AutoGen middleware — automatically records multi-agent message exchanges as Truss actions.

What is Truss?

Truss is an accountability layer for AI agents — it records every agent action as a cryptographically signed, tamper-evident audit trail. Learn more →

Overview

Wrap your AutoGen agent's message handler to automatically capture the last two messages (previous agent output, current agent response) and record them as an autogen_message action. Fail-open — never blocks the agent loop.

Installation

npm install @tensflare/autogen

Quick start

import { TrussAutoGenMiddleware } from "@tensflare/autogen";

const truss = new TrussAutoGenMiddleware({
  apiUrl: "http://localhost:4000",
  apiKey: "tr_your_api_key",
  mandateId: "mnd_001",
});

// In your agent's message handler:
agent.process = truss.wrapAgent();

API

new TrussAutoGenMiddleware(options)

| Option | Type | Description | |---|---|---| | apiUrl | string | Truss API base URL | | apiKey | string | Truss API key | | mandateId | string | Mandate ID to record actions under |

middleware.wrapAgent()

Returns a wrapper function that records each message exchange as a Truss action. Captures prior output and current response, hashes both, and posts an autogen_message record.
