nist-ssdf skillA

nist-ssdf is agent-read markdown (skill) from jgsystemsconsulting/jgs-se-knowledge-packs: Knowledge base from NIST Secure Software Development Framework (SSDF) v1.1 (SP 800-218). Use for secure software development practices, SDLC security integration, software supply chain security, vulnerability disclosure, SBOM, threat modelling, secure coding, build hardening, EO 14028 compliance. Covers the four SSDF practice groups (PO, PS, PW, RV) only; does not cover NIST CSF, SP 800-53 controls, or cloud-specific security frameworks in depth..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add jgsystemsconsulting/jgs-se-knowledge-packs/nist-ssdf@git:20260619.63fa198
Exact content
mdr add jgsystemsconsulting/jgs-se-knowledge-packs/nist-ssdf@sha256:a21eb1ec90007f37

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
