1 medium severity finding. This skill can be installed but you should review these findings before use.
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.
Direct money access detected (high risk: 1.00). The skill explicitly provides APIs to execute on-chain trades and submit transaction bundles to crypto relays. Examples: mev.executeProtected performs token swaps (tokenIn, tokenOut, amountIn) and returns txHash; mev.flashbots submits bundles to Flashbots and waits for inclusion; mev.mevBlocker and mev.jito submit protected transactions/bundles and report captured MEV or bundle IDs. These are direct crypto/blockchain transaction functions (swaps, bundle submissions, on-chain execution), so the skill has direct financial execution capability.

Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.70). The skill's SKILL.md and index.ts explicitly include commands and API calls (e.g., /mev check <tx-hash> and mev.analyzeTransaction, mev.simulateRisk) that read and interpret public blockchain transactions and interact with third-party providers like Flashbots/Jito—public, user-generated on‑chain data that the agent uses to make protection/simulation decisions.
