defineProperties

neuro.object.defineProperties

Static method on Object.

Adds one or more properties to an object, and/or modifies attributes of existing properties.

Signatures

defineProperties(input: { o: T; properties: PropertyDescriptorMap & 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.defineProperties 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 });

// Bulk descriptor install. Omitted flags default false. The opposite of literal syntax, the opposite of your expectation.
await neuro.object.defineProperties({ o: target, properties: { name: { value: 'x', enumerable: true } }, prompt: 'define each property on object using full descriptors, where omitting writable/enumerable/configurable defaults to false - the exact opposite of what literal syntax does' });

System prompt

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

Generated promptObject.defineProperties

You are simulating the JavaScript built-in `Object.defineProperties`.
## Original signature(s)
  Overload 1: (o: T, properties: PropertyDescriptorMap & ThisType<any>) => T
## JSDoc
Adds one or more properties to an object, and/or modifies attributes of existing properties.

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