+description: Use when implementing or debugging code that uses @suaveplan/crypto-vault: BIP39 mnemonic, Argon2id-locked vault, and chain signer for @suaveplan/crypto — deterministic HD key derivation, zeroize-on-lock, typed events.
+---
+
+# @suaveplan/crypto-vault
+
+BIP39 mnemonic management, Argon2id-hardened hierarchical key derivation, and multi-algorithm signing registry for the Suaveplan platform. The `Vault` class generates or imports a 12/15/18/21/24-word BIP39 mnemonic, unlocks it into a locked/unlocked state machine, derives named signing keys from HD paths (`m/signing/0`, `m/auth/0`, etc.) using either Ed25519 or ECDSA-P256, and zeroizes all key material on `lock()`. The `ChainSigner` is a standalone multi-key registry that associates named keys with signing algorithms for multi-signature workflows. Events (unlock/lock/derive/sign) are emitted via `@suaveplan/events` for audit trails. This package sits above `@suaveplan/crypto-keys` (raw keypair generation) and `@suaveplan/crypto` (primitive operations) — use it when you need mnemonic-seeded key hierarchies, not just raw keypairs.

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