Agents can validate their work against criteria before returning results.

​
Quick Start

1

Define Success Criteria

import { Agent } from 'praisonai';

const agent = new Agent({
  instructions: 'Write blog posts',
  criteria: 'Must be at least 500 words and include 3 key points'
});

const result = await agent.chat('Write about AI trends');
// Agent validates output meets criteria before returning
2

Multiple Criteria

const agent = new Agent({
  criteria: [
    'Contains at least 500 words',
    'Includes an introduction',
    'Has actionable takeaways'
  ]
});

Configuration Levels

// Level 1: String - Simple criteria
const agent = new Agent({
  criteria: 'Must be professional and concise'
});

// Level 2: Array - Multiple criteria
const agent = new Agent({
  criteria: [
    'At least 300 words',
    'Includes examples',
    'No jargon'
  ]
});

// Level 3: Dict - With options
const agent = new Agent({
  criteria: {
    rules: ['professional', 'concise'],
    maxRetries: 3,
    strict: true
  }
});

Best Practices

“At least 500 words” is better than “long enough”.
Criteria the agent can verify work best.
Prevent infinite loops with maxRetries.
