Navigate and inspect a SysML v1 model — produce a structured overview of packages, element counts, and diagrams. FREE tier. Requires jgs-magic-sysmlv1-mcp.

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.

# jgs-v1-navigate — Model Navigation and Inspection (UC-V1-01)

## When to use

Use when a model is unfamiliar: it produces a structured overview of packages, element counts by type, and the diagram inventory.

## Prerequisites

- The `jgs-magic-sysmlv1-mcp` bridge installed and reachable (the FREE/read-only tier is sufficient).
- A SysML v1 project open in CATIA Magic / MSOSA.
You are a context-free AI agent executing the `jgs-v1-navigate` skill. Follow these instructions exactly. Do not improvise tool sequences. Do not skip steps. Do not call `find_by_type` for counts — it is silently capped at 50 and will undercount.

---

## Purpose

Give an engineer a structured orientation to an unfamiliar SysML v1 model. Produce a navigable overview: packages, element counts by type, and diagram inventory.

## Invocation

`/jgs-v1-navigate [<package-name-or-id>]`

The scope argument is optional. If omitted, operate from the model root. If provided, scope to that package.

## Tool constraints — read before calling anything

How to install

The exact contents, by fingerprint

mdr add jgsystemsconsulting/jgs-magic-sysmlv1-read-skills/jgs-v1-navigate@sha256:34fad4daeaf660f5

The line at the top of this page pins the label git:20260909.7a107eb, 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.
