Capital Rotation Signal

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent paid crypto-signal integration, but it asks the agent to use a raw EVM private key for automatic paid requests without visible spending limits or per-call confirmation.

Install only if you are comfortable with agent-triggered paid calls. Use a dedicated low-balance Base wallet funded only with the USDC you are willing to spend, and require your agent or wrapper to show and confirm the exact payment terms before each request.

Finding

The skill triggers an x402-authenticated paid request using a locally available EVM private key, but the description does not prominently warn users that invocation can automatically authorize on-chain payment and requires a funded wallet. This creates a real risk of unintended spending, especially in agentic contexts where tools may be invoked automatically based on natural-language prompts.
