matlab

matlab is a skill for Claude Code from K-Dense-AI/scientific-agent-skills. It costs 42 tokens per session (3,571 once invoked), scanned A, original, MIT.

Guidance and tools for building, reviewing, migrating, and safely planning numerical workflows in MATLAB or GNU Octave. It covers arrays, tables, time data, tests, graphics, MAT files, projects, and Python interoperability.

In plain words
What is it for?
Use it to design or review numerical code, migrate between MATLAB releases, prepare reproducible projects, work with scientific files and graphics, add tests, and plan MATLAB–Python integration.
Why use it?
It helps avoid assuming that MATLAB and Octave are interchangeable, or that a particular release, toolbox, runtime, or licence is available.

About the project

Scientific Agent Skills is a collection of reusable procedures that give AI agents capabilities for scientific research across areas such as biology, chemistry, medicine, and drug discovery. It is used by researchers and by people building AI scientist workflows with compatible coding agents. The catalogue contains many of the project's skills and supporting instructions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

matlab scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/_common.py, scripts/generate_function_scaffold.py, scripts/inventory_mat_file.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MATLAB and GNU Octave

Use this skill to design or review numerical code, migrate MATLAB releases, prepare reproducible projects, and plan trusted execution. MATLAB and GNU Octave are distinct products: compatibility is partial, not a license or behavior guarantee.

Product and license gate

  • MATLAB R2026a is proprietary. Do not assume MATLAB, MATLAB Online, a named toolbox, MATLAB Test, MATLAB Compiler, MATLAB Coder, Parallel Computing Toolbox, or an add-on is installed, licensed, or available to the user.
  • MATLAB Runtime is not MATLAB. It runs compatible applications produced with MATLAB Compiler; it cannot run arbitrary source or host MATLAB Engine for Python. Building artifacts needs the applicable licensed compiler and every product used by the source.
  • GNU Octave 11.3.0 is free software under GPLv3+. Octave packages are not MATLAB toolboxes. Similar names do not imply API, numerical, graphics, or licensing equivalence.
  • Ask which runtime, release, platform, installed products, and license context the user actually has. Treat availability as unknown until confirmed.

See Octave compatibility and execution/product boundaries.

Nonnegotiable safety boundary

Never run an untrusted .m, .mlx, MEX binary, MAT file, project startup or shutdown action, package installer, or generated artifact. Static review does not prove safety.

Treat these as execution or code-loading surfaces:

  • eval, evalin, assignin, text-derived feval, str2func, callbacks, timers, app callbacks, and dynamically modified paths;
  • system, unix, dos, shell escape !, Java, .NET, Python (py.*, pyrun, pyrunfile), MEX, and native libraries;
  • mex, codegen, MATLAB Compiler, build tasks, package/project startup, and generated code;
  • load, object deserialization (loadobj, custom serialization), function handles, Java/System objects, and class code reachable from MAT files.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

matlab is a skill published in the GitHub repository K-Dense-AI/scientific-agent-skills (44,220 stars, last pushed 4d ago), licensed MIT. It adds 42 tokens to every session and 3,571 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
