What it does
Testing Simulink Models is an agent skill from matlab/simulink-agentic-toolkit. Tests Simulink models using either ephemeral Gherkin-based tests (modeltest) for quick validation or persistent tests (Simulink Test API) authored from requirements or behavioral specs. Requires Simulink Test.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 34 other files, including scripts, reference files and assets (for example `assets/test-config-template.md`, `assets/test-structure-template.md` and `manifest.yaml`).
The repository describes itself as: The Simulink Agentic Toolkit gives your AI agent both the tools and the expertise to work effectively with Simulink and Model-Based Design.
Example prompts
- “Use the testing-simulink-models skill to test Simulink models using either ephemeral Gherkin-based tests (modeltest) for quick validation or…”
- “/testing-simulink-models”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Understand the component: Use model_overview and model_read on the target subsystem to identify inputs, outputs, and expected behavior.
- Write the .feature file: Author a Gherkin test following the syntax in references/gherkin-based-fast-testing.md. Start with one scenario…
- Cap StopTime before running: Check the model's StopTime with model_query_params. If it is inf (or unset/auto), you MUST pass a finite stop…
- Run in draft mode: Call model_test with draft_mode='true' for rapid iteration (~3s). Fix syntax or signal errors.
- Run full compilation: Once draft passes, re-run with draft_mode='false' to validate against the actual compiled model (catches…
- Expand coverage: Add scenarios for edge cases, fault conditions, and boundary behavior. Use coverage='decision' to identify untested…
What it can do on your machine
Read from SKILL.md and the folder at commit c58e6ae. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 6 files in scripts/, which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Testing Simulink Models loads about 1.6k tokens when it runs, and up to ~6.4k if it reads all its reference files. Until then it costs about 59 tokens; SKILL.md has 731 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 731 words (~1,599 tokens).
“Requires Simulink Test and R2023a or later. The requirement-driven entry point also requires Requirements Toolbox. The coverage workflow also requires Simulink Coverage. If Simulink Test is unavailable, use simulating-simulink-models with manual assertions.”

Codex loads it when a task matches its description.
Can I use Testing Simulink Models in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add matlab/simulink-agentic-toolkit --skill testing-simulink-models -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/testing-simulink-models, .gemini/skills/testing-simulink-models, .github/skills/testing-simulink-models and .opencode/skills/testing-simulink-models in your project.
What does Testing Simulink Models need to run?
SKILL.md names no scripts, command-line tools or credentials: Testing Simulink Models is instructions for the agent only.
Does Testing Simulink Models access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Testing Simulink Models safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Testing Simulink Models use?
Testing Simulink Models has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Testing Simulink Models use?
About 1.6k tokens (SKILL.md is roughly 6.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 4.8k tokens, read only when the agent opens those files.
