Jev Research Verification for AI Agents | AutoJev

Use Jev research verification to judge evidence coverage, contradictions, source quality and uncertainty before an AI agent cites a claim.

Last updated: 2026-09-18

Jev research verification evaluates whether the evidence collected by an agent supports a specific claim. It considers the claim, available evidence, source quality and stakes, then returns a bounded status such as supported, contradicted or insufficient.

The workflow question

Is the available evidence strong enough for the agent to rely on this claim?

This is a workflow check, not a source of new facts. AutoJev does not browse for missing evidence inside the preset. The agent must collect sources first and remain responsible for accurate citations.

Example research input

json

{
  "claim": "This order qualifies for an expedited refund under the policy",
  "evidence": ["Order arrived three days late", "Policy requires five days"],
  "source_quality": "mixed",
  "stakes": "medium"
}

An illustrative result shape is:

json

{
  "recommendation": "insufficient",
  "confidence": 0.88,
  "guidance": "Do not state eligibility. Collect the applicable policy exception or revise the claim."
}

Actual answers and probabilities depend on the supplied state and configured Jev provider.

Useful research checks

Verify whether evidence directly supports the claim being written.
Detect a contradiction between a source and the proposed conclusion.
Escalate high-stakes claims with weak or mixed-quality sources.
Keep an agent searching when a required fact remains unverified.
Prevent a citation from being used for a claim it does not establish.

Deterministic source checks still matter. Validate URLs, publication dates, access status and required authority separately.

Run the preset

Use POST /api/v1/decisions/research or open the research example in the Playground. The research-check Skill adds trigger guidance for MCP-capable agents.

Frequently asked questions

Does this replace fact checking?

No. It helps decide whether supplied evidence supports a bounded claim. It does not discover truth independently or replace authoritative verification.

Can the preset browse the web?

No. The caller supplies the evidence being evaluated.

What should happen when evidence is insufficient?

Keep the claim unpublished, gather better evidence, narrow the wording or route the decision to a human reviewer.
