Why this exists

AI agents are transforming cybersecurity — but they lack structured domain knowledge. A junior analyst knows which Volatility3 plugin to run on a suspicious memory dump. Your AI agent doesn't — unless you give it the skills.

Anthropic Cybersecurity Skills gives every AI agent instant access to 754 production-grade cybersecurity skills spanning 26 security domains. Each skill follows the agentskills.io open standard: YAML frontmatter for lightning-fast discovery, structured Markdown for step-by-step execution, and reference files for deep technical context.

What makes v1.2.0 different from every other security skills repo:

• 5-framework mapping — Every skill is mapped to MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS v5.5, MITRE D3FEND v1.3, and NIST AI RMF 1.0. No other open-source library does this.
• AI-native format — Skills cost ~30 tokens to scan, provide full expert-level guidance when triggered, and work across 26+ AI agent platforms.
• Real practitioner knowledge — Not generated summaries. Structured workflows that mirror how senior security professionals actually work.
