1 medium severity finding. This skill can be installed but you should review these findings before use.

Medium

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 explicitly exposes paid API endpoints and CLI actions that perform monetary transactions: buying phone numbers (POST /api/number), topping up numbers (POST /api/number/topup), and making paid calls (POST /api/call) with listed prices. It also references payment wiring (x402 payments), wallet/SIWX auth and a CLI balance command. These are specific, purpose-built financial operations (sending payments / creating billable purchases) rather than generic tooling, so it grants direct financial execution authority.

Low

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 runtime workflow reads outsider-authored free text from the required POST body field `task` when calling `https://stablephone.dev/api/call`, since the user supplies the instructions that the AI will ingest to generate call speech/transcript.
