What it does

Matlab Model Ams Systems is an agent skill from matlab/matlab-agentic-toolkit. Model a Phase-Locked Loop (PLL) IC from its datasheet or system specs using Mixed-Signal Blockset. Without this skill, agents universally select the wrong solver and produce non-functional PLL models — 100% of unguided attempts fail. Covers Integer-N, Fractional-N, Dual Modulus architectures, loop filter design, lock time optimization, VCO phase noise configuration, and msbPllArchitectures/msbPllFoundation block assembly. Use when: PLL modeling, frequency synthesizer design, phase noise simulation, lock time…

Its SKILL.md is about 5.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts and reference files (for example `manifest.yaml`, `references/assembly-code.md` and `references/datasheet-extraction.md`).

The repository describes itself as: The MATLAB Agentic Toolkit brings proven MATLAB capabilities to AI agents, making engineering and scientific workflows agent-ready.

When your agent uses it

  • Frequency synthesizer design
  • Phase noise simulation
  • Lock time analysis
  • Charge pump design

Example prompts

  • “/matlab-model-ams-systems”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Extract Datasheet Parameters
  2. Select Assembly Strategy
  3. Create Custom Blocks / Customize Architecture
  4. Assemble the Model

What it can do on your machine

Read from SKILL.md and the folder at commit 59dfd92. 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 2 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

Matlab Model Ams Systems loads about 5.8k tokens when it runs, and up to ~24k if it reads all its reference files. Until then it costs about 164 tokens; SKILL.md has 2,150 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~164
When it runs · the whole SKILL.md, loaded when a task matches
~5.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~24k

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 2,150 words (~5,791 tokens).

“Model a PLL IC from its datasheet or system specifications using Simulink building blocks from the Mixed-Signal Blockset (MSB) foundation library msbPllFoundation.”

What does Matlab Model Ams Systems need to run?

SKILL.md names no scripts, command-line tools or credentials: Matlab Model Ams Systems is instructions for the agent only.

Does Matlab Model Ams Systems 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 Matlab Model Ams Systems 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.
