Create and customize MATLAB charts and plots. An agent skill from matlab/matlab-agentic-toolkit.

  • Customizing axes
  • SKILL.md covers When to Use This Skill, When NOT to Use This Skill, Workflow and Rendering Context, plus 7 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Adding annotations

What it does

Matlab Build Chart is an agent skill from matlab/matlab-agentic-toolkit. Create and customize MATLAB charts and plots. Plot types (line, scatter, bar, histogram, heatmap, surface), axes configuration, annotations, data tips, interactive plots, animation, multiple axes with tiledlayout, colororder, and performance optimization. Works for standalone figures, Live Scripts, and uifigure apps. Use when plotting data, customizing axes, adding annotations or interactivity, animating charts, or arranging multiple axes. Triggers: plot, chart, graph, axes, uiaxes, annotation, data tips…

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `manifest.yaml`, `references/animation.md` and `references/annotations.md`).

It sits in Data & Analytics, covering Data visualization, Accessibility and Performance optimization. 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

  • Customizing axes
  • Adding annotations
  • Animating charts
  • Arranging multiple axes

Example prompts

  • “/matlab-build-chart”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash

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 these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash

    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

Matlab Build Chart loads about 3.5k tokens when it runs, and up to ~8.4k if it reads all its reference files. Until then it costs about 154 tokens; SKILL.md has 1,229 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~154
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.4k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Bash

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 1,229 words (~3,514 tokens).

“Create, customize, and interact with MATLAB charts and plots — in standalone figures, Live Scripts, or uifigure apps.”
