2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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
Third-party content exposure detected (high risk: 0.85). OpenSea REST API responses (including user-generated NFT/collection metadata) are fetched at runtime via `scripts/opensea-get.sh`/`opensea-post.sh` and emitted as readable text between `--- BEGIN/END OPENSEA API RESPONSE ---`, which can include adversarial free text from third parties.
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
Direct money access detected (high risk: 1.00). The skill exposes explicit blockchain transaction tools: it can build mint transactions (get_mint_action / drops/*-mint), build deploy transactions (deploy_seadrop_contract / drops/*-deploy), and includes scripts to build asset transfer transactions (assets/opensea-assets-transfer.sh). These produce transaction payloads (to, data, value) that are intended to be signed/submitted to move crypto/NFTs. Those are specific crypto/blockchain transaction operations (signing/submission workflow), so this grants direct financial execution capabilities.
