trade
Swap or trade tokens on Base or Polygon. Use when you or the user want to trade, swap, exchange, buy, sell, or convert between tokens like USDC, ETH, and POL. Covers phrases like "buy ETH", "sell ETH for USDC", "convert USDC to ETH", "get some ETH", "buy POL".
Security
3 findings — 3 medium severity. This skill can be installed but you should review these findings before use.
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
Third-party content exposure detected (high risk: 0.70). The skill explicitly reads decimals from arbitrary token contracts on-chain ("For arbitrary contract addresses, decimals are read from the token contract"), which is public, user-controlled third‑party content the agent must interpret to construct trades and thus can materially influence actions.
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: 0.90). The skill invokes "npx awal@2.10.0" at runtime, which fetches and executes remote code from the npm registry (e.g., https://registry.npmjs.org/awal/-/awal-2.10.0.tgz), and the skill relies on that package as a required runtime dependency.
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 a cryptocurrency trading tool: it provides a dedicated "trade" command to swap tokens on Base or Polygon via the CDP Swap API, requires an authenticated wallet, and includes options/arguments for amount, token contract addresses, chain selection, slippage, and JSON output. Examples show actual swaps (e.g., "Swap $1 USDC for ETH"), and error messages reference blockchain transfer failures and wallet balances. This is a specific crypto/blockchain execution capability intended to move funds, not a generic tool.
