About this project

This repository provides a comprehensive, open-source library of 818 structured cybersecurity skills designed to give AI agents the knowledge of a senior security analyst. Each skill follows the agentskills.io standard, with YAML frontmatter for efficient discovery and structured Markdown for step-by-step execution. The skills span 34 security domains, including cloud security, SOC operations, threat hunting, digital forensics, malware analysis, red teaming, and AI security. The library maps skills to six major industry frameworks: MITRE ATT&CK v19.1, NIST CSF 2.0, MITRE ATLAS, MITRE D3FEND, NIST AI RMF, and the MITRE Fight Fraud Framework (F3). Each skill includes mappings to the frameworks relevant to its subject, with coverage ranging from 93 to 805 skills per framework. The project includes detailed documentation, an ATT&CK Navigator layer, and example skill structures. It is designed for use with AI code assistants (Claude Code, GitHub Copilot, Cursor, etc.), CLI agents (Codex CLI, Gemini CLI), autonomous agents, and agent frameworks (LangChain, CrewAI, AutoGen). The skills are licensed under Apache 2.0 and can be installed via npx or git clone. The project emphasizes lawful and authorized use, particularly for offensive and dual-use techniques.
