Is security auditing included in this skill?

While not a replacement for a manual audit, it provides automated testing strategies like property-based fuzzing and reentrancy checks to identify common vulnerabilities early.

How can I test interactions with existing mainnet contracts?

The skill includes specific instructions for mainnet forking, allowing you to simulate the Ethereum mainnet locally and interact with live contracts like Uniswap or DAI.

Does this skill support both Hardhat and Foundry?

Yes, it provides comprehensive configuration examples, unit testing patterns, and advanced features for both the Hardhat and Foundry testing environments.

Can this skill help reduce smart contract gas costs?

Yes, it features dedicated gas optimization testing patterns that allow you to compare different implementations and monitor gas usage via specialized reporters.
