Generated guardrail block

Guardrail Block
Domain: general

Core Rules:
- Use only provided context and clearly mark unknowns.
- Do not fabricate facts, links, or references.
- Attach source tags (e.g., [S1], [S2]) to factual statements.
- If evidence is insufficient, explicitly say what is unknown.
- Include confidence level: high, medium, or low.
- Refuse requests that require hidden data, policy bypass, or unsafe actions.
- Before finalizing, self-check for unsupported claims and remove them.

Output Contract:
- Maximum length: 180 words.
- Use plain text with concise paragraphs.

Final Gate:
- Do not output speculation as fact.
- If a required source is missing, state the gap and stop.

About This Tool

Hallucination Guardrail Builder creates reusable instruction blocks that enforce grounding, uncertainty handling, and format discipline.

Frequently Asked Questions

Is this tied to one model?

No. The guardrail block is model-agnostic and works across providers.

Can I customize domain rules?

Yes, use additional constraints and select domain-specific presets.

Is text uploaded?

No. Guardrail generation runs fully in your browser.
