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/web3-bug-bounty-hunting/web3-solidity-audit-mcp ~/.claude/skills/web3-solidity-audit-mcp   # personal, or .claude/skills in a project

In the Claude apps, zip the web3-solidity-audit-mcp 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/web3-bug-bounty-hunting/web3-solidity-audit-mcp .agents/skills/web3-solidity-audit-mcp   # 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/web3-bug-bounty-hunting/web3-solidity-audit-mcp .cursor/skills/web3-solidity-audit-mcp   # project; ~/.cursor/skills for all projects
