MathModeling-skills: Hook for Claude Code

.claude/settings.json

SessionStart is a hook for Claude Code from zhnnky329/MathModeling-skills. Its token cost is not measured, scanned A, original, MIT.

A startup hook that runs a shell command when a coding session begins. The command prints reminders about protected files, git push controls, and an audit check for assembled work.

In plain words
What is it for?
Use it to announce guardrails when working on the referenced math-modeling project, including immutable data files, gated pushes, and the required audit status.
Why use it?
It places project-specific safety reminders in front of the agent at the start of every session. The provided setup only displays a message; it does not show that it enforces these rules.

Hook for Claude Code

Written for Claude Code: SessionStart hook event. Also seen: mentions CLAUDE.md.

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 →

One of 2 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

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.

Security

Grade A, and why

SessionStart 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 commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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 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.
