langchain-agentoracle

Trust verification for LangChain agents. Per-claim. Before they act.

Your LangChain agent retrieves data and acts on it. But retrieval doesn't mean truth. One hallucinated fact — a wrong acquisition, a fake statistic, stale data — cascades through your entire pipeline.

AgentOracle sits between retrieval and action. It verifies every claim first.

Install

pip install langchain-agentoracle

Quickstart

from langchain_agentoracle import AgentOracleTool
from langchain.agents import initialize_agent, AgentType
from langchain_openai import ChatOpenAI

llm = ChatOpenAI(model="gpt-4")

tools = [AgentOracleTool()]

agent = initialize_agent(
    tools,
    llm,
    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True
)

agent.run(
    "Research the latest AI agent frameworks and verify the claims before summarizing"
)

That's it. Your agent now verifies before acting.

Recommendation logic

Score	Recommendation	What your agent should do
> 0.8	act	Proceed — claims verified
0.5–0.8	verify	Pause — needs secondary check
< 0.5	reject	Discard — evidence insufficient

---

How it works

Every evaluation runs through 4 independent sources in parallel:

1. Sonar — real-time web research
2. Sonar Pro — deep multi-step analysis
3. Adversarial — actively tries to disprove the claim
4. Gemma 4 — claim decomposition and confidence calibration

Consensus builds the score. Contradiction flags the risk.
