optimize-cuda

optimize-cuda is a skill for Claude Code, Codex from JackTan25/autocuda. It costs 68 tokens per session (2,652 once invoked), scanned A, original, no licence file.

A skill that tests CUDA code changes by checking correctness and measuring speed. CUDA is NVIDIA's technology for running computations on graphics processors; the skill requires a project-layout.md file created by discover-cuda.

In plain words
What is it for?
Trying CUDA source changes, validating them, benchmarking performance, and keeping or discarding changes based on measurements.
Why use it?
It helps determine whether an optimization really makes CUDA software faster without breaking its results.

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

optimize-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 3d 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.

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.

optimize-cuda is a skill published in the GitHub repository JackTan25/autocuda (2 stars, last pushed 4mo ago), with no licence file. It adds 68 tokens to every session and 2,652 once invoked, about $0.0003 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.
