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 | $0.00034 | $0.02441 |
| Opus 5.5 | $0.00014 | $0.00976 |
| Sonnet 5.5 | $0.00007 | $0.00488 |
| Haiku 4.5 | $0.00003 | $0.00244 |
Grade A, and why
reference-manager 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 — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Manage and verify references for mathematical modeling contest papers.
This skill checks that every cited reference corresponds to an actual source, verifies that citations are placed where evidence is needed, generates properly formatted BibTeX entries for all references, and ensures that the paper does not contain fabricated citations.
This skill does not search for new papers, write paper sections, select methods, or perform QA on modeling content.
When to use
Use this skill:
- After
paper-section-writerhas drafted paper sections with citations. - Before
quality-assurance-auditor. - When the user says: "check the references", "generate BibTeX", "verify citations", "build refs.bib", "check if all citations are real".
- When the paper has
\cite{...}or bracketed reference markers that need verification. - When the related-paper analysis produced paper references that need to be formatted.
Preconditions
The following should already exist or be provided:
- Paper section drafts with citations (
\cite{...}or [1], [2], etc.). - Related paper analysis at
workspace/papers/related_paper_analysis.md(if available). - User-provided paper files under
workspace/papers/(if available).
Inputs
Use or request:
paper/sections/*.mdorpaper/sections/*.tex— paper drafts with citations.workspace/papers/related_paper_analysis.md— literature analysis with paper metadata.- Paper files under
workspace/papers/(PDF, etc.) for metadata extraction. - Any existing
.bibfile the user has prepared. - User notes about which references are most important.
Workflow
-
Inventory all citations in the paper.
- Scan all paper sections for
\cite{...}commands,[N]markers, or author-year citations. - Build a complete list of unique citation keys or reference numbers.
- Note where each citation appears and what claim it supports.
- Scan all paper sections for
-
Match citations to source information.
- For each citation, try to find its source:
- In
workspace/papers/related_paper_analysis.md— if a paper was analyzed. - In user-provided paper files under
workspace/papers/. - In user-provided BibTeX or reference lists.
- In
- Mark citations that cannot be matched as "unverified".
- For each citation, try to find its source:
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.

reference-manager is a skill published in the GitHub repository zhnnky329/MathModeling-skills (1,080 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 2,441 once invoked, about $0.0001 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.
