Description

This skill helps product managers and business analysts reverse engineer detailed product requirements document (PRD) logic from front-end page descriptions or interaction descriptions. It converts visual front-end information into structured backend business logic, focusing on data flow, business rules, and state changes. As a senior product logic architect, this skill deeply explores the business essence behind the page. It helps you sort out the page's commercial positioning in the product chain, user entry prerequisites, and derives backend data field structures based on front-end elements. It also clearly defines how user interactions trigger business state transitions and elaborates on core business rules such as data validation, calculation distribution, concurrent processing, and anti-fraud. To ensure rigorous product logic, this skill exhaustively considers the invisible "underwater logic" on front-end pages, including exception handling, network delay handling, and permission checks. The final output PRD logic section covers exception boundaries and degradation strategies, such as empty state handling, boundary limits, and responses to extreme exceptions. You only need to provide a front-end page description, interaction flow, or screenshot, and this skill generates a clear, logically rigorous PRD core content, greatly improving product documentation efficiency.
