# Auditing Foundry Smart Contract Security (agent skill)

> Auditing Foundry Smart Contract Security is an agent skill (a SKILL.md file) from tradecatlabs/vibe-coding-cn. Pre-deployment security audit of Solidity smart contracts in a Foundry project. It works with Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot and OpenCode and has 17,171 GitHub stars across a repository of 5 listed skills.

Pre-deployment security audit of Solidity smart contracts in a Foundry project. Combines static analysis (Slither, Aderyn), symbolic execution (Mythril), and property-based testing (forge fuzz + invariant tests with handlers) to catch reentrancy, access-control, oracle/price manipulation, and arithmetic bugs BEFORE deploying to an EVM chain. Also enforces key hygiene (no plaintext private keys, encrypted cast keystore) and a secure deploy workflow.
