verification

@reactive-agents/verification

Output verification for the Reactive Agents framework.

Reduces hallucinations by measuring semantic entropy (consistency across multiple samples) and decomposing claims into verifiable facts.

Installation

bun add @reactive-agents/verification

Techniques

Technique	How it works
Semantic entropy	Samples the LLM N times; high variance → low confidence
Fact decomposition	Breaks output into atomic claims, checks each independently

Usage

import { ReactiveAgents } from "reactive-agents";

const agent = await ReactiveAgents.create()
  .withName("fact-checker")
  .withProvider("anthropic")
  .withVerification()
  .build();

const result = await agent.run("What year did the Berlin Wall fall?");
console.log(result.metadata.confidence); // 0.0–1.0

When confidence is below the threshold, the agent can re-sample or escalate to the user depending on the active interaction mode.
