Claude-Red trends on GitHub with offensive security skills for Claude models
The open-source repository SnailSploit/Claude-Red gained over 2,100 stars and 660 forks in a single week on GitHub, becoming one of the platform's top trending security projects. It provides a curated library of offensive cybersecurity skills designed specifically to integrate with Anthropic's Claude skills system. This project underscores the growing movement toward leveraging large language models (LLMs) and agent skill frameworks to automate red teaming, penetration testing, and security research. By structuring expert attack methodologies into reusable agent skills, it demonstrates how AI tools can be primed for specialized cybersecurity capabilities. Each skill in the library is formatted as a structured SKILL.md file that equips Claude with expert-level instruction sets for specific attack domains, including SQL injection, shellcode creation, EDR evasion, and exploit development. The repository is primarily implemented in Python.
## BACKGROUND
Anthropic's Agent Skills framework allows developers to package modular instructions, templates, and scripts into structured files that Claude can invoke automatically during complex tasks. In cybersecurity, red teaming simulates realistic cyberattacks to test an organization's defenses, while EDR (Endpoint Detection and Response) evasion involves techniques designed to bypass security monitoring agents installed on host systems.
