What problem does it solve? When writing the 问题分析 (problem analysis) section of a Chinese mathematical modeling competition paper, it is easy to misclassify tasks, fabricate data claims, break cross-question linkage, or leak results that belong in later chapters. This Skill diagnoses those issues against the original problem statement before submission. ## Core Features & Use Cases - Task Coverage Mapping: Maps each original problem task to its paragraph in the draft, checking mathematical-type classification and planned outputs. - Cross-Question Linkage Audit: Verifies real data, parameter, constraint, and result flows between questions, flagging missing or fabricated links. - Chapter Boundary Check: Detects premature results, formulas, error values, or program details that violate the problem-analysis section's scope. - Use Case: A modeling team pastes the full competition problem and their drafted 问题分析; the Skill returns a severity-graded issue list, an evidence-vs-assumption breakdown, and the top three revision priorities. ## Quick Start Use the bzd-problem-analysis-checker to review my drafted 问题分析 against the attached original competition problem and list issues with revision priorities.
