What it does
Building Architecture Models is an agent skill from matlab/simulink-agentic-toolkit. Common steps for building multi-layer system architecture models using System Composer. Use when implementing architecture models or when interacting with interface dictionaries, allocation sets, stereotypes, and requirements for architecture components.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `manifest.yaml`, `references/flp-reference-workflow.md` and `references/matlab-project.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
- Implementing architecture models
- Interacting with interface dictionaries
- Allocation sets
- Requirements for architecture components
Example prompts
- “/building-architecture-models”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- F/L/P = 3 separate Architecture models. There are no special model types (systemcomposer.createFunctionalModel does not exist). Layers are…
- Layer conventions
- Allocation links layers. Allocation sets map elements across models (F→L, L→P). Rebuilding a model invalidates allocation links because…
- Interface dictionaries are per-layer. Each layer has its own .sldd with interfaces at the appropriate abstraction. The dictionary must be…
- Stereotypes follow a strict lifecycle. Create profile → save → apply to model → apply stereotype to components → set properties…
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 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
Building Architecture Models loads about 1.3k tokens when it runs, and up to ~7k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 543 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 543 words (~1,311 tokens).
“Create and refine System Composer architecture models — from greenfield F/L/P designs to targeted additions (stereotypes, views, allocation sets, requirements tracing).”
