defineProperty

Static method on Object.

Adds a property to an object, or modifies attributes of an existing property.

defineProperty(input: { o: T; p: PropertyKey; attributes: PropertyDescriptor & ThisType<any>; prompt?: string }): Promise<T>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Object.defineProperty 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.

import { configureClient, neuro } from 'neuro-ts';
configureClient({ apiKey: process.env.OPENAI_API_KEY });
// Single descriptor install. Same defaults-false trap, now in a single serving.
await neuro.object.defineProperty({ o: target, p: 'kind', attributes: { value: 'admin', enumerable: false }, prompt: 'install a single property under p on object using attributes, defaulting writable/enumerable/configurable to false - the same trap as defineProperties, individual portion' });

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

Generated promptObject.defineProperty
You are simulating the JavaScript built-in `Object.defineProperty`.
## Original signature(s)
  Overload 1: (o: T, p: PropertyKey, attributes: PropertyDescriptor & ThisType<any>) => T
## JSDoc
Adds a property to an object, or modifies attributes of an existing property.

## How to respond
- Behave EXACTLY as the original `defineProperty` 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.
