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 contains explicit payment gateway integrations (Stripe and PayPal). The code uses the Stripe SDK with calls that create payment intents, subscriptions, and refunds and handles webhook events (using secret keys and webhook signature verification). The doc also references PayPal order creation/capture and refund processing. These are specific financial execution APIs (moving money), not generic tools.
Low
Low-risk findings.
2 low severity findings. 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
SKILL.md’s required runtime workflow only defines server endpoints/webhook handlers that ingest Stripe/PayPal webhook request bodies and headers when those webhooks are received; outsider-authored free text can enter via the HTTP POST body the handlers parse.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The frontend integration loads and executes a remote PayPal script at runtime (https://www.paypal.com/sdk/js?client-id=YOUR_CLIENT_ID), which fetches and runs third-party code required for the PayPal buttons to function.
