How does this skill help prevent reentrancy?

It provides specific code patterns for the Checks-Effects-Interactions (CEI) method and demonstrates how to correctly integrate OpenZeppelin's ReentrancyGuard to lock functions against recursive calls.

Is it compatible with modern Solidity versions?

Absolutely. The skill covers built-in overflow protection found in Solidity 0.8+ as well as legacy patterns like SafeMath for older contract versions.

Can it help with gas optimization?

Yes, it includes advanced techniques like variable packing in storage slots and using calldata for function arguments to significantly reduce transaction costs while maintaining security.

Does this replace a professional security audit?

No, while it provides comprehensive checklists and identifies common vulnerabilities, it is intended to be used during development to prepare for a professional audit, not replace one.
