What it does

Simulink Run Parallel Simulations is an agent skill from matlab/simulink-agentic-toolkit. Use this skill to run multiple Simulink simulations in parallel with parsim, batchsim, and DesignStudy. TRIGGER when: user asks for parameter sweep, sweeping/varying parameters across simulations, Monte Carlo study, batch simulation, running multiple simulations, parallel simulations, large-scale multiple simulations, any task involving repeated simulations with different parameter values, user mentions having an existing script/function for parameter sweeps, or user wants to migrate from parfor/setparam/for-loop…

Its SKILL.md is about 5.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `manifest.yaml`, `references/debugging.md` and `references/designstudy-and-batchsim.md`).

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.

When your agent uses it

  • Run multiple Simulink simulations in parallel with parsim
  • : user asks for parameter sweep
  • Sweeping/varying parameters across simulations
  • Monte Carlo study

Example prompts

  • “/simulink-run-parallel-simulations”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Project setup — Before discovery, cd to the project folder if provided and open the Simulink project (openProject) if a .prj exists. This…
  2. Discovery findings — Read-only inspection (no simulations). Report these as facts (no confirmation needed)
  3. Simulation plan — The decisions the user approves. Present as numbered points; end with: "Shall I proceed? To adjust, reference any point…
  4. Write the script — Only after the user confirms. Before writing, read the reference file(s) for every topic the task touches (see…
  5. Test run, then expand — For large campaigns (N ≥ 500), first run the script on the first 2 SimulationInputs (in(1:2)) over only a few time…
  6. Analyze and visualize — Use markers + lines for plots.
  7. Always ask for next steps — After the sweep, suggest plotting, finding optimal values, flagging outliers, checking requirements, or…

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are matlab).

    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

Simulink Run Parallel Simulations loads about 5.1k tokens when it runs, and up to ~9.1k if it reads all its reference files. Until then it costs about 147 tokens; SKILL.md has 2,375 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~147
When it runs · the whole SKILL.md, loaded when a task matches
~5.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.1k

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); files beside SKILL.md 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 2,375 words (~5,074 tokens).

“Set up and run parallel simulations with parsim, batchsim, or simulink.multisim.DesignStudy.”
