A reference and skill for NVIDIA CUDA C++, the tools and programming model used to run calculations on NVIDIA GPUs. It covers GPU programming, memory, parallel work, and performance practices.

Learning CUDA programming, managing GPU memory, coordinating asynchronous work, and applying CUDA performance practices.

Use it when writing or improving C++ code that should run computations on NVIDIA GPUs.

cuda — Skill for Claude Code and Codex by jstzwj

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add jstzwj/ai-infra-plugins --skill cuda

Clone the repo

git clone --depth 1 https://github.com/jstzwj/ai-infra-plugins

Made for: Claude Code, Codex.

Its marketplace also offers this one on its own, as the plugin cuda — /plugin install cuda after adding the marketplace above.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00133	$0.02963
Opus 5	$0.00067	$0.01482
Sonnet 5	$0.00027	$0.00593
Haiku 4.5	$0.00013	$0.00296

Security

Grade A, and why

cuda 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (examples/0_Introduction/matrixMulDynlinkJIT/extras/ptx2c.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.

What ships with it

60 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.

cuda is a skill published in the GitHub repository jstzwj/ai-infra-plugins (4 stars, last pushed 4mo ago), with no licence file. It adds 133 tokens to every session and 2,963 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 2026-08-31.
