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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.01620 | $0.01620 |
| Opus 5 | $0.00810 | $0.00810 |
| Sonnet 5 | $0.00324 | $0.00324 |
| Haiku 4.5 | $0.00162 | $0.00162 |
Grade A, and why
LumericalFDTD-skill CLAUDE.md 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This is a Claude Code Plugin
This repo defines the LumericalFDTD plugin with 5 skills and 4 slash commands:
| Skill | 用途 |
|---|---|
| LumericalFDTD | FDTD 全流程自动化 — 建模→仿真→分析→验收，端到端流水线 |
| LumericalFDTD-modeling | FDTD 结构建模 — 几何、材料、光源、监视器，输出建模脚本 |
| LumericalFDTD-simulation | FDTD 仿真执行 — 运行、自动debug、结果提取，输出 .fsp/.npz |
| LumericalFDTD-analysis | FDTD 数据分析 — 读取 .npz、计算指标、绘图，输出 .png |
| paper-summarizer | 学术论文深度总结 — 结构化中文报告，逐图逐表详细解释 |
| Command | 说明 |
|---|---|
/fdtd-model |
触发 LumericalFDTD-modeling — 仅建模 |
/fdtd-simulate |
触发 LumericalFDTD-simulation — 仅仿真 |
/fdtd-analyze |
触发 LumericalFDTD-analysis — 仅分析 |
/fdtd-full |
触发 LumericalFDTD — 全流程 |
There is no build, lint, test suite, or traditional CI pipeline. "Development" means editing skill files (skills/*/SKILL.md), command files (commands/*.md), and reference files (skills/*/references/).

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.

LumericalFDTD-skill CLAUDE.md is an instructions file published in the GitHub repository Lex669/LumericalFDTD-skill (23 stars, last pushed 15d ago), licensed MIT. It adds 1,620 tokens to every session, about $0.0081 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 2026-08-30.
