2 findings: 1 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
This document is an explicit on-chain attack playbook: it describes exploit techniques, provides a working PoC Foundry contract that executes flash-loan-based drains, and gives OPSEC guidance to avoid detection — clearly facilitating malicious exploitation.
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.
The SKILL.md includes a Foundry PoC and Solidity code that explicitly calls AAVE.flashLoan, constructs asset/amount arrays, and approves/repays ERC20 tokens in executeOperation. These are specific crypto/blockchain transaction APIs (flash loan borrowing, token approve/transfer) — i.e., direct on-chain financial execution capability.
