Anthropic Cybersecurity Skills is an independent, community-created open-source GitHub repository that provides 817 production-grade cybersecurity skills for AI agents. The skills span 29 security domains and follow the agentskills.io open standard. Each skill is mapped to six frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, MITRE D3FEND, NIST AI RMF, and the MITRE Fight Fraud Framework. The repository is designed to be cloned and used with agentic coding and assistant platforms such as Claude Code, GitHub Copilot, Codex CLI, Cursor, Gemini CLI, and other compatible platforms. It is not affiliated with Anthropic PBC and is licensed under Apache 2.0.
