MathModeling-skills: Skill for Claude Code

.claude/skills/code-reviewer/SKILL.md

code-reviewer is a skill for Claude Code from zhnnky329/MathModeling-skills. It costs 33 tokens per session (228 once invoked), scanned A, original, MIT.

A code-review router that identifies whether approved modeling code is written in Python or MATLAB/Beita Tianyuan and sends it to the matching reviewer.

In plain words
What is it for?
Use it to route Python and MATLAB files and check syntax, input handling, alignment with the chosen method, reproducibility, and expected outputs.
Why use it?
It avoids reviewing code with the wrong language-specific process and makes the required review checks explicit.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is zhnnky329/MathModeling-skills's own configuration. It tells Claude Code how to work on MathModeling-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything MathModeling-skills configures →

About the project

MathModeling-skills is a collection of Claude Code and Codex skills for mathematical modeling competitions, guiding users through data analysis, method-specific checks, reproducible computations, figures, and paper audits without taking over modeling decisions. It is for contestants who want AI to handle mechanical checks while they retain responsibility for choosing methods and interpreting results. The catalogue entries form the project's skills, instructions, hook, setting, and plugin workflow.

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

code-reviewer 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 2mo 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.

What it actually says

Workflow

  1. Inspect target code extensions and the implementation target in qx_code_plan.md.
  2. Route .py work to python-code-reviewer.
  3. Route .m work to matlab-code-reviewer.
  4. If both languages are intentionally present, review each separately.
  5. If the language or target is ambiguous, report the exact conflict.

Review Contract

New reviews write JSON and evaluate these named checks:

  • syntax
  • input_contract
  • method_alignment
  • reproducibility
  • output_contract

Additional checks are allowed when risk-driven. A review passes when all required applicable checks pass; no arbitrary bullet count is used.

Rules

  • Do not perform a second independent review in this router.
  • Do not infer success because scripts exist.
  • Do not require a Markdown review when the canonical JSON review exists.
  • Read legacy Markdown reviews only for compatibility.
Changes

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.
