Turn raw study material (PDF problem sets, lecture slides/PPTX, or pasted text) into cleanly formatted Chinese LaTeX revision papers. Routes to two cooperating sub-skills: exerpaper (problem set -> step-by-step solution manual with knowledge-point summaries) and testpraper (slides/notes -> exam sprint manual with concept/step/example boxes). Trigger when a user wants 自制复习资料 — a polished solution PDF or 冲刺讲义 — from their own course files.
