Is the Building Simulink Models skill free?

Yes. The skill itself is free from matlab/simulink-agentic-toolkit. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Building Simulink Models SkillProof Score?

8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.

How do I install Building Simulink Models?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Building Simulink Models with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 8.0/10
Tested: Jul 21, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 3fae9da

Located SKILL.md via the GitHub tree API at skills-catalog/model-based-design-core/building-simulink-models/. Frontmatter parses cleanly with name+description; all four body-referenced files (manifest.yaml, references/stateflow.md, references/simscape.md, references/system-composer.md) returned HTTP 200 on raw fetch; no security smells. Trigger judgment: 3 model-editing phrasings (add PID subsystem, add Stateflow state+transition, wire Simscape resistor/voltage source) load it; 2 adjacent ones (query a Gain's Kp value, run a simulation) correctly do not, matching the skill's explicit When-NOT-to-Use and sibling skills. Output stage was not runnable: every workflow step depends on the MATLAB MCP tools (model_edit/model_read/model_check) which need MATLAB R2023a+ with Simulink installed — I could not execute a single model_edit call, so no artifact was produced.

What Building Simulink Models does

Guides an agent through building and editing Simulink, System Composer, Stateflow, and Simscape models using the MATLAB MCP server's model_edit/model_read/model_check tools, enforcing a library-policy gate, read-before-edit workflow, and code-generation-safe naming. Triggers when the user asks to add, connect, delete, or replace blocks, configure parameters or ports, or edit Stateflow chart internals. Does not trigger for querying parameter values or running simulations, which are handled by sibling skills.

How to install Building Simulink Models

git clone --depth 1 https://github.com/matlab/simulink-agentic-toolkit.git /tmp/building-simulink-models-src
mkdir -p ~/.claude/skills
cp -R /tmp/building-simulink-models-src/skills-catalog/model-based-design-core/building-simulink-models ~/.claude/skills/building-simulink-models
# REQUIRES: MATLAB R2023a+ with Simulink, plus the MATLAB MCP Server (https://github.com/matlab/matlab-mcp-core-server)
# which provides the model_edit, model_read, model_check, model_query_params, model_resolve_params tools.
# The skill is inert without those MCP tools connected. Repo ships an automated MATLAB setup — see README.md.
# Depends on sibling skill setup-custom-libraries for the library/policy gate.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Building Simulink Models

/building-simulink-models Edit Simulink, Stateflow, Simscape and System Composer models via MATLAB MCP tools

It also activates on plain-language prompts like these:

Add a new Stateflow chart to this model
Connect these two Simulink blocks with a signal line
Modify the ports on this System Composer architecture
