core-numerical

core-numerical is a plugin for Claude Code from HeshamFS/materials-simulation-skills. Its manifest loads nothing; the 8 skills it bundles cost 1,002 tokens per session together, scanned A, original, Apache-2.0.

A set of numerical-computing skills for solving mathematical problems in scientific software, including equations, integration, meshes, and time-dependent calculations.

In plain words
What is it for?
Use it to work on linear and nonlinear solvers, numerical integration, differentiation, mesh generation, stability, and time-stepping.
Why use it?
It helps developers choose and reason about common numerical methods when building or reviewing simulation code.

Security

Grade A, and why

core-numerical 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 1mo 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. 8 skills travel with it, and installing the plugin installs all of them — 1,002 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#core-numerical 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.

core-numerical is a plugin published in the GitHub repository HeshamFS/materials-simulation-skills (75 stars, last pushed 3mo ago), licensed Apache-2.0. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-09-03.
