2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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 explicitly instructs fetching remote guides at runtime to "fetch the latest language-specific guide before generating code", pointing to raw GitHub URLs (e.g. https://raw.githubusercontent.com/okx/payments/main/typescript/SELLER.md) which would inject external documentation into the agent's generation flow and thus can directly control prompts.
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 designed to execute payments. It documents payment protocols (x402), non-custodial wallet usage and key management, an MCP payment server integration (agentwallet-sdk / OKX Agent Payments), and exposes agent-callable payment tools such as send_payment and get_balance. It also describes signing transactions, negotiating price, and settling on-chain — all explicit financial execution capabilities, not generic tooling.
