AutoRag Agent - PraisonAI

Automatically retrieve relevant context based on query analysis with AutoRagAgent.

Quick Start

Create AutoRagAgent

import { AutoRagAgent, RetrievalPolicy } from 'praisonai';

const autoRag = new AutoRagAgent({
  retrievalPolicy: RetrievalPolicy.AUTO,
  topK: 5,
  rerank: true
});

Check if Retrieval Needed

// Queries that trigger retrieval
autoRag.shouldRetrieve("What is machine learning?");  // true
autoRag.shouldRetrieve("Explain the document");       // true
autoRag.shouldRetrieve("Find information about AI");  // true

// Queries that don't trigger retrieval
autoRag.shouldRetrieve("Hi");                         // false
autoRag.shouldRetrieve("Thanks");                     // false

Retrieval Policies

import { RetrievalPolicy } from 'praisonai';

RetrievalPolicy.AUTO    // Smart detection based on query
RetrievalPolicy.ALWAYS  // Always retrieve context
RetrievalPolicy.NEVER   // Never retrieve context

Configuration

import { AutoRagAgent, AutoRagAgentConfig, RetrievalPolicy } from 'praisonai';

const config: AutoRagAgentConfig = {
  retrievalPolicy: RetrievalPolicy.AUTO,
  topK: 5,                    // Number of results to retrieve
  hybrid: false,              // Use hybrid search
  rerank: true,               // Rerank results
  includeCitations: true,     // Include citations in response
  citationsMode: 'append',    // 'append' | 'hidden' | 'none'
  maxContextTokens: 4000,     // Max tokens for context
  autoMinLength: 10           // Min query length for auto mode
};

const autoRag = new AutoRagAgent(config);

Configuration Options

Option	Type	Default	Description
`retrievalPolicy`	`RetrievalPolicy`	`AUTO`	When to retrieve context
`topK`	`number`	`5`	Number of results to retrieve
`hybrid`	`boolean`	`false`	Use hybrid (keyword + semantic) search
`rerank`	`boolean`	`false`	Rerank results for relevance
`includeCitations`	`boolean`	`true`	Include source citations
`citationsMode`	`string`	`'append'`	How to show citations
`maxContextTokens`	`number`	`4000`	Max context window
`autoMinLength`	`number`	`10`	Min query length for AUTO

Auto Keywords

Queries containing these keywords trigger retrieval in AUTO mode:

import { DEFAULT_AUTO_KEYWORDS } from 'praisonai';

// Default keywords that trigger retrieval
const keywords = [
  'what', 'how', 'why', 'when', 'where', 'who', 'which',
  'explain', 'describe', 'summarize', 'find', 'search',
  'tell me', 'show me', 'according to', 'based on',
  'cite', 'source', 'reference', 'document', 'paper'
];

Custom Keywords

const autoRag = new AutoRagAgent({
  retrievalPolicy: RetrievalPolicy.AUTO,
  autoKeywords: new Set([
    'what', 'how', 'explain',
    'my custom keyword',
    'another trigger'
  ])
});

Methods

shouldRetrieve

Check if a query should trigger retrieval:

const autoRag = new AutoRagAgent();

// Returns true for questions
autoRag.shouldRetrieve("What is the capital of France?");  // true

// Returns true for search queries
autoRag.shouldRetrieve("Find documents about AI");         // true

// Returns false for short queries
autoRag.shouldRetrieve("Hi");                              // false

// Returns false for non-question statements
autoRag.shouldRetrieve("Thanks for your help");            // false

getConfig

Get the current configuration:

const config = autoRag.getConfig();
console.log(config.topK);           // 5
console.log(config.retrievalPolicy); // 'auto'

Common Patterns

With Knowledge Base
With Agent

import { AutoRagAgent, RetrievalPolicy, Knowledge } from 'praisonai';

const knowledge = new Knowledge({
  sources: ['./docs'],
  embeddings: 'text-embedding-3-small'
});

const autoRag = new AutoRagAgent({
  retrievalPolicy: RetrievalPolicy.AUTO,
  topK: 5,
  rerank: true
});

async function answer(query: string) {
  if (autoRag.shouldRetrieve(query)) {
    const context = await knowledge.search(query, { topK: 5 });
    return generateWithContext(query, context);
  }
  return generateDirect(query);
}

import { Agent, AutoRagAgent, RetrievalPolicy } from 'praisonai';

const autoRag = new AutoRagAgent({
  retrievalPolicy: RetrievalPolicy.AUTO
});

const agent = new Agent({
  name: "RAG Assistant",
  instructions: "Answer questions using retrieved context"
});

async function chat(query: string) {
  const needsContext = autoRag.shouldRetrieve(query);
  
  if (needsContext) {
    // Add context to the query
    const context = await retrieveContext(query);
    return agent.start(`Context: ${context}\n\nQuestion: ${query}`);
  }
  
  return agent.start(query);
}

Best Practices

Use AUTO for general chatbots

AUTO mode balances retrieval costs with response quality for most use cases.

Use ALWAYS for document Q&A

When every query relates to documents, use ALWAYS to ensure context is included.

Enable reranking for accuracy

Reranking improves result relevance at a small latency cost.

Tune autoMinLength

Increase autoMinLength to avoid retrieval for very short queries.
