Generate stable and competition-style LaTeX mathematical modeling paper projects for MCM/ICM and CUMCM. Use when Codex needs to create, adapt, compile, or preflight competition paper templates for COMAP MCM/ICM, Chinese Undergraduate Mathematical Contest in Modeling (CUMCM), or similar mathematical modeling submissions, including mcmthesis, cumcmthesis, XeLaTeX, latexmk, PDF page/size checks, identity-info checks, references, appendices, and AI-use disclosure sections.

Create, validate, repair, import, and package high-resolution Tauri desktop pet packages for the Desktop Pet Launcher. Use when the user asks for a desktop pet, Tauri pet launcher assets, hatch-pet-compatible pet packages, tray pet packaging, high-DPI spritesheets, or pet.json/spritesheet.webp validation. Prefer 4x master spritesheets and export 1x compatibility assets instead of upscaling small hatch-pet output.

Use this skill whenever the user asks for Codex token usage, Codex cost, token consumption since a date, remaining Codex quota/limits, cache-hit tokens, model-by-model pricing, or a receipt/report/PDF/printout for Codex usage. This skill should also trigger for Chinese prompts asking to print a Codex token spending receipt, show token consumption and quota remainder, count both Windows and WSL, list model prices, or make the result look like a receipt/report. It is especially important when raw Windows and WSL Codex JSONL logs must be reconciled and when the output should be a polished black-and-white receipt rather than a prose explanation.
