lsdyna-kagent

A coding agent for creating LS-DYNA K-files, which are input files describing engineering simulations such as crashes, drops, penetration, forming, and fluid-like material behavior.

In plain words
What is it for?
It helps build meshes, choose materials, look up solver keywords, check decks, and verify them with a local LS-DYNA solver.
Why use it?
It turns a simulation request into a checked solver input deck and can identify problems through a run-and-fix cycle.

Security

Grade A, and why

lsdyna-kagent 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 2d 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 ships with it

1 file beside plugin.json 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.

lsdyna-kagent is a plugin published in the GitHub repository LLK-LL/K-agent (8 stars, last pushed 29d ago), licensed MIT. 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 2026-08-31.
