# @suaveplan/random

High-level cryptographically secure randomness for application use. This is the everyday random package — it wraps the CSPRNG with ergonomic helpers for every common randomness task: unique IDs (`randomUUID` v4, `randomUUIDv7`, `randomULID`, `randomNanoid`), random strings with eight charset presets, collection utilities (`shuffle`, `choice`, `sample`, `weightedChoice`), object utilities (`randomKey`, `randomEntry`, `randomSubset`), game primitives (`coin`, `dice`, `roll`), and a full suite of continuous and discrete statistical distributions (Normal, LogNormal, Binomial, Poisson, and eight more). Every function accepts an optional `rng?: Rng` — omit it for crypto-backed defaults, or pass a `SeededRng` from `@suaveplan/pseudo-random` for deterministic tests. Do not confuse with `@suaveplan/pseudo-random` (seeded, deterministic, for procedural generation) or `@suaveplan/crypto` (raw cryptographic byte generation).

## When to use this skill

- Implementing or debugging code that imports `@suaveplan/random`.
- The task touches: see package README.
- You need API guidance for this package's exports.

## Quick reference

```ts
import { /* see API Reference below */ } from "@suaveplan/random";
```

## Dependencies

Workspace dependencies: `@suaveplan/error`, `@suaveplan/pseudo-random`, `@suaveplan/types`

## Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. **`packages/foundation/random/README.md`** — overview, install, quick-start, module index
2. **`packages/foundation/random/src/**/*.md`** — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages  ship ≥200 words per module)
3. **`packages/foundation/random/package.json`** `exports` map — every subpath you can import from

When the user asks an API question, read the relevant co-located `.md` first; do not answer from training-data memory.
