blas_lapack

blas_lapack is a plugin for Claude Code from datathings/marketplace. Its manifest loads nothing; the 1 skill it bundles cost 133 tokens per session together, scanned A, original, Apache-2.0.

A C-language reference for BLAS and LAPACK, libraries used for fast vector, matrix, and other numerical calculations. It covers operations such as solving equations, finding eigenvalues, computing singular value decompositions, and least-squares fitting.

In plain words
What is it for?
It helps with C programs that perform matrix calculations, solve linear systems, factor matrices, calculate eigenvectors or singular values, and run other scientific-computing routines.
Why use it?
It gives a coding agent detailed information about a large numerical API, reducing the need to search through separate documentation while writing scientific or engineering code.

Security

Grade A, and why

blas_lapack 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 4d 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 it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 133 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
