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 | $0.00038 | $0.00493 |
| Opus 5.5 | $0.00015 | $0.00197 |
| Sonnet 5.5 | $0.00008 | $0.00099 |
| Haiku 4.5 | $0.00004 | $0.00049 |
Grade A, and why
math-figure-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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Preconditions
- Figure type, source artifacts, and target claim are known.
- Type 3 claim is human-confirmed.
- Submission figures use final/frozen evidence.
References
Load only what the requested chart needs:
references/chart-patterns.mdreferences/color-systems.mdreferences/layout-guide.mdreferences/render-check.md
Workflow
- Verify source files and the exact variables/units to plot.
- Choose the smallest chart form that communicates the claim.
- Generate with deterministic code, preferably matplotlib.
- Save editable source code and the requested output format.
- Apply the shared color, typography, sizing, and labeling conventions.
- Render the final output and inspect it visually.
- Check clipping, overlap, illegible text, misleading axes, legends, empty panels, and source/claim mismatch.
- Iterate until render checks pass.
Output Locations
- Type 1/2 exploration:
results/Qx/experiments/roundN/figures/ - Type 3/4 submission:
paper/figures/
Use stable descriptive filenames. Do not copy Type 1 diagnostics into the paper directory.
Figure Requirements
- Labels include units where applicable.
- Captions state what is shown and the evidence-backed takeaway without overstating causality.
- Baseline is visually distinct but not exaggerated.
- Uncertainty is shown when it is part of the claim.
- Type 3 raster output is at least 300 dpi; vector output is preferred when compatible.
- Accessibility and grayscale differentiation are considered.
Rules
- Do not fabricate or manually alter plotted values.
- Do not use a chart type that hides concentration, uncertainty, or negative results.
- Do not truncate axes misleadingly.
- Do not create decorative 3D effects.
- Do not treat code execution as render verification.
- Keep diagnostic and paper roles separate.
Verification
- Source, claim, type, and target section agree.
- Render inspection passed.
- Text is readable at final paper size.
- Legends, colors, markers, axes, units, and captions are consistent.
- Final output path exists and is recorded in the figure plan.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

math-figure-generator is a skill published in the GitHub repository zhnnky329/MathModeling-skills (1,080 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 493 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.
