jh-math-context-questions is a skill for Claude Code, Codex from mathruffian-dot/teaching-exam-skills. It costs 249 tokens per session (9,753 once invoked), scanned A, original, MIT.

A Chinese-language question-writing assistant for middle-school, real-life mathematics problems that require written answers rather than choosing from options.

In plain words
What is it for?
Use it to create five two-part questions around a requested maths topic, including shopping, climate, transport, health, technology, or finance contexts, and export them to a Word document.
Why use it?
It turns current events and everyday situations into structured practice questions with worked explanations and correctly formatted Word equations.

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 output/generate_exam_docx.py output/exam_data.json output/exam_output.docx.

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

jh-math-context-questions scanned grade A with 1 finding 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 7d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

國中數學生活情境非選擇題命題技能

技能概覽

本技能依使用者指定的國中數學單元,上網搜尋相關生活情境與時事新聞, 將真實素材轉化為非選擇題,並匯出格式正確的 Word 文件。

  • 五大題,每大題含兩小題
  • 第(1)小題:閱讀素材,理解條件即可作答(Bloom 第2級:理解)
  • 第(2)小題:承接第(1)題,結合數學單元,達到應用或分析層次(Bloom 第3-4級)
  • 每大題皆含完整解析
  • 幾何圖形支援:若題目涉及幾何情境,自動呼叫 jh-math-geometry 技能的渲染腳本產生 PNG 並插入 Word
  • 匯出 Word 文件,數學式以 OMML 正確格式呈現

數學標記語法(題目撰寫規則)

在題目文字中,用大括號 {} 包住數學式,系統會自動轉為 Word 正確格式:

標記語法 說明
{x^2} x 的平方(上標)
{x^{n+1}} 上標含運算式
{x_1} x 下標 1
{sqrt(2)} 根號 2
{sqrt3} 三次方根 8
{frac(3,4)} 分數 3/4
{(a+b)/2} 含運算式的分數
{ x-3
{<=} 小於等於符號
{>=} 大於等於符號
{!=} 不等於符號

規則:分數一律 {frac(分子,分母)}、次方一律 {x^2}、根號一律 {sqrt(x)}、不等號一律 {<=} {>=} {!=},不直接貼 ²、√ 等字元;簡單方程式(如 2x + 3 = 7)不需加 {}

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.
