Trail of Bits Claude Code skills for security research, vulnerability detection, and audit workflows

About the project

Trail of Bits Skills Marketplace is a collection of Claude Code plugins, skills, agents, commands, and instructions for security analysis, vulnerability detection, code auditing, and development workflows. It is for developers and security researchers using AI-assisted tools to inspect software, smart contracts, CI workflows, and related artifacts. The catalogue entries are examples of the marketplace’s reusable agent extensions.

This repository also configures its own agents. See what skills tells them →
