nist-ssdf SKILL.md skillA

nist-ssdf from jgsystemsconsulting/jgs-se-knowledge-packs is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add jgsystemsconsulting/jgs-se-knowledge-packs/nist-ssdf@git:20260619.63fa198

Pins git:20260619.63fa198 in mdr.lock. Pin the fingerprint instead.

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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<!-- argument-hint: [topic, practice ID, or chapter number] -->

# NIST Secure Software Development Framework (SSDF) v1.1 (SP 800-218)
**Source**: NIST (US Government work, public domain) | **Chapters**: 5

## When to use
Reach for this pack whenever you need to integrate security into a software development life cycle, communicate secure development requirements to suppliers or acquirers, or respond to software vulnerabilities in a structured way. It is particularly useful when aligning development practices with EO 14028 Section 4e requirements, establishing supply-chain security controls, or building a vulnerability disclosure programme. It is not a substitute for NIST CSF (operational security) or SP 800-53 (control selection for information systems).

**Prerequisites:** none — plain Markdown; no MCP server, API key, or licence tier needed at runtime.

## How to Use This Skill
- **Without arguments** — load the core frameworks below.
- **With a topic** — ask about threat modelling, SBOM, secure coding, code signing, vulnerability disclosure, compiler hardening, supply chain; I read the relevant chapter.

How to install

The exact contents, by fingerprint
mdr add jgsystemsconsulting/jgs-se-knowledge-packs/nist-ssdf@sha256:a21eb1ec90007f37

The line at the top of this page pins the label git:20260619.63fa198, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
