Prompt Management

MutagenT provides a complete prompt management system with versioning, variables, and lifecycle management. Centralize your prompts, track changes, and optimize performance systematically.

​
Prompt Lifecycle

Each stage in the lifecycle builds on the previous. Start with a draft, test in the playground, validate with datasets, optimize automatically, and deploy with confidence.

​
Key Features

Version Control

Track changes with full version history. Compare versions, rollback when needed, and maintain audit trails.

Template Variables

Dynamic content with type-safe variables. Create reusable templates that adapt to different inputs.

Evaluation

Measure quality with automated testing. Use G-Eval, semantic similarity, and custom metrics.

Optimization

Automatically improve prompts through AI-driven mutation and selection cycles.

​
Prompt Structure

interface Prompt {
  id: string;                           // Unique identifier
  workspaceId: string;                  // Parent workspace
  promptGroupId: string;                // Links all versions together
  name: string;                         // Display name
  description?: string;                 // Optional description
  content: string;                      // The prompt template
  variables: Record<string, string>;    // Variable definitions
  currentVersion: number;               // Active version number
  status: 'draft' | 'published';        // Publication status
  createdAt: Date;
  updatedAt: Date;
}

​
Quick Example

import { Mutagent } from '@mutagent/sdk';

const client = new Mutagent({ bearerAuth: 'sk_live_...' });

// Create a new prompt
const prompt = await client.prompts.create({
  name: 'Customer Support',
  content: `You are a support agent for {{company_name}}.

Help the customer with their question:
{{customer_question}}

Be helpful, professional, and concise.`,
  variables: {
    company_name: 'string',
    customer_question: 'string',
  },
  description: 'Main customer support prompt template',
});

console.log('Created prompt:', prompt.id);

​
Prompt Organization

Organize prompts effectively within your workspace:
Use clear, descriptive names that indicate the prompt’s purpose:
  • customer-support-v1
  • code-review-assistant
  • data-extraction-json
Add descriptions to document:
  • What the prompt does
  • Expected inputs and outputs
  • Any special considerations
