Stop Debugging Agent Drift

Your AI agent works perfectly in staging with mock data—but fails in production when APIs respond differently. Persona Manager captures environment state so your agents behave consistently everywhere.

How Agent Personas Work

Four steps to environment consistency. Capture once, deploy everywhere.

1

Capture

Install the SDK and add one line of code. At agent initialization, Persona Manager snapshots all environment variables, tool versions, and API configs.

2

Version

Each capture creates a versioned persona. Personas are stored as JSON—track changes, compare versions, and rollback to any previous state.

3

Diff

Compare any two personas side-by-side. See exactly what differs between dev and prod—API versions, rate limits, memory state, auth tokens.

4

Replay

Before deploying, load the target environment's persona into your agent. If drift is detected, get alerted before it hits production.

Everything You Need for Environment Consistency

Built for AI engineering teams who ship agents to production.

Environment Capture SDK

One-line integration. Captures API endpoints, tool versions, rate limits, prompt configs, and memory state. Works with LangChain, CrewAI, and AutoGen.

npm install @persona-manager/sdk

Persona Dashboard

View all your agent personas in one place. Filter by environment, agent, or date. See parity status at a glance with color-coded drift indicators.

Diff Viewer

Side-by-side comparison of any two personas. Inline highlighting of added, removed, and changed values. Export diffs as JSON or markdown.

Parity Alerts

Get notified when environment drift is detected. Configure thresholds and alert channels—email, Slack, or Discord webhook.

Instant Rollback

Something broke? Roll back to any previous persona version with one click. Your agent inherits the exact environment state that worked before.

Config-as-Code

Personas are stored as versioned JSON. Commit them to git, diff them in pull requests, and integrate them into your CI/CD pipeline.

Two Lines of Code. Zero Headaches.

Integrate Persona Manager into your agent in under 5 minutes.

TypeScript
// 1. Install the SDK
npm install @persona-manager/sdk

// 2. Import and initialize
import { PersonaManager } from '@persona-manager/sdk';

const persona = new PersonaManager({
  agent_id: 'customer-support-agent',
  environment: 'production',
  auto_capture: true,  // Capture everything automatically
});

// That's it! Your persona is captured and synced.
// Access at app.personamanager.ai/dashboard
