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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00620 |
| Opus 5.5 | $0.00016 | $0.00248 |
| Sonnet 5.5 | $0.00008 | $0.00124 |
| Haiku 4.5 | $0.00004 | $0.00062 |
Grade A, and why
matlab-model-code-generator 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.
How it starts
The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Preconditions
- G2.5 human method choice is recorded.
code/matlab/Qx/qx_code_plan.mdexists.- Required cleaned data and profile exist.
- The plan targets MATLAB or 北太天元.
Legacy artifacts may be read during migration but do not override the human decision.
Workflow
- Read the code plan, decision ledger, method card, probe conditions, and data profile.
- Confirm scope: approved main plus usable baseline. Implement a fallback only after activation.
- Generate conservative
.mfiles undercode/matlab/Qx/. - Prefer basic matrix/table operations and avoid optional toolboxes unless the plan approves them.
- Save tables, metrics, useful figures, and
run_summary.jsonunderresults/Qx/experiments/roundN/. - Evaluate output-degeneracy and fallback-trigger metrics required by the plan.
- Use
diaryor another full log only for a failure or reproducibility warning. - Run in the available compatible runtime. If unavailable, report the unexecuted state explicitly.
- Hand off to
code-reviewer.
Script Layout
code/matlab/Qx/
├── qx_code_plan.md
├── qx_baseline.m
├── qx_main.m
└── run_all.m % only when useful
Do not create scripts for unapproved candidates or a duplicate README.
Compatibility Rules
- Prefer
readtable,readmatrix,writetable,writematrix,save,load, andfullfile. - Use
rng(2026)or the recorded seed. - Use
jsonencodewhen supported; otherwise write the required JSON fields deterministically. - Avoid Live Scripts, App Designer, GUI code, Simulink, and toolbox-only functions unless explicitly approved.
- Note any 北太天元 compatibility risk in the run summary.
Run Summary
Follow the model-code-analyzer contract, including approved decision ID, roles, paths, metrics, output-degeneracy evidence, fallback state, timing, seed, environment, warnings, and errors.
Rules
- Do not change the selected mathematical method.
- Do not access or overwrite raw data.
- Do not fabricate successful execution when MATLAB/北太天元 is unavailable.
- Keep only evidence-bearing intermediate outputs.
- Separate Type 1 diagnostics from paper figures.
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.

matlab-model-code-generator is a skill published in the GitHub repository zhnnky329/MathModeling-skills (1,080 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 620 once invoked, about $0.0002 per session on Opus 5.5. 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.
