Is the EZ Math Model skill free?

Yes. The skill itself is free from woodfishhhh/EZ_math_model. SkillProof publishes the install command and an independent test verdict at no cost.

What is the EZ Math Model SkillProof Score?

8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 6/10, docs & honesty 4/5.

How do I install EZ Math Model?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use EZ Math Model with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Q: Does EZ Math Model work with Claude Code?

We tested it with Claude Code 2.x (agent harness) on Jul 14, 2026. Verdict: Tested · Works. Its own algorithm-selection table flags this dataset (n=10, <15) for GM(1,1) grey prediction over linear regression, but a real held-out test showed plain linear regression beat GM(1,1) (0.42% vs 1.78% MAPE) — the skill's process/packaging scaffolding is the real value-add, not the auto-picked model.

What EZ Math Model does

Orchestrates a full math-modeling-contest workflow — problem intake, model selection from a built-in algorithm library, Python solving, chart quality gates, paper writing, quality audit, and zip packaging. Triggers on CUMCM/MCM/ICM/国赛/美赛 mentions or uploaded contest problem statements with multi-part questions and datasets.

How to install EZ Math Model

git clone https://github.com/woodfishhhh/EZ_math_model
cd EZ_math_model
mkdir -p ~/.claude/skills
cp -r skills/ez-math-model ~/.claude/skills/ez-math-model

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
