hfss-search

hfss-search is a skill for Claude Code, Codex from K-13ROBOT/HFSS_MCP. It costs 125 tokens per session (3,374 once invoked), scanned A, original, MIT.

A research workflow for finding antenna papers and extracting reusable design methods, formulas, and starting dimensions. It first checks a local library of previously verified designs before searching external literature.

In plain words
What is it for?
Use it to find reference papers, study a supplied PDF, compare candidate antenna topologies, and prepare a structure summary for later HFSS modeling.
Why use it?
It helps turn a design goal or paper into a documented antenna structure and initial dimensions without confusing literature research with simulation or modeling.

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.

Security

Grade A, and why

hfss-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 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.

天线文献检索与提炼

补的是 hfss-design 的 flow/design-loop.md 第 1 步那个死胡同:卡片库没有匹配拓扑时怎么办。 本 skill 的交付物是**「结构理解表 + 起手尺寸」交用户确认**,不是卡片 —— 卡片是整条流程走完、 仿真达标、用户点头之后才录的(见 §5)。

0. 先查本地库 —— 硬门槛,不许跳

任何情况下先调 search_designs(传 frequency_ghz / polarization / topology / min_gain_dbi), 命中就用 read_design_card 取正文,直接走 hfss-design 的 flow/design-loop.md 第 2 步缩放建模,不要联网。 只有确认库里没有可用拓扑,才进本 skill 后续步骤。

理由:库里的卡是自己验证过的,可信度和可用性都高于任何论文;联网检索慢且贵。

1. 指标 → 拓扑候选 → 检索式

先把用户指标翻成拓扑候选,再翻成英文检索词。中文检索天线文献基本无效,检索式一律用英文。

指标 → 拓扑的常用映射(候选,不是唯一解):

指标特征 优先考虑的拓扑 检索关键词
窄带、低剖面、低成本 矩形/圆形微带贴片 microstrip patch antenna
圆极化(单馈) 切角/开槽贴片 single-fed circularly polarized patch, truncated corner
圆极化(宽轴比带宽) 双馈+90°电桥、序列旋转 dual-fed CP antenna, sequential rotation
宽带(>30%) 磁电偶极子、E 型/U 型开槽贴片、堆叠贴片 magneto-electric dipole, E-shaped patch, stacked patch
高增益(单元) 缝隙耦合叠层、SIW、介质谐振 aperture-coupled stacked, SIW antenna, dielectric resonator antenna
高增益(阵列) 微带阵 + 馈电网络 microstrip array, series-fed, corporate feed
宽波束/半球覆盖 单极子、PIFA、缝隙 monopole, PIFA, slot antenna
毫米波 SIW、贴片阵、透镜 mmWave antenna, substrate integrated waveguide
双频/多频 开槽、寄生单元、分形 dual-band patch, parasitic element

检索式模板(按需组合,别一次堆太多词,先宽后窄):

<拓扑关键词> AND (<频段词>) AND (<性能约束>)
如: "magneto-electric dipole" AND "5G" AND "wideband"
    "circularly polarized patch" AND "axial ratio bandwidth" AND "single feed"

频段词用应用名往往比数字好使(sub-6 GHz / 5G n78 / WLAN 2.4 GHz / Ka-band), 因为论文标题里写应用名的比写具体频率的多。

2. 检索源与分工

我能自主做的(有联网工具时):

  • WebSearch 找综述和公开可读的论文,快速摸清这类天线有哪些主流做法
  • IEEE Xplore 的检索结果页通常可读(标题/摘要/DOI),据此出候选清单
  • arXiv(eess.SP 有部分天线文章)、MDPI 系期刊、开放获取论文可直接读全文

必须用户做的:下载 IEEE / 付费期刊的 PDF。我的网页抓取不带用户的登录态和学校 IP, 拿回来只会是登录页。所以流程是:我给候选清单和链接 → 用户下载 → 把 PDF 路径告诉我。

别做批量下载。 出版商对高频抓取有风控,触发会封整个机构的 IP 段,代价由全校承担。 每轮候选控制在 35 篇,选定 12 篇精读即可。

没有联网工具时(换了 MCP 客户端 / 无网):直接请用户提供论文 PDF 或粘贴关键段落, 跳到 §3 精读。本 skill 的提炼纪律不依赖联网。

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.

hfss-search is a skill published in the GitHub repository K-13ROBOT/HFSS_MCP (8 stars, last pushed 2d ago), licensed MIT. It adds 125 tokens to every session and 3,374 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-09-09.
