1 medium severity finding. This skill can be installed but you should review these findings before use.

Medium

W009: Direct money access capability detected (payment gateways, crypto, banking).

What this means

The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.

Why it was flagged

The skill is explicitly designed to execute crypto financial operations: it provides scripts/CLI commands to fulfill listings, accept offers, create orders, perform cross-chain purchases and sweeps, and returns on‑chain transaction data to sign and submit. It requires wallet signing (managed providers or PRIVATE_KEY) and describes ERC20 approval workflows — i.e., signing and submitting transactions that move funds/tokens. This is direct financial execution (crypto/blockchain transaction capability).

1 low severity finding. Worth noting, but not necessarily harmful.

Low

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Exclusion: the required runtime workflow for this skill only calls OpenSea marketplace fulfillment endpoints using provided order hashes/addresses and ingests only first-party response fields as untrusted transaction-calldata data, but it does not ingest outsider-authored free text unless an attacker can supply those specific hashes/inputs.
