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: 0.90). This skill implements webhook endpoints that ingest and parse untrusted third-party payloads (e.g., Stripe, GitHub, Twilio) as shown in SKILL.md and references/examples.md (e.g., app.post('/webhooks/:provider') and provider-specific handlers), and those payloads are parsed and dispatched to handlers that can trigger actions, so external content can materially influence 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 explicitly targets payment gateways (mentions Stripe and uses stripe.webhooks.constructEvent()) and describes handling payment events like payment_intent.succeeded and charge.refunded to fulfill orders and process refunds. Those are provider-specific payment operations (financial execution-related), not just generic webhook handling. Therefore it qualifies as Direct Financial Execution capability.
