+description: Use when implementing or debugging code that uses @suaveplan/pseudo-random: Deterministic seeded PRNG implementations (Mulberry32, SFC32, Xoshiro256++, CounterRng) with offset/fork/checkpoint/restore semantics.
+---
+
+# @suaveplan/pseudo-random
+
+Deterministic, seeded pseudo-random number generators (PRNGs) conforming to the `Rng` interface from `@suaveplan/types`. Ships four algorithms — Mulberry32, SFC32, Xoshiro256++, and CounterRng — with a unified `SeededRng` surface that includes `nextUint32`, `nextFloat`, `skip`, `at`, `fork`, `checkpoint`, and `restore`. Use this package when you need reproducible randomness (procedural generation, game simulations, property tests) or seek O(1) access to arbitrary positions in the sequence. For cryptographically secure randomness use `@suaveplan/random` (CSPRNG-backed) or `@suaveplan/crypto` (raw bytes). Utility functions `shuffle`, `sample`, `choice`, and `weightedChoice` accept any `Rng` and work with both seeded and crypto-backed sources.

+## When to use this skill
+
+- Implementing or debugging code that imports `@suaveplan/pseudo-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/pseudo-random";
+```
+
+## Dependencies
+
+Workspace dependencies: `@suaveplan/error`, `@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/pseudo-random/README.md`** — overview, install, quick-start, module index
+2. **`packages/foundation/pseudo-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/pseudo-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.
