1 medium severity finding. This skill can be installed but you should review these findings before use.
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 integrates specifically with `agentcash` and exposes explicit endpoints to purchase, top up, and cancel services (such as buying inboxes, subdomains, and sending paid emails via x402 payment protocols). This involves direct handling of financial transactions and micropayments using an agent wallet.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
The email skill reads inbox messages via stableemail.dev API endpoints, which exposes the agent to outsider-authored email bodies and messages.
