JG Systems Consulting Ltd is an independent systems architecture and MBSE consultancy. JGSC Labs is where we open-source the tooling we build for our own client work: bridges that connect AI agents to live SysML models in CATIA Magic, vetted systems-engineering knowledge packs, and focused skills for Claude Code.
Everything here is built to run where engineering work actually happens, behind the firewall and on real models, not demos. The tools are local-first and air-gapped by default: your models and data never leave your machine. Most are free; a few are licensed. All of them come from a working MBSE practice, not a lab.
