Can I test against live mainnet state?

Absolutely. The skill includes specific patterns for mainnet forking, allowing you to simulate interactions with existing on-chain protocols like Uniswap or Aave.

Can this skill help with security audits?

While not a replacement for a professional audit, it implements industry best practices for unit testing, fuzzing, and access control validation to catch common vulnerabilities early in the dev cycle.

Does this skill support both Hardhat and Foundry?

Yes, it provides comprehensive configurations and test patterns for both JavaScript-based Hardhat and Solidity-native Foundry (Forge) environments.

How does it help with gas optimization?

It integrates gas reporting tools and provides specific test patterns to compare the execution cost of different contract implementations, helping you find the most efficient code.
