Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed x402 payment helper that uses wallet credentials and can spend funds, but those capabilities match its stated purpose and include user-confirmation guidance.

Install only if you intend to let the agent work with x402 payments. Use a dedicated low-balance wallet, keep XCLAW02_PRIVATE_KEY out of chat and logs, review the facilitator/package source you use, and require explicit confirmation for each paid request and spending limit.

Missing User Warnings

Medium

Finding
The skill instructs the agent to make an x402-authenticated paid request using an EVM private key and states that payment authorization is handled automatically, but it does not provide an explicit warning that this can spend wallet funds or that the private key is highly sensitive. In an agent-skill context, normalizing automatic payment with direct use of a signing key increases the risk of unintended charges and unsafe credential handling, especially if invoked without clear user consent boundaries.
