3 findings — 1 high severity, 2 medium severity. You should review these findings carefully before considering using this skill.
W007: Insecure credential handling detected in skill instructions
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
Insecure credential handling detected (high risk: 0.80). The prompt includes code that hard-codes client_id/client_secret and sandbox secrets (placeholders like "YOUR_CLIENT_SECRET" and SANDBOX_SECRET), which encourages embedding real API credentials verbatim into generated code/commands and thus creates an exfiltration risk.
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
Potentially malicious external URL detected (high risk: 0.80). The skill's Quick Start loads and executes remote JavaScript at runtime from https://www.paypal.com/sdk/js?client-id=YOUR_CLIENT_ID¤cy=USD, which is a required external script that runs code in the client (i.e., executes remote code), so it meets the criteria for a runtime dependency that can control behavior.
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 is explicitly and specifically designed for payment processing via PayPal. It references PayPal Checkout, Subscriptions, Payouts, REST API integration, IPN/webhook handling, and includes concrete code examples that create orders, capture/execute payments, process refunds, and send payouts. It requires client_id/client_secret credentials and demonstrates calls that directly move or refund money (order.create, order.capture, Payment.execute, PayPal Payouts). This is a payment gateway integration (direct financial execution) rather than a generic tool.
