cutlass-skillWrite, debug, and optimize CUTLASS, CuTe, and CuTeDSL GPU kernels from local upstream source, examples, and headers.
Cutlass Skill is an agent skill from slowlyC/agent-gpu-skills. Write, debug, and optimize CUTLASS, CuTe, and CuTeDSL GPU kernels from local upstream source, examples, and headers. Use when the task explicitly involves CUTLASS/CuTe/CuTeDSL, cute::Layout, cute::Tensor, TiledMMA, TiledCopy, CollectiveBuilder, CollectiveMainloop, CollectiveEpilogue, GemmUniversal, KernelSchedule, EpilogueSchedule, CUTLASS pipelines, EVT, pycute, or CUTLASS template errors. Use cuda-skill for raw CUDA/PTX or NVIDIA architecture facts, and triton-skill for Triton or Gluon implementation work.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `quick-reference.md`).
It sits in AI & LLM Engineering. It works with CUDA, NVIDIA AI Platform, Python and C++. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit ae02d07. 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:
rgbashcmakepython3From 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.
Cutlass Skill loads about 1.3k tokens when it runs. Until then it costs about 132 tokens; SKILL.md has 436 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.

.claude/skills/cutlass-skill/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Use the local CUTLASS checkout as the primary implementation reference. Prefer current source and examples over remembered APIs because CuTeDSL paths and interfaces change frequently.
Resolve the directory containing this SKILL.md, then use its repos/cutlass/ child. The installer links that path to agent-gpu-skills/third_party/cutlass/ or to the checkout supplied through CUTLASS_REPO.
In commands below, replace CUTLASS_REPO with the resolved absolute path:
CUTLASS_REPO=/absolute/path/to/cutlass-skill/repos/cutlassIf the checkout is missing, run this from the agent-gpu-skills repository and reinstall the Skill:
bash update-repos.sh cutlass
bash install.sh --skill cutlass-skill| Task | Start here |
|---|---|
| CuTeDSL API and implementation | python/CuTeDSL/cutlass/ |
| All CuTeDSL examples and tutorials | examples/python/CuTeDSL/ |
| CUTLASS C++ examples | examples/ |

| CuTe C++ layout, copy, and MMA | include/cute/ |
| Python layout and swizzle utilities | python/pycute/ |
| Python manifest and generator utilities | python/cutlass_library/ |
Read quick-reference.md when mapping an operation or architecture to a concrete file in the validated checkout.
Discover files before loading a large source file:
find "$CUTLASS_REPO/examples/python/CuTeDSL" -type f | sort
find "$CUTLASS_REPO/examples" -mindepth 1 -maxdepth 1 -type d | sortSearch CuTeDSL definitions and usage together:
rg -n 'TiledMMA|tiled_mma' \
"$CUTLASS_REPO/python/CuTeDSL/cutlass/cute" \
"$CUTLASS_REPO/examples/python/CuTeDSL"
rg -n 'Pipeline|pipeline' \

rg -n 'CollectiveMainloop' \

rg -n 'TiledCopy|make_tiled_copy' "$CUTLASS_REPO/include/cute"
rg -n 'SM90_TMA|SM100_TMA' "$CUTLASS_REPO/include/cute/arch"For a C++ example, inspect its CMakeLists.txt and build only the selected target. Replace the architecture and target below for the workload:
cmake -S "$CUTLASS_REPO" -B /tmp/cutlass-build -DCUTLASS_NVCC_ARCHS=100a
cmake --build /tmp/cutlass-build \
--target 71_blackwell_gemm_with_collective_builderBefore running a CuTeDSL example, inspect the current python/CuTeDSL/pyproject.toml and requirements files instead of assuming a compatible CUDA or Python version.
Keep three layers separate when diagnosing a CUTLASS kernel:
problem shape and tensor layout
→ selected collective and schedule
→ generated CUDA/PTX behavior on the target architectureDo not infer the selected schedule from an example directory name. Follow the instantiated types and builder parameters. When an architecture or instruction detail determines correctness, add cuda-skill and verify it against the CUDA or PTX reference.
For correctness work:
For performance work:

Run `npx skills add slowlyC/agent-gpu-skills --skill cutlass-skill -a claude-code`. Or copy the skill folder (skills/cutlass-skill in slowlyC/agent-gpu-skills) into .claude/skills/cutlass-skill in your project. Claude Code loads it when a task matches its description.
Run `npx skills add slowlyC/agent-gpu-skills --skill cutlass-skill -a codex`. Or copy the skill folder (skills/cutlass-skill in slowlyC/agent-gpu-skills) into .agents/skills/cutlass-skill in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add slowlyC/agent-gpu-skills --skill cutlass-skill -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cutlass-skill, .gemini/skills/cutlass-skill, .github/skills/cutlass-skill and .opencode/skills/cutlass-skill in your project.
Going by SKILL.md and its folder, Cutlass Skill needs the command-line tools its instructions call (rg, bash, cmake and python3). 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.
Cutlass Skill is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.3k tokens (SKILL.md is roughly 5.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
