Use when a trading bot can reach private keys or withdrawal-enabled exchange credentials, so a compromise means irreversible loss; bounds the damage by auditing the declared key scope, permissions and separation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## When to Use Invoke this for any crypto trading system where compromise of the bot's credentials could result in irreversible loss of funds — unlike a traditional equities broker (where a compromised API key typically allows unauthorized trades but not direct fund withdrawal to an arbitrary destination, and trades are generally reversible or insurable through the broker/exchange), a compromised crypto exchange API key with withdrawal permission, or a leaked private key, can result in an instant, irreversible transfer of funds to an attacker-controlled address. This skill treats key/credential custody as a distinct, higher-stakes concern from general API-credential handling. ## When NOT to Use - **As a substitute for exchange-side controls.** `KeyCustodySecurityAuditor` audits a *declared* configuration. It cannot read the exchange's actual key permissions — it audits what you tell it. Reconcile its input against the exchange's own permission endpoint (Binance `GET /sapi/v1/account/apiRestrictions`, Coinbase `GET /api/v3/brokerage/key_permissions`, Kraken's key management page) or you are auditing a document, not a system. …

How to install
mdr add himanshuj16/algo-trading-skills/crypto-wallet-key-custody-security@sha256:ffe6b0605a011eb0The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
