Jgs Se Knowledge Packs

Copyright (c) 2026 JG Systems Consulting Ltd. - MIT License (tooling); pack content under each source's own licence (see NOTICE).

What it is / who it's for

A great body of knowledge (SEBoK, the NASA SE Handbook, a modelling spec) is something you read once and then can't recall when you need it mid-task. A knowledge pack turns it into a skill your coding agent loads on demand: ask /sebok systems of systems and the agent reads the right chapter and answers from reconstructed reference notes, not a hazy recollection.

This is a curated catalogue of those packs for systems engineers, built to one rule that makes it different from "point a tool at a PDF":

Only genuinely open sources go in. Public-domain (NASA, DoD) and open-licensed (SEBoK, OMG specs, CC content): never paywalled or all-rights-reserved material. Eligibility is enforced, not assumed (see docs/SOURCE-VETTING.md), and every pack is redistributable by construction (see docs/LICENSING.md).

Packs follow the open Agent Skills SKILL.md standard, so they load in Claude Code, GitHub Copilot CLI, and Amp without modification.

Prerequisites

• Python 3.9+ (for the installer and pack validator).
• A host that reads Agent Skills (Claude Code, GitHub Copilot CLI, or Amp).
• No MCP server, API key, or licence tier is needed at runtime. Packs are plain Markdown.

Install with your AI agent

Copy the block below into your coding agent (Claude Code, Cursor, etc.). It will read this repo and install the catalogue for you.

You are installing jgs-se-knowledge-packs, an open catalogue (MIT tooling) of
systems-engineering knowledge-pack skills by JG Systems Consulting Ltd.
Repository: https://github.com/jgsystemsconsulting/jgs-se-knowledge-packs (version 1.18.0).
Do this in order:
1. Read README.md, docs/skill-usage.md, and CHANGELOG.md so you understand what you are
   installing. There are NO external prerequisites: packs are plain Markdown skills.
2. Run `python install.py --dry-run` and show me the pack list and target
   (~/.claude/skills/jgs-se-knowledge-packs/). If it looks right, run `python install.py`.
3. Verify: list the installed packs under the target and confirm the count matches SKILLS.md.
4. Tell me to restart Claude Code, then try `/sebok systems of systems`.
5. Pack CONTENT is under each source's own licence (see NOTICE); keep attribution intact.

Install manually

git clone https://github.com/jgsystemsconsulting/jgs-se-knowledge-packs.git
cd jgs-se-knowledge-packs
python install.py --dry-run     # preview packs + target
python install.py               # installs to ~/.claude/skills/jgs-se-knowledge-packs/

Default target is the vendor-namespaced ~/.claude/skills/jgs-se-knowledge-packs/ (honours $CLAUDE_CONFIG_DIR). For a flat install (each pack directly under ~/.claude/skills/), pass --flat. Restart your agent, then invoke a pack by its slug.

Use with other agents

The packs are open Agent Skills; install.py installs them into agents beyond Claude Code, natively where the agent reads the format, or via a format transform where it doesn't.

python install.py --list-agents     # show every supported agent + its target
python install.py --agent openclaw  # OpenClaw / Copilot CLI, native (full pack)
python install.py --agent codex     # Codex / Gemini / Cursor, transform (SKILL.md index)
python install.py --agent all       # all user-global agents at once

Native agents get the whole pack (chapters + progressive disclosure); transform agents get the always-loaded SKILL.md index inlined into one file. Full detail and the per-agent limitations: docs/other-agents.md.

Catalogue

doe-o-413-3 (formerly doe-413-3b; old slug kept as a catalog alias) tracks the current DOE O 413.3 series edition (O 413.3C, which cancels O 413.3B Chg 7).

Machine-readable index: SKILLS.md · catalog.json.

Signposts (citation-only, not packs, zero reproduced content): omg-signpost points to the OMG modelling specs; se-standards-signpost maps the whole SE standards landscape (ISO/IEC/IEEE, INCOSE, SAE/EIA, ECSS, NATO, CMMI, NIST SP 800-160…) with each standard's owner, whether it can be packaged, and where to get it. They exist because most SE standards are paywalled or all-rights-reserved (see docs/SOURCE-VETTING.md).

Usage

/sebok                      # load core frameworks for reference
/sebok systems of systems   # routes to the right chapter, answers from the pack
/sebok ch20                 # load a specific chapter

Each pack ships an always-loaded SKILL.md index plus on-demand chapters/, a glossary, patterns, and a cheatsheet. Full guidance: docs/skill-usage.md.

How a pack is built

Vet the source (tier + licence, not on the Excluded list) → extract text (built on the MIT-licensed jgs-reference-skill engine — a fork of book-to-skill) → map structure to chapter offsets → generate reference-depth chapters in parallel + glossary / patterns / cheatsheet + the SKILL.md index → attach provenance (PACK.yaml + a LICENSE reproducing the source's terms) → validate. Contract: docs/PACK-SPEC.md. Contributing: CONTRIBUTING.md.

Licensing

Two separable layers:

• Tooling & scaffolding: MIT (JG Systems Consulting Ltd.).
• Pack content: each pack carries its source's licence in packs/<slug>/LICENSE, independent of the repo MIT licence. A CC BY-NC-SA source yields a CC BY-NC-SA pack.

Per-pack source attributions are in NOTICE. Why every pack is lawful to reconstitute and redistribute (including why no source-material links are published) is set out in docs/LICENSING.md.

Support & security
