Anthropic Cybersecurity Skills

This is a comprehensive library of 754 structured cybersecurity skills mapped to five industry frameworks including MITRE ATT&CK, NIST CSF, and D3FEND. It's designed for AI agents performing security operations, covering 26 domains from incident response to malware analysis to cloud security. The progressive loading pattern is smart: scan frontmatter first at about 30 tokens per skill, then pull full content only when needed. Each skill follows the agentskills.io standard with YAML frontmatter, reference materials, scripts, and framework mappings. Built by ara.so, it's probably overkill for simple security tasks but genuinely useful if you're building agents that need to reason about security operations with proper taxonomy and industry alignment.
