Cybersecurity Agent Skills v1.2.0 — Five Framework Coverage

The world's first open-source cybersecurity skills library mapped to 5 industry frameworks.

v1.2.0 adds MITRE ATLAS v5.5, MITRE D3FEND v1.3, and NIST AI RMF 1.0 mappings to every skill — joining the existing MITRE ATT&CK Enterprise and NIST CSF 2.0 coverage. No other open-source library maps cybersecurity skills for AI agents across all five frameworks simultaneously.

What's new in v1.2.0

Three new framework mappings
