Overview

AgentJudgeEval evaluates agent responses against multiple custom criteria using an LLM judge. Supports both numeric scoring (0.0–1.0) and binary (PASS/FAIL) modes.

​
Quick Start

import { AgentJudgeEval } from "@agentium/eval";
import { Agent, openai } from "@agentium/core";

const agent = new Agent({ name: "writer", model: openai("gpt-4o") });

const eval = new AgentJudgeEval({
  name: "writing-quality",
  agent,
  judge: openai("gpt-4o-mini"),
  criteria: [
    "Response is grammatically correct",
    "Response is concise (under 200 words)",
    "Response directly answers the question",
  ],
  scoringMode: "numeric",
  cases: [
    { name: "explain-recursion", input: "Explain recursion in simple terms" },
  ],
});

const result = await eval.run();

​
Scoring Modes

  • numeric (default): Each criterion scored 0.0–1.0
  • binary: Each criterion scored PASS (1.0) or FAIL (0.0)
