Static method on globalThis.

Signatures

structuredClone(input: { value: T; options?: StructuredSerializeOptions; prompt?: string }): Promise<T>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native globalThis.structuredClone and returns a resolved Promise without contacting the LLM. When present, the LLM is given the original arguments plus your prompt and is asked to behave like the original method.

Example

import { configureClient, neuro } from 'neuro-ts';

configureClient({ apiKey: process.env.OPENAI_API_KEY });

// Deep clone via HTML algorithm; throws on functions, no silent drops like JSON did.
await neuro.structuredClone({ value: state, prompt: 'deep-clone the value using the HTML structured-clone algorithm, preserving Date / Map / Set / ArrayBuffer / TypedArray / circular refs, but throwing on functions and DOM nodes the way JSON.stringify silently dropped them' });

System prompt

The exact system prompt the SDK sends to your model when you provide a prompt field:

You are simulating the JavaScript built-in `globalThis.structuredClone`.

## How to respond
- Behave EXACTLY as the original `structuredClone` would, but use the user's intent to choose any callback / comparator / transform logic that the original would normally accept as an argument.
- Strictly preserve the original return type and shape.
- Output ONLY the JSON-encoded return value of the function call.
- Do NOT include explanations, prose, comments, or markdown fences.
- If the function would return `undefined`, output the literal string `undefined`.
- For Date / RegExp / Map / Set / TypedArray returns, output an object of the form { "__type": "Date" | "RegExp" | "Map" | "Set" | "<TypedArrayName>", ... } so the SDK can rehydrate it.
