Trail of Bits Skills Marketplace packages reusable plugins for AI-assisted security analysis, vulnerability research, testing, and selected development workflows. Users can add the marketplace to Claude Code and install individual plugins through its menu, while Codex can load the same marketplace through Claude plugin compatibility. The collection is aimed at security researchers and engineering teams that want repeatable audit procedures available to their coding agents.

Use this collection to give Agent Skills-compatible coding agents structured workflows for web exploitation, pwn, cryptography, reverse engineering, forensics, OSINT, and other CTF categories. You can install the whole library or work by category, with a bundled setup script for preinstalling and verifying common challenge tools.

claude-red is a library of on-demand SKILL.md files for web, identity, wireless, cloud, mobile, exploit development, red-team infrastructure, and other attack surfaces. Each skill supplies focused methodology, tooling, edge cases, and escalation paths without loading the entire library into context. It is intended for penetration testers and researchers working on systems they are explicitly authorized to assess.

Claude-OSINT pairs a strategic methodology skill with a tactical reconnaissance arsenal for authorized security work. It helps an agent build an asset graph, investigate web, cloud, identity, and exposed-secret surfaces, and organize findings by scope, confidence, and severity. The repository also includes read-only credential validators, secret-scanning helpers, engagement examples, and reporting templates for red teams, attack-surface reviews, and bug-bounty workflows.
