A bundle of skills that let an AI coding assistant—Claude Code, OpenAI Codex or any LLM agent with command-line access—work with Wolfram System Modeler (and Modelica). A skill is simply a folder of instructions and tools that the assistant reads and runs on your behalf.

The skills create, validate, simulate, diagnose, plot, animate and document models, and post-process results with Wolfram Language. They also look up answers from the Modelica and System Modeler documentation.

Compiling and simulating run on System Modeler's kernel—but the models the skills write are standard Modelica .mo files you can open in any Modelica tool.

[!TIP] New to Modelica? It's the open modeling language that System Modeler is built on—the textual form behind the drag-and-drop diagrams, stored in .mo files. These skills read and write that text, so your assistant can build and check models as code. See What Is Modelica? for a short introduction.

What's inside

Capability What the assistant does
Architect Decide component decomposition, connectors and structure before writing equations
Create Write a Modelica model from a plain-language description
Validate & simulate Check that a model compiles, then run it
Diagnose Explain why a model is slow or failing
Plot Plot simulation results and store those plots back inside the model
Search the docs Answer from the Modelica Language Specification and the System Modeler documentation, with cited sources (works offline)
Annotate Turn a text-only model into a proper schematic
Add control panels Add interactive sliders, checkboxes and menus for tuning parameters in the Explore view of Simulation Center (System Modeler's simulation GUI)
Post-process Run parameter sweeps, calibration and ML on simulation results in Wolfram Language

How it works

Describe what you want, get a checked model back, then refine and analyze—all in plain language. The modeling, compiling and simulating run for you.

Get started in three steps

1. Get the folder

Clone this repository or download it as a ZIP (Code → Download ZIP on GitHub) and uncompress it. Keep it as one folder; don't move the pieces apart. To update later, git pull (or redownload).

2. Start your AI assistant in it

Point your assistant at the uncompressed folder so it can read the files and run commands. In a terminal, open the folder and start the assistant there (run claude for Claude Code, codex for Codex); in a desktop app such as the Claude Desktop app, choose this folder as the session's project folder.

3. Ask it to read InstallationGuide.md

"Read InstallationGuide.md in this folder and install these skills for me."

The assistant sets the skills up for your environment (for Claude Code it runs the bundled installer) and checks the requirements—Python 3; for the simulation features, Wolfram System Modeler (free 30-day trial) plus a C++ compiler; and for post-processing, Wolfram Language connected to the assistant via the Wolfram Local MCP. It will flag anything missing; just follow its prompts.

That's it—now try it out. Ask for something real, for example:

"Create a hydraulic circuit with a pump and a double-acting cylinder, then validate it to check that it compiles."

"What's new in Wolfram System Modeler 15?"

The assistant will use the relevant skills to build, check and explain—citing its sources where it looked things up.

[!NOTE] Setting up in Claude Code, Codex or another agent, or curious about exactly what each skill needs? It's all in InstallationGuide.md—a guide your AI assistant reads to do the setup, not a manual you work through.
