matlab-optimize-gpu-codegen

A MATLAB workflow for improving designs intended for GPU Coder, which generates CUDA code for NVIDIA GPUs.

In plain words
What is it for?
Use it to profile GPU MEX files or generated CUDA code, rewrite MATLAB designs, and benchmark repeated performance improvements.
Why use it?
It helps find slow parts of GPU code, apply changes, and check whether the generated code meets performance goals or has unresolved diagnostics.

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-optimize-gpu-codegen 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 2d 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.

Files

What ships with it

4 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-optimize-gpu-codegen is a skill published in the GitHub repository matlab/matlab-agentic-toolkit (993 stars, last pushed 5d ago), with no licence file. It adds 104 tokens to every session and 4,560 once invoked, about $0.0005 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 2026-08-30.
