matlab-simulink-modeling

matlab-simulink-modeling is a skill for Claude Code, Codex from wzyn20051216/matlab-agent-skills. It costs 0 tokens per session (1,610 once invoked), scanned A, original, MIT.

A workflow for creating, inspecting, changing, simulating, checking, and exporting MATLAB Simulink models. Simulink is MATLAB software for building systems from connected blocks and testing how they behave over time.

In plain words
What is it for?
Use it for Simulink, Stateflow, Simscape, model-based design, parameter sweeps, signal logging, requirements, and simulation automation. It also covers working with model files ending in .slx.
Why use it?
It provides a defined process for safely editing models while checking their structure, settings, signals, and simulation results.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

matlab-simulink-modeling scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use this skill for model-based design and simulation workflows.

First Checks

  1. Confirm the product with the precheck, not by guessing a license string:

    r = mas_precheck('toolbox', 'Simulink Coder');   % installed + licensed, with reason

    license('test', X) takes a FEATURE name, and passing the display name returns 0 even when the product is licensed (Deep_Learning_Toolbox → 0 while Neural_Network_Toolbox → 1 on R2026a). The verified map lives in ../matlab-runner/references/toolbox-feature-map.md. An earlier revision of this file pointed at masacc.availability, which does not exist anywhere — removed.

  2. Prefer an official MATLAB MCP auto session tied to a visible MATLAB/Simulink desktop before substantial edits. Use load_system, open_system, and set_param(modelName,"ZoomFactor","FitSystem") so the user can see the model.

  3. Audit topology before editing: blocks, lines, solver config, sample times, logged signals.

  4. Prefer existing model architecture and naming.

  5. Save a copy before destructive edits to user models.

Visible Workflow Requirement

The user specifically wants to watch Simulink modeling and simulation, not only receive final artifacts. Default to this sequence unless the user explicitly asks for headless-only execution:

  1. Bring up a visible MATLAB/Simulink window first.
  2. For an existing model, run: 
    load_system(modelPath)
open_system(modelName)
set_param(modelName,"ZoomFactor","FitSystem")
  3. For a new model, call new_system, save it under artifacts/models/ or the project model folder, then immediately open_system before adding the rest of the blocks.
  4. During automated construction, save and refresh the model at meaningful milestones so the user can see progress: plant, controller, feedback path, logging/scopes, and final layout.
  5. During simulation and tuning, open Scope blocks or MATLAB figures and update/plot each run so the user can see response changes.
  6. If the model window does not appear, do not assume success. Verify the visible window title if possible and retry by focusing MATLAB's command window and executing open_system there.
  7. Still export .slx, data, figures, logs, and validation reports for reproducibility after the visible demonstration.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

matlab-simulink-modeling is a skill published in the GitHub repository wzyn20051216/matlab-agent-skills (27 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,610 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
