HP — Hallucination possible

Use this tag

Coming Soon. This tag has no working checker to install yet.

See How it works for its intended job. Help improve this tag to contribute or follow its progress.

Baseline job

Evaluate validated indicators of unsupported or inconsistent claims.

What the tag can claim

Possible unsupported content, only if separately validated indicators justify it.

Method and evidence

• Proposed contradiction, unsourced specificity, repetition, and hedge analysis. None ships in the current evaluator.
• Development · standard v0.1.0
• 0.65 editorial proposal; uncalibrated.

Input

Content, with references where the method requires them.

Output

A versioned tag record with subject binding, method, evidence, limitations, and a result state.

Supported scope

• Research scope only

Limits

• Dates, precise writing, repetition, or missing hedges do not establish hallucination
• Cannot be emitted by the current runtime
• Independent labels are missing

Accuracy and validation

Not independently release validated.

Cost and access

Free personal workflow. No paid detector, evidence, or verification gate.

Privacy

This catalogue does not evaluate your content. The personal reference implementation uses local services; detected redaction can miss sensitive information.

Dependencies

• Versioned claim and evidence contract
• Independent review for this tag
• Accessible presentation and a clear failure state

Failure behavior

A failed or unsupported check must not become a finding. A problem with this tag must not disable unrelated tags.

Who owns the outcome

Maintainers own implementation; independent reviewers own validation; the product owner accepts release.

Before release

Publish agreed acceptance criteria, run independent validation, and verify the complete user workflow before release.
