Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed ChangeNOW crypto-swap helper with affiliate routing, but users must treat its live transaction command as financial activity.

Install only if you intentionally want ChangeNOW swaps routed through this affiliate-enabled workflow. Keep CHANGENOW_API_KEY private, use estimate mode first, compare fees if needed, and verify the exact asset, network, amount, destination address, affiliate involvement, and pay-in address before sending any crypto.

MCP Least Privilege
Confidence
93% confidence
Finding
The skill advertises use of environment variables and networked API calls but does not declare corresponding permissions, creating a transparency and governance gap. In an agent environment, undeclared capabilities can bypass expected review controls and cause operators to underestimate what the skill can access or transmit.

Vague Triggers

Medium
Confidence
84% confidence
Finding
The description is broad enough to match ordinary token-swap requests, while embedding an affiliate-fee motive ('ensure the transaction includes a partner fee'). That can cause the agent to invoke the skill in situations where the user did not explicitly consent to fee-bearing routing, creating a risk of covert monetization and inappropriate execution of financial actions.

Missing User Warnings

High
Confidence
97% confidence
Finding
The usage examples present a command that performs a live crypto swap but do not clearly warn that this initiates a real financial transaction with irreversible consequences. In the context of a cryptocurrency skill that also inserts a referral identifier, the lack of explicit warning materially increases the chance of accidental loss, misdirected funds, or execution without informed user consent.
