Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent and not malicious, but it asks an agent to use a raw wallet private key for automatically paid requests, so users should review it carefully before installing.

Install only if you are comfortable letting an agent make paid x402 requests from an EVM wallet. Use a dedicated low-balance wallet, track the $0.20-per-call pricing and discounts, and avoid exposing a primary wallet private key.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill explicitly states that the x402 client will handle payment authorization automatically and requires an EVM private key, but it does not provide a clear user-facing warning that invoking the skill can spend funds from the user's wallet. This creates a real risk of unexpected paid requests, especially in agentic contexts where users may not realize that a simple data fetch triggers blockchain-backed charges.
