## Overview

`workflow-function-manifold` enables you to create dynamic workflows that:
- Navigate between different execution regions based on LLM-interpreted intents
- Execute operations within regions based on state and context
- Maintain workflow state across operations
- Support flexible region-to-region connections

## Installation

```bash
npm install workflow-function-manifold
```

## Quick Start

```javascript
import { 
  WorkflowFunctionManifold, 
  ManifoldRegion, 
  WorkflowOperator, 
  DummyLlmService 
} from 'workflow-function-manifold';

// Initialize the manifold with an LLM service
const llm = new DummyLlmService();
const manifold = new WorkflowFunctionManifold(llm);

// Create an operator
const analysisOperator = new WorkflowOperator('analysis', async (state) => {
  console.log('Analyzing data...');
  return { ...state, analyzed: true };
});

// Create and connect regions
const analysisRegion = new ManifoldRegion('analysis', [analysisOperator]);
manifold.addRegion(analysisRegion);

// Execute workflow
await manifold.navigate('analyze the data');
await manifold.executeWorkflow('analyze the data');
```

## Core Components

### WorkflowFunctionManifold

The main class that orchestrates workflow execution.

```javascript
const manifold = new WorkflowFunctionManifold(llmService);

// Add regions
manifold.addRegion(region);

// Navigate between regions
await manifold.navigate(prompt);

// Execute operations
await manifold.executeWorkflow(prompt);
```

### ManifoldRegion

Represents a workflow region containing operators and connections to other regions.

```javascript
const region = new ManifoldRegion('regionName', [operator1, operator2]);

// Connect regions
region.connectTo(otherRegion);

// Add operators
region.addOperator(newOperator);
```

### WorkflowOperator

Defines operations that can be executed within regions.

```javascript
const operator = new WorkflowOperator('operatorName', async (state) => {
  // Modify state
  return newState;
});
```

### DummyLlmService

A simple LLM service simulation for intent matching.

```javascript
const llm = new DummyLlmService();
const intent = await llm.query('analyze the data');
// Returns: { confidence: 0.9, action: 'analysis' }
```

## Complete Example

Here's a full example demonstrating a three-stage workflow:

```javascript
async function createWorkflow() {
  const llm = new DummyLlmService();
  const manifold = new WorkflowFunctionManifold(llm);

  // Create operators
  const analysisOp = new WorkflowOperator('analysis', async (state) => {
    return { ...state, analyzed: true };
  });
  const processingOp = new WorkflowOperator('processing', async (state) => {
    return { ...state, processed: true };
  });
  const transformOp = new WorkflowOperator('transformation', async (state) => {
    return { ...state, transformed: true };
  });

  // Create and connect regions
  const analysisRegion = new ManifoldRegion('analysis', [analysisOp]);
  const processingRegion = new ManifoldRegion('processing', [processingOp]);
  const transformRegion = new ManifoldRegion('transformation', [transformOp]);

  analysisRegion.connectTo(processingRegion);
  processingRegion.connectTo(transformRegion);

  // Add regions to manifold
  manifold.addRegion(analysisRegion);
  manifold.addRegion(processingRegion);
  manifold.addRegion(transformRegion);

  return manifold;
}

// Execute workflow
const manifold = await createWorkflow();
const prompts = [
  'analyze the data',
  'process the results',
  'transform the output'
];

for (const prompt of prompts) {
  await manifold.navigate(prompt);
  await manifold.executeWorkflow(prompt);
}
```

## API Reference

### WorkflowFunctionManifold

#### Constructor
- `constructor(llmService: LLMService)`

#### Methods
- `addRegion(region: ManifoldRegion): void`
- `async navigate(prompt: string): Promise<boolean>`
- `async executeWorkflow(prompt: string): Promise<boolean>`

### ManifoldRegion

#### Constructor
- `constructor(name: string, operators: WorkflowOperator[] = [])`

#### Methods
- `addOperator(operator: WorkflowOperator): void`
- `connectTo(region: ManifoldRegion): void`
- `async getValidOperators(state: any): Promise<WorkflowOperator[]>`

### WorkflowOperator

#### Constructor
- `constructor(name: string, operation: (state: any) => Promise<any>)`

#### Methods
- `async execute(state: any): Promise<any>`

## State Management

The workflow maintains state across operations. Each operator can access and modify the state:

```javascript
const operator = new WorkflowOperator('example', async (state) => {
  // Access existing state
  const { previousValue } = state;
  
  // Return modified state
  return {
    ...state,
    newValue: 'updated'
  };
});
```

## LLM Integration

The system uses LLM services for intent recognition. The default `DummyLlmService` provides basic intent matching, but you can implement your own LLM service:

```javascript
class CustomLLMService {
  async query(prompt) {
    // Implement custom LLM logic
    return {
      confidence: number,
      action: string
    };
  }
}
```
