fla-nvidia-performanceGuidelines for NVIDIA GPU kernel / Triton / Gluon / TileLang / CUDA backend performance work in the FLA repo.
Fla Nvidia Performance is an agent skill from fla-org/flash-linear-attention. Guidelines for NVIDIA GPU kernel / Triton / Gluon / TileLang / CUDA backend performance work in the FLA repo. Covers profiling workflow, hardware baselines, and PR-ready performance evidence requirements. Uses an installed ncu-report-skill when a task needs detailed Nsight Compute collection and diagnosis.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering. It works with NVIDIA AI Platform and CUDA. The repository describes itself as: 🚀 Efficient implementations for emerging model architectures. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 72ac946. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Fla Nvidia Performance loads about 1.2k tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 445 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
The full file from fla-org/flash-linear-attention at commit 72ac946, republished under its MIT licence (© fla-org). 445 words, ~1,155 tokens.
.claude/skills/fla-nvidia-performance/SKILL.md (or your agent's skills folder).Use this skill when working on Triton, Gluon, TileLang, CUDA, or other NVIDIA GPU kernel optimizations,
backend tuning, or any change that could affect throughput or latency in fla/ops/ or related modules.
This repo intentionally does not vendor ncu-report-skill, add it as a submodule, or auto-clone it during agent work.
If a user-level ncu-report-skill is available, use it for:
full, source, PM sampling, source counters);If it is not available, use the minimal NCU commands in this skill. Report any missing profiling evidence and its technical limitation; the availability of a helper skill does not belong in the PR description. Do not create untracked external clones inside this repo unless the user explicitly asks.
benchmark_training_throughput.py or benchmark_generation.py
are enough to catch large regressions during development.For NVIDIA performance-optimization PRs, collect the evidence below. Correctness-only kernel changes still need the tests and same-hardware benchmarks required by CONTRIBUTING.md; detailed profiling is needed when it explains a performance claim or unresolved regression.

Going by SKILL.md and its folder, Fla Nvidia Performance needs the command-line tools its instructions call (python). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Fla Nvidia Performance is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
