What problem does it solve? Manually converting medical device standards (GB 9706, YY 9706 series) into registration-submission test cases is slow and error-prone: clauses get skipped, limits get invented from memory, and coverage gaps surface only during audits. This Skill decomposes every clause of a standard into minimal executable test units with verbatim-sourced limits and generates a fixed-format Excel test case library. ## Core Features & Use Cases - Clause-by-clause decomposition: Splits standard text into minimal executable test units using four case forms (chapter-level fallback, clause body, document review, normative-reference expansion) to prevent systematic omissions. - Traceable limits and criteria: Test environments and acceptance criteria are quoted verbatim from clause text or normative references, with source annotations and manual-review flags instead of invented parameters. - Fixed 12-column Excel output: Generates a frozen-header workbook with dropdown validation, dual product/module code classification (8 + 11 codes), clause-index existence and continuity checks, and blocking validation against real coverage gaps. - Use Case: Upload YY 9706.262-2021 or GB 9706.224-2021 and receive a complete, clause-ordered Excel test case library ready for registration submission or QA review. ## Quick Start Upload the standard PDF and ask the assistant to decompose all clauses of this standard into test cases and generate the Excel file with medium granularity and reference expansion enabled.
