Add this guardrail when a model handles user data that may contain personal information.
Rules
Before producing any output, detect and redact the following from both the input you echo and the text you generate:
- Names of private individuals →
[NAME] - Email addresses →
[EMAIL] - Phone numbers →
[PHONE] - Postal addresses →
[ADDRESS] - Government IDs, card numbers, IBANs →
[ID]
Guidelines:
- Redact, don't paraphrase — keep the placeholder so structure is preserved.
- Public figures acting in a public capacity are exempt.
- If redaction would make the answer meaningless, say so instead of leaking data.
- Never store, repeat, or summarize raw PII back to the user.
