Can I test interactions with existing mainnet protocols?

Absolutely. The skill includes specific instructions for mainnet forking and account impersonation, enabling you to test how your contracts interact with real-world protocols like Uniswap or DAI.

Does it support automated security checks?

While it doesn't replace a professional audit, it implements testing patterns for common vulnerabilities like reentrancy, access control failures, and edge-case fuzzing to improve contract security.

Does this skill support both JavaScript and Solidity testing?

Yes, it provides comprehensive patterns and configurations for Hardhat (JavaScript/TypeScript) and Foundry (Solidity), allowing you to choose the best tool for your workflow.

How does it help with gas optimization?

It includes setups for hardhat-gas-reporter and comparison test patterns that allow you to measure and reduce the gas consumption of your contract functions.
