the WorkflowDrivenAgent in KaibanJS, a game-changing approach that combines the power of structured workflows with seamless multi-agent orchestration.

What is KaibanJS?

KaibanJS is a powerful multi-agent framework that enables developers to build sophisticated AI systems with multiple specialized agents working together. Think of it as your AI team orchestrator, where each agent has specific roles, tools, and capabilities, all coordinated through an intuitive task-based system.

Key Features of KaibanJS:

🤖 Multi-Agent Orchestration: Coordinate multiple AI agents seamlessly
🔧 Tool Integration: Connect agents with external APIs, databases, and services
📊 Real-time Monitoring: Track agent performance and workflow execution
🔄 Task Chaining: Create complex workflows with dependent tasks
🎯 Type Safety: Full TypeScript support with robust error handling
🌐 Framework Agnostic: Works with React, Vue, Node.js, and more

The Problem with Pure LLM Agents

Traditional LLM-based agents (like KaibanJS's ReactChampionAgent) are fantastic for tasks requiring creativity and dynamic decision-making. However, they have limitations:

// Traditional LLM Agent - Great for creative tasks
const creativAgent = new Agent({
  type: 'ReactChampionAgent',
  name: 'Creative Writer',
  role: 'Content Creator',
  goal: 'Write engaging blog posts',
  background: 'Expert copywriter with 10 years experience',
});

Challenges:

❌ Non-deterministic: Same input might produce different outputs
❌ Costly: Every decision requires LLM calls
❌ Complex debugging: Hard to trace execution paths
❌ Limited control: Difficult to enforce specific business logic

Enter WorkflowDrivenAgent

The WorkflowDrivenAgent solves these challenges by executing predefined workflows instead of relying on LLM reasoning for every step. It's perfect for structured, repeatable processes while still allowing LLM integration where needed.

Key Advantages:

✅ Deterministic: Same input = same output, every time
✅ Cost-effective: No LLM calls for workflow orchestration
✅ Type-safe: Full schema validation with Zod
✅ Debuggable: Clear execution paths and state tracking
✅ Flexible: Mix deterministic steps with LLM-powered operations

Basic Implementation

Let's start with a simple example:

import { Agent, Task, Team } from 'kaibanjs';
import { createStep, createWorkflow } from '@kaibanjs/workflow';
import { z } from 'zod';

// Step 1: Add two numbers
const addStep = createStep({
  id: 'add',
  inputSchema: z.object({ a: z.number(), b: z.number() }),
  outputSchema: z.number(),
  execute: async ({ inputData }) => {
    const { a, b } = inputData;
    console.log(`Adding ${a} + ${b}`);
    return a + b;
  },
});

// Step 2: Multiply by original inputs
const multiplyStep = createStep({
  id: 'multiply',
  inputSchema: z.number(),
  outputSchema: z.number(),
  execute: async ({ inputData, getInitData }) => {
    const sum = inputData;
    const { a, b } = getInitData();
    return sum * a * b;
  },
});

// Create the workflow
const mathWorkflow = createWorkflow({
  id: 'math-workflow',
  inputSchema: z.object({ a: z.number(), b: z.number() }),
  outputSchema: z.number(),
});

// Build workflow: add -> multiply
mathWorkflow.then(addStep).then(multiplyStep);
mathWorkflow.commit();

// Create the WorkflowDrivenAgent
const workflowAgent = new Agent({
  type: 'WorkflowDrivenAgent',
  name: 'Math Processor',
  workflow: mathWorkflow,
});

Advanced Patterns

1. Conditional Branching

const processStep = createStep({
  id: 'process',
  inputSchema: z.object({ value: z.number() }),
  outputSchema: z.object({ result: z.string(), isPositive: z.boolean() }),
  execute: async ({ inputData }) => {
    const { value } = inputData;
    return {
      result: `Processed: ${value}`,
      isPositive: value > 0,
    };
  },
});

const positiveStep = createStep({
  id: 'positive',
  inputSchema: z.object({ result: z.string(), isPositive: z.boolean() }),
  outputSchema: z.string(),
  execute: async ({ inputData }) => {
    return `${inputData.result} - This is a positive number!`;
  },
});

const negativeStep = createStep({
  id: 'negative',
  inputSchema: z.object({ result: z.string(), isPositive: z.boolean() }),
  outputSchema: z.string(),
  execute: async ({ inputData }) => {
    return `${inputData.result} - This is a negative number!`;
  },
});

// Conditional workflow
workflow.then(processStep).branch([
  [async ({ inputData }) => inputData.isPositive, positiveStep],
  [async () => true, negativeStep], // fallback
]);

2. Parallel Processing

const workflow = createWorkflow({
  id: 'parallel-processing',
  inputSchema: z.array(z.number()),
  outputSchema: z.array(z.number()),
});

// Process multiple items in parallel with concurrency control
workflow.foreach(processItemStep, { concurrency: 5 });
workflow.commit();

3. Suspend and Resume

Perfect for workflows requiring human approval:

const approvalStep = createStep({
  id: 'approval',
  inputSchema: z.object({ amount: z.number() }),
  outputSchema: z.object({ approved: z.boolean() }),
  resumeSchema: z.object({ approved: z.boolean() }),
  suspendSchema: z.object({ reason: z.string() }),
  execute: async ({ inputData, suspend, isResuming, resumeData }) => {
    if (isResuming) {
      return { approved: resumeData.approved };
    }

    if (inputData.amount > 1000) {
      // Suspend for manual approval
      await suspend({ reason: 'requires_manual_approval' });
      return { approved: false };
    }

    return { approved: true };
  },
});

Integrating LLM SDKs in Workflows

One of the most powerful features is the ability to use any LLM SDK within workflow steps:

import { generateText } from 'ai';
import { createOpenAI } from '@ai-sdk/openai';
import { ChatOpenAI } from '@langchain/openai';

// Step using Vercel AI SDK
const aiAnalysisStep = createStep({
  id: 'ai-analysis',
  inputSchema: z.object({ data: z.string() }),
  outputSchema: z.object({ analysis: z.string(), confidence: z.number() }),
  execute: async ({ inputData }) => {
    const { text } = await generateText({
      model: createOpenAI()('gpt-4o-mini'),
      prompt: `Analyze this data: ${inputData.data}`,
      temperature: 0.3,
    });

    return {
      analysis: text,
      confidence: 0.85,
    };
  },
});

// Step using LangChain
const langchainStep = createStep({
  id: 'langchain-search',
  inputSchema: z.object({ query: z.string() }),
  outputSchema: z.object({ results: z.string() }),
  execute: async ({ inputData }) => {
    const model = new ChatOpenAI({
      modelName: 'gpt-4o-mini',
      temperature: 0,
    });

    const result = await model.invoke([
      { role: 'user', content: `Search for: ${inputData.query}` },
    ]);

    return { results: result.content };
  },
});

Mixed Teams: Best of Both Worlds

Combine WorkflowDrivenAgent with traditional LLM agents:

const team = new Team({
  name: 'Hybrid AI Team',
  agents: [
    // Deterministic data processing
    new Agent({
      type: 'WorkflowDrivenAgent',
      name: 'Data Processor',
      workflow: dataProcessingWorkflow,
    }),
    // Creative analysis
    new Agent({
      type: 'ReactChampionAgent',
      name: 'Creative Analyst',
      role: 'Data Analyst',
      goal: 'Provide creative insights on processed data',
      background: 'Expert in data interpretation and storytelling',
    }),
  ],
  tasks: [
    new Task({
      description: 'Process and validate the input data',
      expectedOutput: 'Clean, validated dataset',
      agent: 'Data Processor',
    }),
    new Task({
      description: 'Generate creative insights from the processed data',
      expectedOutput: 'Strategic recommendations and insights',
      agent: 'Creative Analyst',
    }),
  ],
});

const result = await team.start({ rawData: userData });

Real-World Use Cases

1. Data Processing Pipeline

// ETL workflow with validation, transformation, and loading
const etlWorkflow = createWorkflow({
  id: 'etl-pipeline',
  inputSchema: z.object({ rawData: z.array(z.any()) }),
  outputSchema: z.object({
    processedRecords: z.number(),
    errors: z.array(z.string()),
  }),
});

etlWorkflow.then(validateDataStep).then(transformDataStep).then(loadDataStep);

2. Content Moderation

// Automated content review with human escalation
const moderationWorkflow = createWorkflow({
  id: 'content-moderation',
  inputSchema: z.object({ content: z.string(), userId: z.string() }),
  outputSchema: z.object({ approved: z.boolean(), reason: z.string() }),
});

moderationWorkflow.then(autoModerationStep).branch([
  [async ({ inputData }) => inputData.confidence > 0.9, approveStep],
  [async () => true, humanReviewStep], // Suspend for human review
]);

3. Financial Processing

// Transaction processing with compliance checks
const transactionWorkflow = createWorkflow({
  id: 'transaction-processing',
  inputSchema: z.object({
    amount: z.number(),
    fromAccount: z.string(),
    toAccount: z.string(),
  }),
  outputSchema: z.object({
    transactionId: z.string(),
    status: z.enum(['completed', 'pending', 'rejected']),
  }),
});

transactionWorkflow
  .then(validateAccountsStep)
  .then(checkBalanceStep)
  .then(complianceCheckStep)
  .branch([
    [async ({ inputData }) => inputData.amount > 10000, manualApprovalStep],
    [async () => true, processTransactionStep],
  ]);

Monitoring and Observability

WorkflowDrivenAgent provides excellent observability:

// Real-time monitoring
const run = workflow.createRun();

// Subscribe to workflow events
const unsubscribe = run.watch((event) => {
  console.log('Event:', event.type);
  console.log('Step:', event.payload?.stepId);
  console.log('Status:', event.payload?.stepStatus);
});

// Stream execution for real-time updates
const { stream, getWorkflowState } = run.stream({
  inputData: { query: 'AI trends 2024' },
});

const reader = stream.getReader();
while (true) {
  const { done, value } = await reader.read();
  if (done) break;

  console.log('Live update:', value);
}
