ez-math-model

ez-math-model is a skill for Claude Code from woodfishhhh/EZ_math_model. It costs 48 tokens per session (3,637 once invoked), scanned A, original, MIT.

A complete workflow for mathematical modelling competitions such as CUMCM, MCM, and ICM. It takes a problem through interpretation, model selection, Python solving, figures, paper writing, quality checks, and packaged delivery.

In plain words
What is it for?
It is for solving modelling problems, generating analysis and figures, writing the accompanying paper, auditing the results, and creating a final ZIP package.
Why use it?
It provides a defined path from a competition problem to checked submission files, including checks for charts, formulas, tables, and exported documents.

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

ez-math-model 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 7d ago.

The scan reads SKILL.md. This mod also ships 21 executable files (external/paper-orchestra/setup.sh, external/paper-orchestra/skills/agent-research-aggregator/scripts/discover_logs.py, external/paper-orchestra/skills/agent-research-aggregator/scripts/extract_experiments.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

ez-math-model

数学建模一站式 skill。把题目交给我,我会自动走完七个阶段:setup → 题目解析 → 建模方案 → 代码求解 → 论文撰写 → 质量审查 → 标准打包交付。首次使用必须完成 setup 提问;完成后写入 external/tools/setup_state.json。未经用户确认,只能使用本次临时默认, 不得写永久配置。

一句话主流程

收到题目 → 识别项目总文件夹 → 检查 external/tools/setup_state.json → 创建 用户输入/runtime/output 标准目录 → 判定 formal/demo/blocked → 识别赛事/年份/题号 → 选择模型 → 写脚本并执行 → 出图并过 chart gate → 写论文 → 跑对象级质量门 → staging 导出与审查 → 原子同步到 output/ 并打包 output.zip

触发后的第一动作

先读以下七份文件确认本次运行的契约:

  1. pipeline/00-environment-setup.md — 验环境(Python、字体、工作目录、上游缓存状态)
  2. references/project-root-protocol.md — 项目总文件夹与 用户输入/runtime/output
  3. references/setup-policy.md — setup 硬门与临时默认边界
  4. references/run-mode-protocol.mdformal/demo/blocked 判定
  5. references/workdir-protocol.md — runtime 产物结构与命名
  6. references/chart-quality-gate.md — 图表有效性门
  7. references/artifact-manifest.md — 产物 manifest 契约

formal 交付不得只检查“文件是否存在”。质量门必须覆盖图表语义、公式语法、 表格对象、优秀论文格式抽取、正文工程痕迹、DOCX/PDF 对象级导出和 zip/manifest 一致性。

然后立刻执行 setup gate:

  • 读取 external/tools/setup_state.json
  • 若文件不存在、JSON 无法解析、setup_completed 不是 true,或用户说"重新配置工具 / 重置 setup / 重新 setup",必须先运行 pipeline 00 的强制提问,禁止进入 pipeline 01、建模、写代码或写论文。
  • setup 提问完成后,必须写入 external/tools/setup_state.json,再继续本次任务。
  • setup_completed: true,默认跳过交互式 setup,只做本次任务所需的轻量环境检查 和工作目录创建。

不要用"默认不追问"绕过首次 setup;首次 setup 是硬门禁。若用户要求继续但无法 完成交互式 setup,只能写 runtime/{task_id}/setup_assumptions.json,并把 setup_status 标为 temporary_default,最终质量等级最高为 provisional_pass

What ships with it

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.

ez-math-model is a skill published in the GitHub repository woodfishhhh/EZ_math_model (40 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 3,637 once invoked, about $0.0002 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.
