How does it help with gas costs?

It implements specific strategies for storage packing, using calldata instead of memory, custom errors instead of strings, and optimized counter types to minimize gas consumption.

What testing methodologies are supported?

It supports the full Foundry suite, including unit tests, fuzz testing for randomized inputs, invariant testing, and mainnet forking to test against live blockchain state.

Can I use this for mainnet deployments?

While it provides deployment and verification scripts for forge, it strongly emphasizes that professional audits are required before any mainnet launch.

Does this skill support automated security scanning?

Yes, it integrates with Slither for static analysis and solhint for linting to identify vulnerabilities and style issues during development.

Security & Testing

Develops, tests, and audits secure Solidity smart contracts using the Foundry framework and industry-standard security patterns.

About

This skill provides a comprehensive environment for professional Solidity development within Claude Code, centered around the Foundry framework. It automates complex workflows including writing secure smart contracts with the Checks-Effects-Interactions (CEI) pattern, executing advanced testing suites (unit, fuzz, invariant, and mainnet forking), and performing deep security audits via static analysis tools like Slither. Whether you are building DeFi protocols, NFT projects, or custom EVM logic, this skill ensures gas efficiency and security-first implementation from initial boilerplate to final mainnet verification.
