Why it matters
Guardrails block policy violations at runtime: prohibited claims, missing citations, out-of-scope advice, toxic outputs. They translate policy into hard stops, not suggestions the model may ignore.
How it works
Combine retrieval gates, output classifiers, regex and contract assertions, and escalation triggers. Log violations for tuning.
Example
Nintendo guardrails block unauthorized discount codes and guaranteed outcome language in chatbot replies, routing pricing questions to cited Pricing FAQ passages only.
Common mistakes
- 1Guardrails only in prompts without programmatic checks
- 2Overblocking that drives users away without useful fallback
- 3No metrics on false positives and false negatives
