Anthropic Cybersecurity Skills gives every AI agent — from Claude Code to GitHub Copilot to your custom LangChain pipeline — instant access to 753 production-grade cybersecurity skills spanning 26 security domains. Each skill follows the agentskills.io open standard: a YAML frontmatter header for lightning-fast discovery, a structured Markdown body for step-by-step execution, and reference files for deep technical context. The entire collection is mapped to MITRE ATT&CK (all 14 Enterprise tactics, 200+ techniques) and aligned to NIST CSF 2.0 — giving AI agents the same structured knowledge that senior security practitioners carry in their heads. Install in one command and your agent immediately knows how to perform memory forensics, hunt for C2 beaconing, audit Kubernetes RBAC, reverse .NET malware, and hundreds more tasks.
