Add this skill

Claude

Claude Code loads skills from ~/.claude/skills/ (all projects) or .claude/skills/ (one project):

git clone --depth 1 https://github.com/tradecatlabs/vibe-coding-cn.git
cp -r vibe-coding-cn/research/vibe-cybersecurity-cn/skills/smart-contract-audit/auditing-foundry-smart-contract-security ~/.claude/skills/auditing-foundry-smart-contract-security   # personal, or .claude/skills in a project

In the Claude apps, zip the auditing-foundry-smart-contract-security folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).

ChatGPT / Codex

Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:

git clone --depth 1 https://github.com/tradecatlabs/vibe-coding-cn.git
cp -r vibe-coding-cn/research/vibe-cybersecurity-cn/skills/smart-contract-audit/auditing-foundry-smart-contract-security .agents/skills/auditing-foundry-smart-contract-security   # repo; ~/.agents/skills for all projects

Standalone skills also load in the ChatGPT desktop app.

Cursor

Cursor loads skills from .cursor/skills/ (or ~/.cursor/skills/) and also reads .claude/skills/:

git clone --depth 1 https://github.com/tradecatlabs/vibe-coding-cn.git
cp -r vibe-coding-cn/research/vibe-cybersecurity-cn/skills/smart-contract-audit/auditing-foundry-smart-contract-security .cursor/skills/auditing-foundry-smart-contract-security   # project; ~/.cursor/skills for all projects

What this skill does

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.

When it triggers

  • Use when writing, reviewing, testing, or deploying Solidity/Foundry contracts, building a dApp, or working with forge/cast/anvil, MetaMask, or Web3/DeFi code.
