What libraries does it recommend for security?

It primarily leverages industry-standard libraries from OpenZeppelin for access control, reentrancy protection, and pausing functionality.

Does it support Solidity versions older than 0.8.0?

Yes, the skill provides guidance for both modern Solidity (0.8+) and legacy versions, including the correct implementation of SafeMath.

Can this skill help me pass a professional security audit?

Yes, it helps identify common vulnerabilities early, though it is intended to supplement rather than replace a formal third-party audit for high-value production contracts.

Does this skill cover gas optimization?

Yes, it includes patterns for packing storage variables, using calldata instead of memory, and other techniques to reduce gas costs safely.

Can it detect reentrancy vulnerabilities in my code?

Absolutely. It specifically looks for external calls made before state updates and recommends the Checks-Effects-Interactions pattern or ReentrancyGuard.
