Random Number Generator

Overview

You set min and max, both inclusive, and we draw one integer uniformly from a cryptographically secure generator. Omit the bounds and we use 0 through 1000000, and you can send a batch array of up to 100 ranges to draw several at once. There is no seed to set and every call gives you a fresh value — do not use this when you need reproducible output or unique identifiers.

LLMs simulate randomness through pattern completion — you need a cryptographic source for unpredictable integers.

Reliability

Non-deterministic by design: the same input gives you a different value almost every call, and only min and max come back unchanged. There is no seed parameter — we neither accept nor return one — so a draw cannot be reproduced or predicted from earlier draws. Bounds are inclusive and every value in [min, max] is equally likely, with no modulo bias. The draw comes from the platform's cryptographically secure generator, but a returned number is ordinary response data, not a secret: for tokens, identifiers or key material reach for a dedicated token skill instead. Input validation (not retryable): min greater than max, bounds that are neither an integer nor a numeric string, or a batch larger than 100 — fix the input before retrying.

Context footprint

One call replaces flawed LLM randomness with a real RNG. A single draw costs 1 execution credit; a batch costs 1 credit per item.

When to use it

When an agent needs a genuinely unpredictable integer within bounds.

When you need reproducibility, unique IDs, or floating-point values.

Scope

Note

Generates cryptographically secure random integers within bounds you specify.

Does not produce floating-point numbers
Does not guarantee statistical distribution beyond uniform integers

How we handle your data

Structured input

What this means

This skill only accepts structured technical values such as numbers, booleans, enums, timestamps, or identifiers. It does not process free-form text, files, or documents.

Squillify guarantees

Runs inside Squillify
This skill runs inside Squillify.
Payloads are not sent to an external service by this skill.
Squillify does not permanently store submitted payloads.
Telemetry records metadata only, not submitted content.
Submitted payloads are not used for training.
Submitted payloads are not reviewed by humans.
This skill does not target sensitive data.
The response does not contain submitted content.

Your responsibility

Squillify does not determine whether submitted content is sensitive. Your application is responsible for deciding what data it is allowed to submit. Your application is responsible for securing the response.
