matlab-modernize-code

matlab-modernize-code is a skill for Claude Code from matlab/matlab-agentic-toolkit. It costs 139 tokens per session (2,558 once invoked), scanned A, original, no licence file.

A guide for replacing MATLAB functions and coding patterns that are discouraged, scheduled for removal, or already removed. It focuses on updating older MATLAB code for newer releases.

In plain words
What is it for?
Use it when migrating legacy code or responding to checkmatlabcode reports about unsupported or discouraged functions and patterns.
Why use it?
It helps prevent warnings and failures caused by relying on outdated MATLAB features. Updating these parts makes future release upgrades easier.

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-modernize-code 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.

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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What this file has done since we first saw it

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-modernize-code is a skill published in the GitHub repository matlab/matlab-agentic-toolkit (1,030 stars, last pushed yesterday), with no licence file. It adds 139 tokens to every session and 2,558 once invoked, about $0.0007 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.
