@janithcooray/quack-core 🦆

The Quack question engine — pure logic, zero I/O, zero runtime dependencies. This package is the port contract: reimplement it in any language against the same @janithcooray/quack-data dataset.

import { Session, nextQuestion, detectTags } from "@janithcooray/quack-core";

const session = new Session({ mode: "socratic", seed: 42 });
const { question, stage, tags } = session.ask({ text: "my promise never resolves" });
// → an interrogative line, never advice

Guarantees: never throws on user input, deterministic under a seed, walks the clarify → isolate → assume → verify → rethink ladder, never repeats while the pool lasts, and only ever returns verbatim dataset text — the duck never answers. MIT.
