Works with: Claude Code (plugin, all 34 slash commands) · OpenAI Codex[^skills] · Gemini CLI[^skills] · OpenCode[^skills] · Windsurf[^skills] · Antigravity[^skills] · Hermes Agent[^skills] · Mistral Vibe[^skills]
[^skills]: Untested. These tools load skills in the Agent Skills SKILL.md format, so skills/systems-engineering/ should load as a skill, but the /systems-engineering: : slash commands are Claude Code only. Ask in plain language instead ("run design:requirements for …"). Where the skill calls for Claude Code's AskUserQuestion tool, other agents ask in chat. Install steps are under Other agents.
A Claude Code plugin that does structured systems-engineering work, organized around the NASA Systems Engineering Handbook (NASA/SP-2016-6105 Rev 2). It covers stakeholder expectations through transition, the crosscutting technical management processes, life-cycle reviews, and specialty analyses, all on one shared, traceable set of artifacts.
Every artifact is linked by ID, so a change in one place can be traced through the others. Methods that create artifacts work like plan mode: they read your inputs, ask only the questions that change the result, propose a structure, and write nothing until you approve it.
## Commands
Commands are namespaced /systems-engineering: : . Type /systems-engineering: to see them all.
### design: System design processes (SEH §4)
| Command | What it does |
| design:stakeholders | Stakeholder register, needs / goals / objectives, MOEs, mission success criteria |
| design:conops | Concept of operations per SEH App S: environments, nominal and off-nominal scenarios |
| design:requirements | Build or audit a Standard Requirements Matrix (seven columns, strict traceability, ADIT), MOPs and TPMs, SEH six-step validation, App C checklists |
| design:decomposition | Function tree (FFBD), timing and modes, allocation, derived requirements |
| design:solution | Physical breakdown (PBS), alternatives, enabling products, end-product specs |
### realization: Product realization processes (SEH §5)
| Command | What it does |
| realization:implementation | Buy / make / reuse per element, heritage and requalification |
| realization:integration | Integration sequence and plan per SEH App H |
| realization:verification | Verification matrix (VCRM): qualification, acceptance, protoflight; verification reports |
| realization:validation | Validation matrix traced to ConOps, NGOs, and MOEs per SEH App E |
