matlab-diagnose-parfor

matlab-diagnose-parfor is a skill for Claude Code from matlab/matlab-agentic-toolkit. It costs 161 tokens per session (3,540 once invoked), scanned A, original, no licence file.

A MATLAB troubleshooting guide for `parfor`, the MATLAB loop construct that runs iterations in parallel. It explains errors involving variable classification, sliced variables, reduction variables, and converting ordinary `for` loops.

In plain words
What is it for?
Use it to diagnose, fix, or rewrite MATLAB `parfor` loops that fail to run or produce variable-classification errors.
Why use it?
`parfor` has stricter rules about how variables are read and changed than a normal loop. Those rules can cause confusing errors when parallelizing existing code.

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-diagnose-parfor 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 1mo 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.

The source is not reproduced here

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 ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-diagnose-parfor is a skill published in the GitHub repository matlab/matlab-agentic-toolkit (1,207 stars, last pushed 4d ago), with no licence file. It adds 161 tokens to every session and 3,540 once invoked, about $0.0006 per session on Opus 5.5. 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.
