Choose the LaTeX engine when prompted, and the Skill copies the matching contest template (e.g., zh/cumcm-latex) into a paper/ directory. You then fill section files with content grounded in the results report and compile twice with xelatex to resolve cross-references.

Chinese templates cover apmcm, changsanjiao, cumcm, default, diangongbei, dongsansheng, huashubei, huaweibei, huazhongbei, mathorcup, mcm, shuweibei, stats, and wuyibei. English templates cover apmcm, default, and mcm, each in both Typst and LaTeX versions.

LaTeX with xelatex is the default and recommended choice since all templates are ready and it is the mainstream format for these contests. Typst is available as an alternative and uses the typst-author skill for syntax assistance.

No. Final paper figures must come only from figures/final/, and all numbers must come from RESULTS_REPORT.md and the current run's authoritative results. Fabricating, estimating, or altering rounding is explicitly forbidden.

Cross-references and tables of contents require two compilation passes. Run xelatex -interaction=nonstopmode main.tex twice so labels, citations, and the contents page resolve correctly.

The appendix is generated from delivery_manifest.json and includes only complete source programs that demonstrate the main models, core algorithms, and key validation methods. Trivial parameter-forwarding mains, simple field checks, and pure plotting scripts are excluded.
