At a glance

A skill your agent uses when writing or editing Simscape Language (.ssc) source files — components, domains, or functions.

  • Editing Simscape Language (.ssc) source files — components
  • SKILL.md covers When to Use, When NOT to Use, Designing a component and Write the .ssc file, plus 1 more section
  • Include: model a physical component in .ssc
  • Write physical equations for a Simscape block

What it does

Simscape Write Ssc is an agent skill from matlab/simulink-agentic-toolkit. Use when writing or editing Simscape Language (.ssc) source files — components, domains, or functions. Triggers include: model a physical component in .ssc; write physical equations for a Simscape block; add or modify physics or parameterization options in a Simscape component; build a composite component. Also use for validating .ssc syntax, fixing Simscape Language errors, or converting governing equations into working Simscape component code. Do NOT use for configuring or connecting existing Simscape blocks in…

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 45 other files, including scripts, reference files and assets (for example `manifest.yaml`, `references/composition/arrays-of-nodes.md` and `references/composition/composite-components-and-connections.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

  • Editing Simscape Language (.ssc) source files — components
  • Include: model a physical component in .ssc
  • Write physical equations for a Simscape block
  • Parameterization options in a Simscape component

Example prompts

  • “/simscape-write-ssc”

What it can do on your machine

Read from SKILL.md and the folder at commit 455dded. 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 1 file 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

Simscape Write Ssc loads about 2.1k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 151 tokens; SKILL.md has 796 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~151
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~22k

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 796 words (~2,130 tokens).

“Write .ssc files (components, domains, functions) that pass validation and are physically correct.”
