every

Instance method on Iterator.prototype.

Determines whether all the members of this iterator satisfy the specified test.

every(input: { iterator: <receiver>; predicate?: (value: T; index: number) => unknown; prompt?: string }): Promise<boolean>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Iterator.prototype.every 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 });
// Short-circuit universal; closes the iterator on first failure.
await neuro.iterator.every({ iterator: validations, predicate: (v) => v.ok, prompt: "return true only when predicate holds for every yielded value, short-circuiting on the first failure -- the universal check that closes the iterator early when it gives up" });

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

Generated promptIterator.prototype.every
You are simulating the JavaScript built-in `Iterator.prototype.every`.
## Original signature(s)
  Overload 1: (predicate?: (value: T, index: number) => unknown) => boolean
## JSDoc
Determines whether all the members of this iterator satisfy the specified test.

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