What is cuda-webdoc-search?

A search guide for CUDA-X library documentation, including libraries such as cuBLAS, cuTENSOR, cuTensorNet, and cuSOLVER. CUDA-X is NVIDIA’s collection of GPU computing libraries.

Use it to search CUDA-X documentation inventories, check available API domains, find library operations, and obtain documentation links.

It helps locate the exact documented functions, types, and API symbols instead of guessing which CUDA library interface exists.

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 ultimatile/cuda-x-skills --skill cuda-webdoc-search

Clone the repo

git clone --depth 1 https://github.com/ultimatile/cuda-x-skills

Made for: Claude Code, Codex.

Its marketplace also offers this one on its own, as the plugin cuda-webdoc-search — /plugin install cuda-webdoc-search 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	$0.00062	$0.01561
Opus 5	$0.00031	$0.00781
Sonnet 5	$0.00012	$0.00312
Haiku 4.5	$0.00006	$0.00156

Security

Grade A, and why

cuda-webdoc-search 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 10d ago.

The scan reads SKILL.md. This mod also ships 12 executable files (audit.py, cli.py, fetchers.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.

CUDA-X Documentation Search Guide

Overview

Search and discover APIs across CUDA-X library documentation by querying Sphinx inventory files. Use this skill when you need to find specific CUDA library functions, check available APIs, or get documentation links.

Setup

uv tool install "cuda-webdoc-search @ git+https://github.com/ultimatile/cuda-x-skills.git#subdirectory=skills/cuda-webdoc-search"

After installation, cws is available as a standalone command. For one-shot usage without installing:

uvx --from "cuda-webdoc-search @ git+https://github.com/ultimatile/cuda-x-skills.git#subdirectory=skills/cuda-webdoc-search" cws search cublas --stats

When to Use

Finding CUDA library APIs (e.g., "what SVD functions does cuTensorNet have?")
Checking if a specific function exists in a library
Getting documentation URLs for CUDA APIs
Exploring available operations in a library

Quick Reference

Check Available Domains First

Before searching, check what domains (API types) are available:

cws search <library> --stats

This returns domain counts: cpp (C++ APIs), c (C APIs), py (Python bindings), std (doc labels).

Search for APIs

cws search <library> --domains <domain> --keywords "<terms>" --fuzzy --limit 20

Keyword Syntax (fzf subset)

Space-separated terms are AND (all must match): --keywords "SVD batch"
Use | for OR (requires shell quoting): --keywords "SVD | QR"
AND binds tighter than OR: --keywords "a b | c" = (a AND b) OR c
Note: Only AND/OR via | is supported. fzf operators ^, ', !, $ are not available.

Available Libraries

See registry.toml for the full list. Common ones:

cuquantum - cuTensorNet, cuStateVec (quantum/tensor network)
cublas - BLAS operations
cusolver - Dense/sparse solvers
cusparse - Sparse matrix operations
cufft - FFT operations
cudnn - Deep learning primitives
cutlass - GEMM templates
cuda_math - Math functions

Files

What ships with it

18 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-webdoc-search is a skill published in the GitHub repository ultimatile/cuda-x-skills (2 stars, last pushed 5mo ago), licensed MIT. It adds 62 tokens to every session and 1,561 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.
