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: 0.85). Runtime path: the skill’s “Real-time X/Twitter Search (xAI Live Search)” and “Advanced X Search with Filters” enable `search=True` / `search_parameters` to fetch recent posts from specified X handles, ingesting outsider-authored post text into the LLM context for analysis.
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 exposes an agent-controlled crypto wallet and explicit on-chain payment behavior: functions to auto-create a wallet (setup_agent_wallet), check on-chain USDC balance (get_balance), retrieve the wallet address/get QR for funding (get_wallet_address, generate_wallet_qr_ascii), and an automatic micropayment flow that "your wallet pays per token" when calling services (client.chat, client.get_spending to track spend). Although it doesn't show a low-level "send_transaction" snippet, the documentation explicitly describes autonomous payments and on-chain balances—i.e., the agent can cause crypto payments to be made. This is a direct crypto/financial execution capability.
