What it does

Matlab Build App is an agent skill from matlab/matlab-agentic-toolkit. Build MATLAB apps from requirements to working code. Asks discovery questions (or skips them when the path is known), recommends UIFigure or UIHTML architecture, identifies layout archetype (Dashboard, Explorer, Tabbed, Wizard, Canvas), produces an implementation plan, and executes the build. For UIFigure apps, optionally serializes as App Designer (.mlapp or plain-text .m + .xml). Use when a user wants to build a MATLAB app, create a GUI, make an interactive tool, build a uifigure app, build a uihtml app, build…

Its SKILL.md is about 5.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 76 other files, including scripts, reference files and assets (for example `manifest.yaml`, `references/app-designer/agent-guide-mlapp.md` and `references/app-designer/agent-guide-plaintext.md`).

It sits in Agent Workflows, covering Requirements gathering and Planning. 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

  • A user wants to build a MATLAB app
  • Make an interactive tool
  • Build a uifigure app
  • Build a uihtml app

Example prompts

  • “/matlab-build-app”

Requirements

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

Workflow steps

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

  1. Read the archetype reference for the spatial skeleton
  2. If MVVM warranted (Explorer, Wizard, Canvas, or complex apps): read the architecture reference
  3. Read the UIFigure guide to establish layout (grid, components, containers)
  4. Layer in path-specific references per the implementation sequence
  5. For visual polish: invoke matlab-apply-theme (UIFigure) or read styling references (UIHTML accent)
  6. For charts: invoke matlab-build-chart (UIFigure) or read charting references (UIHTML accent)
  7. If App Designer serialization: read the app-designer reference docs (shared guide + format-specific guide), then use the…

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
    • Grep
    • Glob

    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

Matlab Build App loads about 5.3k tokens when it runs, and up to ~99k if it reads all its reference files. Until then it costs about 193 tokens; SKILL.md has 1,828 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~193
When it runs · the whole SKILL.md, loaded when a task matches
~5.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~99k

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, Grep, Glob

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 1,828 words (~5,285 tokens).

“Determine the best architecture for a MATLAB application, produce an implementation plan grounded in internal references, and execute the build. For UIFigure apps, optionally serialize into an App Designer format.”

What does Matlab Build App need to run?

SKILL.md names no scripts, command-line tools or credentials: Matlab Build App is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash, Grep, Glob.

Does Matlab Build App 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 Build App safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. 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.

What licence does Matlab Build App use?

Matlab Build App has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Matlab Build App use?

About 5.3k tokens (SKILL.md is roughly 21k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 93k tokens, read only when the agent opens those files.

What are the alternatives to Matlab Build App?

Skills that share tags, products or a category with Matlab Build App: Interview Me (addyosmani/agent-skills, 103k stars), Brainstorming Before Building (jnMetaCode/superpowers-zh, 8.3k stars), ULW Plan Workflow (code-yeongyu/oh-my-openagent, 70k stars) and Intent Router (angel291592/Intent-Router, 971 stars).
