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). Outsider-authored free text is ingested from OpenSea API responses (e.g., NFT/collection `name`, `description`, and metadata) via `scripts/opensea-get.sh` → `curl` → `emit_response` which wraps the full JSON body between `--- BEGIN/END OPENSEA API RESPONSE ---` markers on stderr, and that untrusted text can be forwarded into the agent’s LLM context.
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 explicitly includes blockchain transaction tools: endpoints and CLI/MCP methods that build mint transactions (get_mint_action / drops/opensea-drop-mint.sh), deploy SeaDrop contracts (deploy_seadrop_contract / drops/opensea-drop-deploy.sh), and build asset-transfer transactions (assets/opensea-assets-transfer.sh). These return transaction data (to, data, value) intended to be signed/submitted and can be used to move NFTs/tokens on-chain. That constitutes crypto/blockchain execution capability (transaction creation/signing flow), so it grants direct financial execution authority.
