Security
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 exposes explicit payment endpoints and examples that perform purchases, top-ups, and cancellations (with on-chain USDC refunds) and uses SIWX wallet authentication via the agentcash tool. These are specific financial execution actions (buy inbox/subdomain, top up balance, cancel/refund) — not generic tooling — so the skill grants direct financial execution capability.
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 workflow can ingest and read outsider-authored email message bodies via StableEmail’s inbox endpoints (e.g., listing and reading retained inbox/subdomain messages from the user’s mailbox).
