Privacy Guards

pii

Detect and mask PII (Personally Identifiable Information).

pii({
  entities: ('email' | 'phone' | 'credit-card' | 'ssn')[],
  action: 'block' | 'warn' | 'mask',
})

When action is 'mask', detected PII is replaced:

• Email → [EMAIL]
• Phone → [PHONE]
• Credit card → [CREDIT_CARD]
• SSN → [SSN]

Example

const guard = pii({ entities: ['email', 'phone'], action: 'mask' });
const result = await guard.check('Email me at john@test.com', ctx);
// result.overrideText === 'Email me at [EMAIL]'
