Without this playbook

Most teams handle ai hallucination & factual accuracy through scattered call reviews, manager opinion, and isolated examples. Without a shared operational definition, the signals stay inconsistent and difficult to act on across volume.

With this playbook

A shared, repeatable lens for ai hallucination & factual accuracy - with structured outputs you can route into coaching, reporting, and workflow automation. Every conversation produces evidence, not just opinions.

Built for

AI product managers, ML engineers, and trust & safety teams

When teams use it

  • Model evaluation and release gates
  • Governance review and policy enforcement
  • Safety and accuracy monitoring

The operational stack

3 kits behind this playbook

AI hallucination is not a single failure mode - it ranges from confidently wrong facts to subtly unsupported claims. This stack separates the problem into three layers: verification against approved knowledge sources to catch outright factual errors, unsupported claim detection to flag assertions that lack grounding even if they sound plausible, and a confidence score that measures how well-supported the overall output is. This lets teams distinguish between a hallucinated fact and a poorly grounded inference, which require different fixes.

Accuracy Verification Kit

3 bricks

Cross-references facts against approved sources to detect errors in AI or semantic output.

Verifiable Claims

String list

Extracts factual claims from input that can be verified

Claim Supported By Kb

Boolean

Checks whether each claim has support in the reference knowledge base

Unsupported Claim Present

Boolean

Knowledge base

Supporting materials

The kits in this playbook work best when backed by reference materials that ground the evaluation. Upload these into your workspace knowledge base to improve accuracy and relevance.

Structured output

What you get back

Every conversation processed through this stack produces a structured JSON object. Each brick contributes a typed field - booleans, scores, categories, or string lists - that you can route, aggregate, and report on.

Example output shape

{
  "verifiable_claims": [
    "signal 1",
    "signal 2"
  ],
  "factual_accuracy_score": 7,
  "unsupported_claim_present": true,
  "factual_support_score": 7,
  "claim_supported_by_kb": true
}
