Profile and tune Llaminar V2 CUDA kernels using LLAMINAR_PROFILING (per-kernel + per-stage timing), Nsight Systems (nsys), and Nsight Compute (ncu), then validate with the GEMM perf-test harness, the benchmark subcommand, and parity tests. Use when asked to find the slowest CUDA kernel, diagnose occupancy / register pressure / memory-bound stalls, A/B two kernel variants, or close a prefill/decode throughput gap while keeping PyTorch parity.
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
52 critical findings reported by cisco-skill-scanner, 28 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'llaminar/llaminar (cuda-kernel-profiling)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'llaminar/llaminar (cuda-kernel-profiling)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
5 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 269 findings across every scanner that examined this package. 24 of 52 findings rated critical by their scanner were among the dismissals.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

12 SOCIAL_ENG_VAGUE_DESCRIPTION
Artifact contains critical command injection and system modification capabilities.
The artifact includes multiple instances of potential command injection via `eval` in Python files, notably in `/repo/python/reference/base.py` and `/repo/python/train_cuda_neural_network.py`. It also contains scripts that perform system modification, specifically `/repo/scripts/setup-pcie-bar-access.sh`. Additionally, there are indications of prompt injection vulnerabilities in Jinja templates located at `/repo/jinja/qwen/qwen35/template.jinja`.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
