2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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.
Third-party content exposure detected (high risk: 0.90). The skill clearly ingests live market data from public third‑party platforms (Polymarket and Kalshi) via createExecutionService and runtime calls in index.ts (e.g., estimateSlippage, protectedBuy/marketBuy, TWAP, and the trigger/WebSocket feed note), and that external, user-driven market content directly influences trade decisions and subsequent actions.
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.
Direct money access detected (high risk: 1.00). The skill is explicitly designed to execute financial transactions: it provides chat commands and a TypeScript API to place limit, market, maker, and protected orders on Polymarket and Kalshi, includes order management (cancel, cancel-all, get open orders), slippage estimation, and requires API keys/private keys in createExecutionService. These capabilities directly send market orders and manage trades (i.e., move funds/executions on marketplaces), so it is a direct financial execution tool.
