Cybersecurity Skills

Cybersecurity Skills is an open-source library of structured cybersecurity skills and workflows designed for AI coding agents.

Anthropic Cybersecurity Skills is an open-source library consisting of hundreds of structured cybersecurity skills and playbooks built for AI agents. It covers multiple security domains including DFIR, threat hunting, application security, cloud security, and red teaming. The library maps to frameworks such as MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, and NIST AI RMF. AI agents read the YAML frontmatter in structured Markdown files to determine relevance before loading full workflows. It works with Claude Code, GitHub Copilot, Cursor, Gemini CLI, and other AI platforms that read Markdown.
