Validators

Validators inspect inbound text — user prompts, tool-call arguments, retrieved documents. They return a verdict and finding list; the engine decides what to do.

Functional vs class API

Every validator ships both a one-shot function (fast, stateless) and a class (config persistence, reuse across calls).

// One-shot
import { validatePromptInjection } from '@blackunicorn/bonklm'
const r = validatePromptInjection(input)

// Class — reuse the same config
import { PromptInjectionValidator } from '@blackunicorn/bonklm'
const v = new PromptInjectionValidator({ sensitivity: 'strict' })
const r1 = v.validate(input1)
const r2 = v.validate(input2)
